Flourite

Just wanted to know what everyone prefers flourite black or flourite black sand?

Non sand type for me, I just like it big enough not to get into the filter intake and I would rather have more space in the substrate, not as compact as the sand. If I did decide I liked sand for looks, I would put some kind of prefilter on the intakes.

You do know the only difference is the actual grain size right?

I haven't seen flourite black sand, but I know flourite black looks the same as regular flourite except it's black. I'm just wondering if people are having problems with the black sand compacting.

Seachem Onyx Sand and Fluorite Black Sand are the same grain size. I have had no issues of compacting with Seachem Onyx sand and so based on this I would say that you should be safe with the Fluorite Black Sand. I got far better growth with Seachem Onyx Sand than I ever did with regular fluorite. For me the growth that I got with regular fluorite was no different than what I saw with Schultz Aquatic Soil. The only difference was the price tag with regular fluorite costing me $38 and the same size bag of Schultz Aquatic Soil costing me $7.00.

Tom Barr has tested many substrates and has set up many tanks and he highly recommends Fluorite Black Sand. I doubt someone like Tom would recommend a substrate prone to compacting.

As far as using any kind of snails to prevent compacting, I would stay away from that unless you have a fish that keep the snail population in check. Snails will multiply like crazy over time and cause huge bioload issues. If you think that not feeding them will keep the population down, think again. I tried that and with the lack of food all they did was turned on and started feeding off my plant leaves. It didn't matter, anubias, java ferns, they were not selective.

In general I would agree with Homer's view on snails, except in the case of MTS. I have a nice population of MTS in all of my tanks that have sandy substrates (I guess even the others these days) and I have never had a problem with them at all. You rarely see then except when the lights are off and I feel they do a good job of keeping the sand fresh. It doesn't seem like MTS are prone to eating plants for whatever reason.

Thanks for your help. I don't plan on having any MTS in my tank, they seem more like pests with the way they multiply so fast.
