| I have a 6 gal nano and my sps haven't been growing like they should. They look heathy with good color and polyp extension, just not growing. I did some testing and found my phosphate to be 0.25. Would that be what's stunting the grow and can I get that down through more controlled feelings and water changes? |

what are the rest of your parameters? I would say yes that could be what is stunting the growth, but lets take a look at all of your parameters. ------------- http://utahreefs.com/forum/forum_posts.asp?TID=53856&title=annes-65g-rsm-reef" rel="nofollow - RSM 250 Reef |

I would also say yes , .02 good, .03-tolerable, .10-critical, .25-growth is stunted. When PO4 is that high it can directly inhibit calcification by corals.
"lets take a look at all of your parameters"
I agree.
"can I get that down through more controlled feelings and water changes?"
Maybe, problems involving phosphorus and subsequent algae growth can be among the most difficult to solve in a reef aquarium, especially if the live rock and sand have been exposed to very high phosphate levels, after which they may be acting as a phosphate reservoir.
Allowing the pH to drop into the 7s, especially if it drops low enough to dissolve some of the aragonite, may serve to deliver phosphate to the water column. ------------- Shaun American Fork "Would you leave a dead cat in your kitchen till tommorow?" Builderofdreams |
