aclman88 posted a topic in Water ChemistryHey guys and gals, I have a 5 gallon pico (link is in my signature) and have noticed that the Alk has been running a little on the low end. Coral consist of softies, LPS and a couple SPS frags. I recently switched to Tropic Marin Pro Reef. My Alk is testing in around 6.5-7.0 after water changes, which is a little lower than TMPR mixes up to. (~7.7) I was using Instant Ocean Reef Crystals with great success, but this is supposed to mix up at a much higher Alk and the batch I recently mixed and tested is only hitting high 7s in Alk. I don't like the inconsistency I am seeing in this batch. I also realize that if I continued using Reef Crystals for my usual one gallon water change, and it is mixing up at advertised 13 alk, my tank would jump from 6.4 to over 8 in a single water change, which I think is too much. Two weeks ago, I tested the Alk daily using a Hanna checker and found about .1 Alk drop every two days. Below is the testing results I performed this past week after a water change; it looks like the tank is using up about .1 Dkh Alk daily. All tests were done with the salifert, and I used a hanna checker a bunch of the days as well. Freshly Mixed Tropic Marin Pro Reef Levels: Alk - 7.7 Cal - 425 Mag 1305 3/29 - After 25% Water Change (~1 Gallon) Alk - 6.8 Cal - 395 Mag 1245 3/30 - Alk - 6.7 Cal - 395 Mag 1260 3/31 - Alk - 6.5/6.6 Hanna Alk - 6.7 Cal - 395 Mag 1260 4/01 - Alk - 6.5 Hanna Alk - 6.4 Cal - 395 Mag 1275 4/02 - Alk - 6.4 Hanna Alk - 6.3 Cal - 385 Mag 1245 4/03 - Alk - 6.4. Hanna Alk - 6.2 Cal - 395 Mag 1245 4/04 - After 25% Water Change (~1 Gallon) Alk - 6.55. Hanna Alk - 6.7 Cal - 395 Mag 1305 I don't think that water changes will keep up with this drop since after a water change I am still below 7 Dkh. My question is, should I be dosing this tank or just perform larger water changes to keep up with the demand? I already have the ESV B-Ionic two part system, so if I am dosing I will be using that. If so, should I be performing a couple larger water changes first to get parameters closer to what my salt mixes up to? Any advice or experience dosing such a small tank would be really great. Thanks!
Hi guys I've had continuous slight algae issues (cyano on the sand and hair on live rock; I also have a sulking Duncan which made me try to improve params) since taking over this tank, and have decided to do something about it. I'm using NO3PO4X consistently at the suggested dose and have seen my nitrates fall to around 10ppm from 20+ppm. However, I don't have any detectable phosphate or nitrite. At this level, should I still be getting algae growth? I would think that 10ppm nitrate and 0 nitrite/phosphate should be good enough. I'll keep aiming to bring the nitrate down with NO3PO4X until it stabilises, as per the instructions. Anyone have any ideas if I'm barking up the wrong tree or should be doing something different? Tank size (volume) - 16 gallons Tank age - 2 years (moved and rescaped 6 months ago) Lighting - AI Prime Nitrate - 10 (fallen from 20 2 weeks ago) Nitrite - 0 Phosphate - 0
Hello I've just done a set of test crica. 30 mins after a 10% water change, and plan to do one every day until my next change (1 week) to see if there's anything I can spot that could be causing my algae issues, as well as try to find out why my Duncan is sulking (has been for about 2 weeks). Ammonia - 0 Nitrate - 20 Nitrite 0 pH - 7.6 Alkalinity - 9 As you can see, my nitrate levels are slightly high, which could be causing my algae issues. I will try to stick to feeding every other day, and skimming slightly wetter to see if that helps. The main issue however is my pH and alkalinity. These are clearly slightly lower than would be considered ideal. How might I go about bringing them up a touch? I'll continue to test for a week and see if instability could be the cause of my Duncan issues. Any advice I'd be grateful of!
