[smokeypea]

I am sorry to appear very stupid, but i am new to this, i have 20 gall tank , peguin 150 bio wheel and one airstone, i just got a Aquarium Pharmaceuticals freshwater master test kit and not sure if the readings are okor not,, had tanks since 28th april... PH 7.2 AMMONIA 0 PPM NITRITE 0.25 NITRATE 5.0 I hope i did the test correctly, thanks for any help, also do i need to put maybe another airstone in for oxygen or not? thanks.

Your nitrite levels could be a little lower but other than that it is ok. The pH might be high but that entirely depends on which fish you keep.
