No livestock right now while I am experimenting. When I can get some test strips I will test the tank. Are there any test strips that test more than one parameter kinda like for a pool. I am not too worried because I have had the same gravel in a 20 long plant tank and everything seemed ok and I had ghost shrimp. It was ok untill I got too busy at work and did not do enough water changes. Today I added DIY hood with 2 x 26 watt compact flourescent. And compressed CO2 but my CO2 regulator died shortly after getting it started.
