Wonderboy Posted May 17, 2019 Author Share Posted May 17, 2019 So this morning, I figured I'd try doing something mildly ridiculous and search the internet to see if anyone else had some obscure reason to put pea gravel in a reef tank and had any experience thereof: https://www.reef2reef.com/threads/imagitarium-substrate-kills-pests-along-with-almost-everything-else.598716/ Figured as much. Today, I will be moving all livestock to quarantine and breaking this tank down. I don't know if I even trust the rock anymore... I will be setting it back up as soon as I can. I have been thinking of adding a sump to remove some equipment from the display and also incorporate temperature control in the meantime. 1 2 2 Quote Link to comment
Wonderboy Posted May 17, 2019 Author Share Posted May 17, 2019 Vinegar test suggested that the gravel was inert, and still I rinsed it well, but I always had an unsure feeling about it from the get go. Check this out - shot looking at the bottom of the tank: Beautiful, huh? So this is where all my brown algae has been growing but I expected this - I figured the brown stuff would dominate here until the chaeto filled in; that's why I thought the stomatellas where important. I had been doing my best to keep dwarf cerith out of here because I didn't want any tiny black shells multiplying and ending up on the glass bottom. As for the chaeto, it was starting to grow quite well: 3 1 Quote Link to comment

debbeach13 Posted May 17, 2019 Share Posted May 17, 2019 Are you saying that if you didn't use the pea gravel that the under gravel fuge would have worked? Are you going to try again with a different substrate? Quote Link to comment

Are you going to try again with a different substrate? Yes, I think it would have worked; to me, it seems as though the amount of chaeto that I had just about doubled in size. I had to break up the dark green, intergrown clumps a bunch to see if there was any necrosis from too little/much light - didn't see any, it was looking quite healthy. Another picture: I do plan on running the UGFuge again - you're right, with different substrate (maybe small shells) - and possibly with some additional modifications 2 Quote Link to comment
Tigahboy Posted May 17, 2019 Share Posted May 17, 2019 Sorry to hear about the DQ and having to reboot, but I'm sure things are about to get crazy up in here now that you have zero constraints. Looking forward to seeing what you tricks you have in store. 4 Quote Link to comment

Christopher Marks Posted May 17, 2019 Share Posted May 17, 2019 Arg a frustrating setback on the substrate @Wonderboy, that sucks! At least you were able to catch the issue in advance. It is really cool to see the chateo had already doubled in that time. Are you concerned about not being able to harvest the algae once it fills in the area? 2 Quote Link to comment
seabass Posted May 17, 2019 Share Posted May 17, 2019 I'd like you see you figure out the UGF. However, sounds like you now have a chance to use approved equipment and get back into this contest (if you really wanted to). 3 Quote Link to comment

Not really - I don't 100% agree with the idea that chaeto stops uptaking nutrients when it reaches certain mass. I've always trusted secondary metabolism to adhere to consistent environmental stimuli and just let chaeto find its threshold mass and then metabolically balance from there. Algaes are known for exhausting more compounds, that are derived of both macro (especially nitrogen) and micro nutrients, into the water column aside from oxygen. These include secretion from enzyme production that contains amino acids, fatty acids, antioxidents, etc. Algaes are constantly producing/exhausting these things whenever photosynthesizing to protect itself from foreign invasion and assure self persistence. Soooo, I've always considered it more beneficial to cater to the secondary metabolism of chaeto because if it's not constantly directing nutrients to structure, then I know it is prioritizing available photosynthetic energy into producing all those other beneficial compounds that all the livestock in its system can benefit from. Orrrrr, maybe I'm just a special type of lazy, but I have never harvested chaeto, I just try to give it as much room as possible and then leave it to its business. I rarely rotate it if it's accessible, but that's about it. I haven't had problems with excess nutrients after the chaetos maxed out, *knock on wood*, but I don't really chase numbers either - if I notice more pods or algae than usual, I just tone down the feeding. edit: I have been concerned about detritus and coralline though - I have been thinking about how to handle these... more recent edit: I was going to put a thin magnetic scraper to deal with build-up, but I decided against it - with the stability of the bacteria on the calcite and the rock, it is not unreasonable to take everything, like, EVERYTHING out, clean the glass and put it all back. yet another edit: I found it necessary to thin chaeto growing in a HOB to prevent overflowing. If chaeto near an overflow is allowed to get too thick, then whatever the pump is supplying the area will take on more water than can overflow. 1 Quote Link to comment

