Phosphates and growth

I have always tested at .1 phosphates and 5-10 nitrates. I am thinking of getting a phosban reactor to get it to 0. Am I right in thinking that .1 is enough to retard coral growth?

it is possible cause if you are testing .1 its prob a lot higher cause of test inaccuracies and the use of phosphates by nuescence(sp) algae

I have no "nuescence algae"

i'm sure corals need phosphates to grow too (part of cell membranes, dna backbone, etc). if you have a canister filter, you could throw some phosban in there until the levels come down. i think some frozen foods have a lot of phosphate in them too. i guess that doedn't really answer your question, other than i wouldn't spend the money on a phosban reactor.

I personally would not worry about it - those are low levels and should not have any negative impact on the growth of corals.
If it bothers you and you water perfect water chemistry: increase the frequency and/or volume of your water changes, get a better protein skimmer, feed less, add a refugium, etc.
