I bought it stocked, possibly overstocked with a 6" tiger oscar and three 4" Gromneys. with the move (from me buying it) it was a complete water change. I also purchased a new canister filter but continued to use the original hob
filter and still use it.
Had it for about three weeks, within those three weeks I did one partial water change at about 20%. Then I moved :/ drained 80% of the water for the move and transported fish in 5 gallon bucket. The large fish lived there for about a week. We did a pwc
at about 50% at the new place and switched from gravel to play sand. Then I donated the large fish to a new home and got the ABNs and snails. I tested water last night: ammonia and nitrite were 0 and nitrate was 15ppm. So I planned to do a pwc
today for the nitrates.
