phosphates are high

[nano man can]

i have a 20 gall nano and my phosphates are really high and im getting a lot of brown algae how do i get em down?

[gabbeyshell]

what type of h20 are you using?

what type of salt mix are you using?

 

have this same prob-started to get hair algae, ro/di water was 0, io salt mix before entering tank is .2. might want to check into that.

Assuming your cycle is was complete the phosphate could come from:

1. Overfeeding

2. Carbon needs to be changed

3 Poor water quality (tap water)

 

Do a 20% water with RO water and cut back on feeding... don't starve the tank, but use a little less food at each feeding (assuming you are adding food or phyto). Change the carbon if it's more than a month old. You may also want to use a higher grade of carbon such Black Diamond or Chemi-pure. Consider using phosban to remove the phosphate. A refugium or adding macroalgae to the tank will also help with this problem.
