i have had fish tanks for years. i have several fresh water and one salt water. over the past few weeks i am embarking on a new tank, something i have always wanted to do, Discus' i have been doing a lot of research on them over the internet and i think things are going good. i have a 60gal hex tank. i am using an RO
filtering system and i have my water test kits. In my fourth week of the tank being up and running (no fish) my water levels are perfect.
i have a very large piece of drift wood that sitting on the bottom still sticks out the top of water about an inch or so. looks pretty cool.
The only thing i am worried about at this point is the water hardness. I have read about adding peat moss to the filter, but i dont know is it safe to just go to the local garden center and get "peat moss" or buy it online in pellet form?
can anyone please give me advice as to what to do next. Thanks.
