Water changes for a 90g

[Krish]

I guess I just do large frequent ones

LOL...The thing I like about smaller frequent ones is you don't have to be as particular about make up water. 10 gals of "make up" water added to a 90 gal tank won't affect much if the temp is off a bit or the ph hasn't adjusted completely before adding it to the tank.

I usually do about a 30% change every month. I have not had any problems with phosphates from the trash can at all and I got all the plumbing pieces from home depot. I just went in the store with my pump and went through the bins until I got it hooked up to a garden hose.

Jetaero: Just for clarification. I do not pump SW into a septic tank. I have a seperate system for SW. Yes it would cause problems if it was put into your homes septic tank system.