748S911 Posted May 18, 2019 Share Posted May 18, 2019 Pico-gate...hahahahahaha!! Sorry to hear about the issue, but now you can add the sump. Like a mini complete 2.5 version 😎 1 Quote Link to comment
Wonderboy Posted May 19, 2019 Author Share Posted May 19, 2019 Progress shots: Since I expanded the old ATO hole so that this new palm HOB filter would fit, and the old feed hole is going to be repurposed as the ATO hole, I have to cut another hole for the new quick feed access - it's going in the HOB lid. I am happy that I'll get more flow through the UGF plenum. I added a shelf to the back of the stand for more tricky business. It's a chunk of terrarium screen lid: The tank and UGF are getting a 10% vinegar bath also. The box thing is one of these - been curious to see how well these would work for small volume systems; they usually have bad reviews, but I've had it for a while (this model is the smallest model: 20L max) so might as well see. Since I'm assuming that this setup is still un-appoved, I intend to drill a hole in the back of the tank - I'm going to add some type of rubble/mud chamber or a small clear area (sump) for some of the natural light behind the system to hit. I am planning to plumb the chiller/heater device to it for water movement. The "sump" should fit next to the chiller/heater. 3 Quote Link to comment
A.m.P Posted May 19, 2019 Share Posted May 19, 2019 When it comes to HVAC at least, you run into diminishing returns really quick when up-sizing, after all the pieces really only run full-tilt or are off and the volume you're working with isn't changing, even if it cools 10% faster. Now undersizing means you put a ton of strain on things and are running constantly because it cant actually achieve a temperature-delta, it's just that oversizing has an unintuitive drawback of using more power for similar results most of the time. Still love this concept, maybe wait a bit before getting the drill out to see if they'll let you get away with the filter in this form. 1 Quote Link to comment
Wonderboy Posted May 22, 2019 Author Share Posted May 22, 2019 I settled on using orange calcite for the substrate. I placed an order today for a bunch from this fantastic old school online supplier: http://www.fish-scapes.com/index.html - I was looking for something that would't fall apart easily and allow flow for long term - it should also help to buffer the pH. I also wanted to try something with color. Curious to see what it will look like in here... 1 Quote Link to comment

I'm not worried at all; I think that the owner of this business is so old school himself that he didn't keep marine aquariums in mind lol https://www.advancedaquarist.com/2011/10/chemistry - related article I think that the orange coloration is the only risk - at the same time it's most likely iron and/or manganese, both of which I think the chaeto would pull sufficiently from the column if ever leeched, but from the article: "calcium carbonate will not dissolve in the water column of normal marine aquaria". 1 Quote Link to comment
seabass Posted May 22, 2019 Share Posted May 22, 2019 The pH caution was likely for freshwater tanks. However, calcite is a poor buffer compared to aragonite. 1 hour ago, Wonderboy said: I think that the orange coloration is the only risk - at the same time it's most likely iron and/or manganese I might try rinsing in a vinegar solution first. Maybe try a few pieces as a test, in case it negatively affects the coloration. 3 Quote Link to comment

The HOB to UGF is a really cool idea too, but it's no surface skimmer 😉 Carry on rule breaking though, this is going to be so cool! I am really curious how that tiny chiller will perform on a system of this size, I'm glad you have one to test out! 6 Quote Link to comment

I went with calcite because it is less likely to break down in the marine environment; I want to avoid long term erosion from physical movement of the substrate (trying to avoid the development of small particulate to keep flow unrestricted and also so light to the chaeto isn't interrupted). I did a few hours of research before making my decision; on the subject of choosing buffers, I had found this to be worth sharing: http://www.seachem.it/Library/Articles/Marine_Water_pH_Control.pdf "It is evident from our experience and the understanding of buffers described above that the addition of calcium ions in the form of carbonates (lime, crushed coral) will ultimately lead to a pK drop, and ultimately, to a buffer at pH 7.6." "Contrary to the prevalent assumptions, we have accumulated extensive data and experience that indicates that marine aquarium pH is better and more easily controlled with inert substrates such as foam, quartz, coated dolomite, oyster shell, than with dissolving substrates, most notably, crushed coral." I was going to go with quartz for the "inertness", but calcite had the argument of originating from the ocean. Still going to try it in some vinegar. Oyster shells were a contestant, too lol - oyster shells are made mostly of calcite. 2 Quote Link to comment
A.m.P Posted May 22, 2019 Share Posted May 22, 2019 Quartz would have been pretty cool, and technically quite a few beaches have quartz-heavy substrate, after all it is a major component of most sands =p The east coast around Orange Beach SC to New York come to mind immediately, the Outer Banks is probably the most well-known quartz-heavy beach... 1 Quote Link to comment

seabass Posted May 22, 2019 Share Posted May 22, 2019 With the prevalence and success of bare bottom tanks, it's pretty clear that it isn't necessary to have your substrate buffer pH. I ran a (salt and pepper) calcite substrate in a contest tank many years ago. Hmm... I often forget about some of my old contest tanks. Maybe it's because I've never won anything. 2 3 1 Quote Link to comment
