Try searching for this and couldn't find much info.
Is it beneficial to do that or have adverse effect?
As hypo don't cure all disease.
Anyone try before?
buy these rocks as
1) no unwanted pests based on past experience and need special treatment (vinegar soak)
2) not a good sculptor myself and ideal is to have lots of cave for my FOWLR
3) these rocks also come in 3D (means front and back the same) as my tank can be seen thru my kitchen glass partition
yes using compressor for my FOWLR. The fan is on the left side of the cabinet cover with mesh (not wood) and the other 2 side also with either mesh and big lobang behind cabinet. Hope it is enough as there's no obstruction for the fan to blow out hot air now.
