This is a quote from my local online forums:
Anyone else out there having problems with IO? I have read about a few people locally having problems with IO parameters....
Tonight I did a 20% water change by using a small hose to vacuum the gunk off the rock and sand. It did a great job at cleaning it up. After the water change I checked my phosphates and they were even higher than yesterday. I had some salt water still in my bucket so I did a test on it and the phosphate was just as high as the aquarium. Then I tested the tap water and it showed no phosphates. I take this to mean that my salt is the phosphate culprit. I thought Instant Ocean was supposed to be a good salt to use. Now what? Any suggestions?
