*nods* this is what I have done so far, changed the media in the sump filters, 2 50% water changes seperated by 2 days, the nitrate reducer into the water, cleaned and made sure that the skimmer is doing its thing happily, and left the substrate alone after the first time I cleaned the base, realising I released a ton of bad stuff when I stirred it all up

. I am going to do another water change tomorrow , probably another 50%.
Ed I was looking into getting a Ro/di unit but the deal I had on the reef formum fell through though the guy not responding after agreeing.
I do plan on setting on up in the garage for filtering my base water.
