20 gallon tank
I did a fishless cycle, and was testing with a liquid test kit, not the strips you guys hate. After the cycle was done I added 3 fish at first, 3 more afrter about a week. I've had fish in the tank going on 3 weeks now.
6 small (maybe 1 1/2 inch.) Tiger Barbs
Results of today's tests:
8.0 pH (has been a steady 8 since about the 3rd week of cycling)
I should note that the color of all the barbs are bright once again. I've notice this before. 2 or 3 of the smallest barbs will have very poor looking color, then later in the day they all look bright. Also, despite having poor color at times the barbs are still very active in the tank. They don't act sick, they just look it.
