Thanks for all the good advice. I did say in my last post that I was looking at the ro/di units. I am definately not solid on using my current filter. I want my tank inhabitants to have the best water I can give them.

Everything is happy and my water tests are all perfect except for a little Nitrate(10) and some phospate(1-2). I suspect the nitrates will go down as the deeper parts of my sandbed have time to breed more anarobic bacteria. I am surprised I didn't see a spike with how much everything was disturbed.
