I have a 120 gal tank that has been established for 8 months. It contains about 20 fish (mostly cichlids, a few cats, an oscar and a pleco). Very healthy fish that grow well. I've only lost about 4 or 5 fish over the 8 months, mostly from aggresive fish. I started out with plants but the little buggers dug all but 2 up (all will be replaced with fake ones). I have an undergravel filter and lots of gravel substrate. I am switching out the ug filter due to seemingly unchangable nitrate levels and the digging cichlids keep exposing it. I actually posted another post regarding changing out the ug filter (thanks for the responses).
Now I am thinking about switching the gravel out for sand but I think this may be too much of a switch. I'm looking for your thoughts on this topic. Should I just leave the gravel? Should I switch for sand to help keep up the PH level? If I do switch out the sand, what is the best method?
Looking for your responses. This is a great forum, filled with very helpful folks.
