Just tagging on instead of starting a new thread. I too was/am battling hair algea, but I know mine was from lack on Maintenance.
Did a large PWC
as well as manually removed about 90% of the visible algea. I have been focusing on nitrates which seem acceptable 0.2-0.4 right now. After doing some reading I am now checking my PO4
which is likely the culprit. Last night the tank was somewhere between 1-2. I say this because on the low end P04 test(0-1) it was defiantely over 1, but when I did the high end P04 test(1-5) it did not register. I did check my RO
source and it is reading 0.
1. Assuming 0 PO4
is ideal what is an acceptable level before you will have a problem?
2. What is best method to remove it? Right now I am using PWC
and have another planned for this weekend (30g).
I have seen products called a phosphate sponge (granular subsatste that I assume you run like carbon), but not sure if they work.
Now I see discussion about Phosban reactor. Not sure what this is or if it is required. How costly? Can someone send me a link?
So far Corals have not been affected and are even looking much better after the maintenance last weekend.
