I have used vermiculite in my 25g tank - and it's worked perfectly.
About an inch and a half of vermiculite under 2ish inches of flourite,
and any mess comes from all the mulm of a 5yr old tank. None of the
vermiculite has ever escaped. I'm going to be setting up a 75 gallon
tank and I plan on putting a 2 inch layer of vermiculite under a 2 inch
layer of flourite (probably helps that aquarium center in baltimore had
flourite for $11/bag a week ago). I feel that the vermiculite has helped
with the stability of the tank.
I have a question about lighting on a 75. On my 25 i have 4x20w T12
tubes... on my 75 I'm trying to decide what to use. I could stay with
normal flourescent tubes.. but i was contemplating using CF from
ahsupply. Either using 96w tubes or pairs of 55w. I like the fact that 2
55w are 4ft across, covering the entire tank, unlike the 96w tubes which
are like 3 feet long leaving 6" on each side over a 4' tank. So i'm
really thinking about 2 or 4 55w tubes. Anybody have a reccomendations
or comments? Would 220w be too much? too little? Since I also keep a
reef tank, where there is no such thing as too much lighting (ie i have
72w CF ove rmy 10g reef and I wish I had more....) it's strange to tone
it down for freshwater.
