seabass Posted October 12, 2020 Author Share Posted October 12, 2020 I did testing today (10/12/20): 40 Gallon 10/12/20 10/03/20 Alkalinity: 15.7 dKH >16 dKH Phosphorus: 6 ppb* 0 ppb Nitrate: 0.0 ppm 0.0 ppm 100 Gallon 10/12/20 10/03/20 Alkalinity: 12.5 dKH 13.1 dKH Phosphorus: 17 ppb** 3 ppb Nitrate: 0.2 ppm 0.0 ppm * Phosphorus of 6 ppb = 0.018 ppm of phosphate. ** Phosphorus of 17 ppb = 0.052 ppm of phosphate. I didn't get my water change done yesterday, so I didn't dose Vibrant today. Hopefully I'll get both done tomorrow. Also, I have some calcium nitrate from AquariumFertilizer.com that I think I'll start dosing. I'd be happier with nitrate closer to 2 to 5 ppm. 3 Quote Link to comment
seabass Posted October 13, 2020 Author Share Posted October 13, 2020 So I did complete my water changes and Vibrant dosing today. Dose 2 - Week 2 I still have much work to do on both sand beds, but I'm limiting my water changes to just prior to dosing. I suppose that means I can perform additional water changes once I start dosing twice a week (in week four). 3 Quote Link to comment
seabass Posted October 15, 2020 Author Share Posted October 15, 2020 Some pics from today: 100 Gallon: You can see that the rock, where I scraped off the bubble algae, is still clean and white. A couple of heavily covered rocks. 40 Gallon: 4 Quote Link to comment

seabass Posted October 17, 2020 Author Share Posted October 17, 2020 More testing today, 10/17/20: 40 Gallon 10/17/20 10/12/20 10/03/20 Alkalinity: 14.1 dKH 15.7 dKH >16 dKH Phosphorus: 4 ppb* 6 ppb 0 ppb Nitrate: 0.0 ppm 0.0 ppm 0.0 ppm 100 Gallon 10/17/20 10/12/20 10/03/20 Alkalinity: 12.3 dKH 12.5 dKH 13.1 dKH Phosphorus: 23 ppb** 17 ppb 3 ppb Nitrate: 1.0 ppm 0.2 ppm 0.0 ppm * 0.012 ppm phosphate ** 0.067 ppm phosphate I haven't dosed any nutrients yet. I'm guessing that the nutrient increase in the 100 gallon could be due to disruptions in the sand bed. I should be able to get in another water change this weekend, so that I can dose Vibrant on Monday. Also note that I've been trying to slowly bring down alkalinity, so I don't believe that Vibrant has caused these declines. 2 Quote Link to comment
seabass Posted October 19, 2020 Author Share Posted October 19, 2020 I did water changes and dosed Vibrant today (week 3). Here's the resulting carnage (from the water change) in my 100 gallon tank. The sand bed is still very dirty. I'm kind of looking forward to next week, when I'll be performing two water changes, as I switch to dosing Vibrant twice a week (with water changes prior to each dosing). Once I finally get the tank cleaned up, I'll revert back to doing weekly water changes, even though I'll continue dosing Vibrant twice weekly. One might suspect that changes could be due to the increased maintenance. And while I'm pretty sure that it will impact the tank and corals, I'm equally sure that maintenance wouldn't fully rid either of these tanks of algae. Again, I would probably recommend deep cleaning your tank prior to dosing Vibrant. However, obviously, I didn't do this myself. I guess I got a little ahead of myself. 3 Quote Link to comment

Just want to mention that I'm pretty good about regular maintenance, usually doing water changes at least bi weekly and often weekly, and I'm still battling a pretty bad algae outbreak. I think I tend to overfeed though. Going to order some vibrant and give it a try. You think it will kill Macros? 1 Quote Link to comment

To save them, I put the macros in another tank until treatment was completed. But ended up converting that holding tank into another cardinalfish nursery. 1 Quote Link to comment

seabass Posted October 23, 2020 Author Share Posted October 23, 2020 A couple more notes going forward: I'll start to dose Vibrant twice a week. And until I get the sand bed clean, I'll do water changes prior to each dose (then back to weekly water changes). I recently switched to RO (with 3 TDS product water) over RO/DI to save money; but I don't foresee any other benefit from the removal of the DI stage. I also plan to use up my remaining bottle of DrTim's Waste-Away (a bacterial supplement), and use the Waste-Away gels, which I purchased previously. 2 Quote Link to comment

