Quick question re: water change
I want to do a PWC
but don't know if I should vacuum the gravel yet. Ammonia=<.1ppm, nitrite=0ppm and nitrate=>5ppm pretty steadily for the past few days. Also concerned about sucking up any of the babies, but I assume if they are fast enough to avoid the larger fish they will be fast/strong enough to avoid the python vacuum.
36 gallon bowfront w/all fake ornaments, Eheim 2213 canister filter, one sub heater (have a hanging heater for backup), and a 4" airstone.
