What do you call super high nitrates? And how often and how much do you change water?

well for now i have the crappy nutrafin max test set so its not exactly the most accurate test set. and i consider high like 20 and above. However i just washed my test tubes, and water syringe really good and re tested, and now it shows 5 or less nitrates, but it still is higher than my nitrites. Just proves how accurate it is. I do a 5 gallon water change once a week.

Even N03 of 20 is not really high, unless you have SPS corals. Fish certainly don't mind. But you should get a better test kit.

What do you use for P04? Many of the cheaper ones do not measure accurately at the low end. Salifert or a Hanna LR checker work well. I used to think I had no phosphates or very low until I got a Hanna Phosphate checker.

Having said all that, one of my tanks used to have high nitrates (40+ consistently) and high phosphates (over 1.0), but I still did not have a cyano problem because of my MB7 dosing. It adds beneficial bacteria to your system which out competes cyano.

You'd be better off changing 10g of water every 2 weeks.

Thanks for all the input. I will be getting a new test set next week. I need a more accurate mag, all and calcium test anyways. Hagen six. I will deff be looking into that mb7. And really? You think it would be more beneficial to my tank to do 10 every two weeks instead? why is that?

You get a bigger vol turnover in your tank with 10 g every 2 weeks instead of 5 every week. Do the math.

Or think of it this way. If you changed 50% of your tank every week, or 100% every 2 weeks, which will provide a more complete turnover of your water? Of course that is not practical or recommended, but just wanted to use that example to help make the point.

Makes perfect sense. I will start doing that next time. Thanks for the advise!

could it be red slime?
