Ok ph in the old tank is 6.4 and in the new tank is 7.4.
I done full water tests on new and old tanks, new tank 0 ammonia, 0 nitrites, nitrates 15mg/l. Old tank freaked me out as it was 0 ammonia, 0 nitrites but 160 nitrates. As you can imagine im pretty shocked as I do a 20% water change once a week on this tank.
I want to get my oscar in the new tank as soon as possible. Would the ph change from one tank to the other cause lots of problems or would I be best raising the ph in the current tank to match the new ? How can I do this as ive not needed to do this before.
Sorry about the large amount of questions but its freaking me out a little
