I'd be a bit concerned about cories digging up the sand a bit too much in a dsb. I'm sure it's not a problem to sift the surface and I'm sure it's a totally unjustified fear but I'd want to avoid the risk of one of them digging a hole and letting the nasties out.
Remote deep sand bed for freshwater?

narr see thats the thing, I let them go for gold, ive even seen them up to their eyeballs in sand. So if they do, its giving a greater aerobic zone, pushing the anaerobic deeper. Plus massively assist diffusion to the lower levels & keeps your bed significantly cleaner.
Cories, they are joy to have in my tanks. Sterbai are still my preference.

Picked up two trumpet snails at the LFS today. That's all they had but I got them for free. The snails quickly dug into the DSB after being added in.
As for the worms, I think they're dead or have been eaten up because I don't see them sticking their heads/tails out of the gravel anymore.

Ordered 100+ MTS off the Internet last week and got them today. I put the snails into the DSB and they are doing a great job stirring the top sand around. Every so often, a snail will dig up a patch of sand and release a gas bubble. The MTS definitely work better than the California blackworms.
Just a quick update. I was looking at the deep sand bed this week, and noticed two black spots starting to develop on the right side of the container.
My fish have created one in my 220. It's been there for 6 months. Probably 4-6" deep in one corner. It's in the front of the tank so I can see the black sand and every once in a while I see a nitrogen bubble pop out. I'll try to grab a pic tonight. I'll be breaking the tank down in a few weeks and will remove it then. I've been terrified they would move it but they put it there and seem to like it there. No worms, snails or other critters to help with diffusion. Also no tests on this tank to determine how well it's working. Just an FYI that they do work in freshwater and to some extent without the sand critters.
All bio filters create nitrates. The DSB's, denitrators, plants, resins are a means to remove/lower nitrates between water changes.Miguel;4649500; said:
