Thanks mnat...I took the sponge out.of the AC.tonight which in turn kinda clouded up the tank. I'm looking at the test results as I type and the Nitrates are still high. I'm thinkinf the sponge was holding them in so ill let the tank fikter and check in another day or so. I put another bag of carbon and a phos remover bag in there as well. ill take a pic of tbe tank when its a little more clear. I've been topping off with salt and the SG stands at 1.023. I think that's good enough for now. No diatom bloom or algae...fingers crossed.