seabass Posted October 24, 2020 Author Share Posted October 24, 2020 I did a water change on both tanks yesterday. But I plan on doing another one this weekend (maybe today) because my 100 gallon tank is experiencing additional cyano. I'm going through so much more salt these days. As I stated before, I feel that cyano is primarily due to organics (in the sand bed, on the rocks, and dissolved in the water column). Dosing Vibrant breaks down algae and produces lots of organics which are trying to be broken down by bacteria. Cyano grows on top of the sand bed because it's photosynthetic and cannot grow in the dark. The more I get into this, the more I see this process, of breakdown and increased organics, playing out. Maintenance while dosing seems critical. And if I could have a do-over, I would have done a deep clean prior to dosing Vibrant. I feel that I'm playing catch up for past neglected maintenance, while also dealing with the additional organics being generated by the breakdown of algae. As far as algae is concerned, I really feel that Vibrant has taken it's toll on the algae. And while algae is still very much still present, there are notable changes in both tanks. If the tanks looked like they do now, I probably wouldn't feel the need to dose Vibrant. However, both of these tanks still have a Looonngg way to go in order to be algae free. I'll continue to post pics (hopefully weekly). The turf algae is starting to look more like moss (much shorter). I also believe that as the bacteria continue to work on the algae, the more effective the existing cleanup crew becomes. 2 Quote Link to comment
seabass Posted October 24, 2020 Author Share Posted October 24, 2020 While it might be more convenient to dose Brightwell NeoNitro and NeoPhos, I'm dosing dry nutrients. Here's a calculator to anybody dosing dry ferts: https://rotalabutterfly.com/nutrient-calculator.php My plan is to start to try to bump nitrate to between 2 and 5 ppm. I'm alright with the current levels of phosphate in both tanks. 1 Quote Link to comment
seabass Posted October 25, 2020 Author Share Posted October 25, 2020 I had a weird thing happen in my 100 gallon tank today. After I finished my water change, I dosed a small amount of Waste-Away. A few minutes later and my skimmer cup was full of water. I ended up skimming out more than 5 gallons of water before it stopped. I did the exact same thing in the 40 gallon tank, but with no reaction from its skimmer. I'm not sure, but I believe the skimmer's reaction might have been triggered from disturbing the sand bed (along with the Waste-Away). I doubt that anything is wrong, but just thought I'd note this unusual reaction. 1 Quote Link to comment
seabass Posted October 25, 2020 Author Share Posted October 25, 2020 Also, I'm debating whether I should shorten the light cycle (primarily to help limit cyano, but maybe it will also help the general fight against algae). Currently, the light cycle (for both tanks) is 7 hours of T5s. I'm considering, shortening it down to 6 hours. I'm making slow progress on cleaning up the sand bed. So I'm even thinking about doing one more water change today, before I start dosing Vibrant twice a week (starting on Monday). I think as long as there is algae in the tank, I will continue to do a water change each time prior to dosing more Vibrant. I think it's important to keep up on all the organics being released. 1 Quote Link to comment
seabass Posted October 26, 2020 Author Share Posted October 26, 2020 I ended up shortening the light cycle to six (versus seven) hours. I also need to change my T5 bulbs over both tanks (chances are that the spectrums have shifted, in the favor of algae). I'll provide an update if/when I get new bulbs (I'm looking for a sale if possible). Also, I performed three water changes over the last three days (in each tank). I still have work to do on the sand beds of both tanks. Tomorrow will be the fourth week, and the first week of dosing twice a week. I think you will start noticing some effects in the pics this week. 2 Quote Link to comment
DSFIRSTSLTWATER Posted October 26, 2020 Share Posted October 26, 2020 I'm loving the updates. You've gotten way more technical than I ever did and it's awesome. The sand bed issues I'm so glad I don't have to deal with lol. I will say bare bottom was way harder to get started initially though. Keep up the great progress 😊 1 1 Quote Link to comment

I don't want to siphon it all out as I feel there is beneficial micro-fauna in it. But I should have plenty of sand to add more, so I've been tossing it. My 40 gallon tank's sand bed is peppered with baby rock flower anemones, so I have to be more careful in there. However, I feel that this bed isn't nearly as bad as the other tank's substrate. 2 Quote Link to comment

seabass Posted October 27, 2020 Author Share Posted October 27, 2020 I think it's time to start nitrate dosing. Awhile ago, I purchased a pound of dry calcium nitrate (CaNO3) from Planted Aquarium Fertilizer. I think I worked out a dosing procedure (if anybody wishes to check my math). Using the Rotala Butterfly nutrient dosing calculator above, I came up with the following: Given the calculator's result, I should need 0.005 tsp (1/200th of a tsp) of dry nitrate to raise nitrate by 0.9 ppm in 10 gallons of water. If I add 1 tsp of calcium nitrate to 6 oz (177 ml) of water, and I want to dose 1/200 of that, then I would need to dose 0.9 ml of that solution. So dosing 1 ml of the solution into 10 gallons of tank water, should raise nitrate by approximately 1 ppm. My plan is to raise nitrate by no more than 1 ppm each day. So I'll do a sanity check by test dosing 4 ml of the solution into the 40 gallon tank first (and then re-test it). 1 Quote Link to comment

Foster & Smith clearance (going out of business) sale. These bulbs wouldn't be my first choice, but they should be fine. Now I'm just trying to figure out when I put the old bulbs in. 🤔 1 Quote Link to comment
seabass Posted October 28, 2020 Author Share Posted October 28, 2020 Holy crap, according to my records, the bulbs I'm using are well over 2 years old. Looks like I'm changing bulbs tomorrow. 2 Quote Link to comment
seabass Posted October 30, 2020 Author Share Posted October 30, 2020 The new T5 bulbs fluoresce a little better than the old ones were doing, and the purples are less brown looking. Hopefully they will not be as algae friendly, and assist the work that Vibrant has been clearly doing. Today I performed another water change, added the fifth dose of Vibrant (the second dose this week), and dosed more nitrate. I almost held off on increasing the dosing frequency, as the cyano in my 100 gallon tank is still very much present. I also ordered a detangle comb, which I plan to use as a sand bed rake. I'm not quite sure how that's going to work out yet, but I feel a rake might prove handy in cleaning up the sand bed. If nothing else, I'll have a couple of Zen gardens to play with. 1 Quote Link to comment
seabass Posted October 30, 2020 Author Share Posted October 30, 2020 I took some photos today. 100 Gallon: My clownfish have still been breeding roughly every 10 days. You can see that the red grape currently still seems basically unaffected. The sand bed is getting sparse in areas. 40 Gallon: 1 Quote Link to comment
