Hi -
I've got a community planted tank that has been set up for quite a while, and recently added a few A. agassizii. They're doing great but I'd like to make the conditions more accommodating to them.
The tank has gravel substrate and over the past few months I've been adding a decent amount of leaves, etc. that I got from Tannin Aquatics. I do about a 30-40% water change every other week. I'm on Denver city water which is about 175 TDS out of the tap, but I also have RO/DI available that I use for my saltwater tank. Yesterday I used the API test kits and got 4 and 8 for KH and GH, respectively. My pH averages about 7.8 according to my Apex probe.
What numbers should I be targeting for KH, GH, and pH? What's the best approach to get toward those numbers? Should I do water changes with part (or all) RO until the hardness numbers come down? How do I maintain the right hardness and pH after that?
Thanks!
Larry
