I was trying to figure out a way to protect the bottom of a glass tank from a catastrophic failure in the instance that a fish, whether it be FW
, would dig out the substrate underneath a rock structure, causing it to settle into the bottom glass hard enough to crack it - which, or course, would be very much bad. I got the idea that putting down egg crate would do the job. Has anyone tried this?
This initially would be for a FW
225 Glass that I would be setting up as a cichlid tank with pool filter sand as a substrate, possibly with some crushed coral mixed in (but that might just be put in the sump). What I was going to do was put down the egg crate, fill in the sand to cover it up, build the rock structure for the cichlids on that, and them fill in about another inch or so of sand, so the rocks would initially be sitting on the egg crate.
I thought this might work well because from what I've heard about PFS, it doesn't allow waste to settle into it, so I wouldn't be causing an anaerobic pocket. Even if I was, the egg crate is only 1/4" thick, and 5/8" holes, so it wouldn't be like you couldn't suck the substrate out if need be (not worried about that anyways).
I also thought this might work well in a SW
tank with heavy LR
. In either case, I suppose it might work just as well to put the rock in first directly on the glass, but has anyone else tried this with success, failure, or somewhere in between?
