Figured I'd give you all another update. Lost several fish last week. Not sure what triggered the problem, but the only one who survived was Barry.
Sunday, got 2 new otto's and 2 new amano shrimp. Redid my CO2 reactor so that it is now outside of the tank. Works MUCH better than the one I was using. Also added a drop checker, and somehow, by sheer dumb luck, I had my CO2 right where it should be(4 dKh solution in it with reagent turned a nice green color after a couple hours). Also added a rather crude, but effective, way to basically do a partial shutdown of the CO2 reactor at night. Added a regular airpump, check valve, and control valve to a T on the CO2 line(after it's check valve). First night with this reactor, and in the morning the drop checker was turning yellow, not hinting, but full on yellow. The extra oxygen seems to help out a lot on limiting how much CO2 is being dissolved at night.
All my tests(NH3, NO2, NO3) are coming out at 0, and phosphate are between .25 and 0. I even took a sample in to my LFS to have them test it. Their first question after testing was if I took the sample right after a PWC, simply because of the results all being 0.
I also added some new plants, a corkscrew val, and another one that I constantly forget the name of.
