Nice start. If you are in Dallas there are many local fish stores near by you don't have to use Walmart water.
Any reason why you did not start with a bigger tank. The bigger the tank the easyer it is to maintain normally. said:
I have made the Dallas North Aquarium my home LFS....they seem to have a pretty good selection of livestock.
The distilled Walmart water has had no I'll effects, on the label it does state it does go through the RO process but I guess I could just start using RO water from the LFS.
As far as size goes I would like a larger tank but my budget as well as space in my 1bd apt wouldn't allow for it.
