i set up my 44 gallon bowfront december 25th and i heard that if you used a filter from your old tank in your new one it would shorten your cycle. i done that. everything is in the safe zone except my p.h. i need it at about 6.8-7.2 foeer my discus. should i wait for it to level out on its own or should i try to lower it myself. i do have aquarium salt and water primer. what should i use to lower it? i heard that aquarium salt works well.
