Phosphates

Not really, most comes from food that you feed your aquarium, GFO is your best friend for removing it. Best to maintain around .04 ppm After all corals utilize algae within their cells and algae uses small amounts of phosphate to grow. But to much phosphate and it inhibits growth also. Generally you will get better color out of SPS when you can maintain very small amounts of it.

 

Its hight, but not a killer. I use Phosban to help get it back to lower levels. It hard unless you have a real good setup.

 

.25 is pretty high. .05 is considered the highest recommended level for sps corals

 

GFO is your best bet to lower phosphate

 

What food do you feed? A lot of food is high in phosphate. also where did you get your live rock from. cause if you got your live rock from a system that had high phosphate it can be absorbed into the live rock then leach out into your system

 

So, I got a tank with rocks that had some nitrates and phosphates in them. I started running a 2 little fishes 150 reactor with GFO on it and the tank cleaned up in a couple of months. It was quite impressive really. Nitrates in the 80 ppm and phosphates in the 0.5 to 1 range. I did weekly 20% water changes with that and now am at 5 ppm nitrate and virtually 0 phosphate.

 

Do you have a reactor?
