I added Kent Discus Essential. pH is 6.0 to 6.5
GH and KH are slightly elevated (perfect) . Nitrite 0. Nitrate 5-8. They seem happy. Also added half dose of seachem nourish for my anubias tied to wood , on my bare bottom. I added half dose of nourish seachem because it has almost the same thing as my Kent Discus Essential. The Nourish seachem has added iron and NPK ...but I don't need alot because anubias are easy to keep .
