My ninety gallon been running for about 2weeks. I've done a couple (10 gallons total) small water changes. Most of the water I took from the person who had the tank before. I have a shrimp, Koran angel (only new fish, the rest came with the tank including live rock), Clown, couple of snails and a starfish. All the water is testing perfect except the P.H. which used to be 8.4 last week but now is at 7.4. I was planing on doing a 10 gallon water change tomorrow what do you guys think. Also I have a skimmer and 25 gallon sump underneath.
