Phosphate reading is to high

[jserpe1947]

I'm getting a Phosphate reading of 2.0. In the last month I have done two water changes. The first water change was done on December 15th and was 20 gal. The second was done on Jan 10th and was 15 gal. Should I increase the amount of the water changes or is their some thing else that can assist in removing Phosphates. Also could Phosphates affect the growth of Coralline alage. Thanks in advance for your feedback!

Size 75 gal

What are your nitrate levels? Do you use tap water or RO water? Some tap water can have really high levels of phosphate. What is your bioload in the tank? How often do you feed your tank inhabitants? It will be easier to control if you find the cause of the high phosphate.

try some phos ban. worked great for me.

That is a high bioload for a 75 gallon tank. That is probably at least part of the problem. What are your nitrates? Do you have a refugium? Some sort of nutrient export will also help out.

what kind of bed do u have? from what i understand having a crushed coral sand bed produces a high phosphate level from all the food and detritus being trapped in the crushed coral.
