No ammonia here, Just using the Stability...
Already have ammonia levels - or well, have had. Last night water read as follows:
Ph. 8.3 - 8.4
Ammonia. .50ppm
nitrite 0
nitrate 0 (had a darker tint yellow)
Have also squeezed in pre-filter sponge from other tank. Im hoping by Saturday I'll see some changes. I shake the bottle like no other after each capful - looks like as talk about 'skim milk'
