Ultralith question , OPINIONS PLEASE

[atcman]

I have been using the system now for 3 weeks and am happy with results so far. I have a 120 total volume system. I am at 500 g ultralith and am now dosing 1.0 ml of BIO and MIN each day. I have no films indication overdosing. My water is clear and my glass is only scraped every 3-4 days now, Good sign so far. Here is my question. My phosphates today read 0.19 ppm. They were 0.40 at one time,. I have hair algae over many rocks and one aco. Over the past month , for sure since being on ultralith its hasnt spread. I am running Ultra carbon, and Ultra Phos in 2 phosbane reactors in series in my sump/. People indicate that you shouldnt use ultra phos while on the system , Idont see a problem as I am trying to get these levels down. What is so bad about running ultraphos with the system. I think phosphates are just leaching out of my rocks and fueling the GHA . Over time I think my levels will drop. Getting frustrated.

Thanks
Gerad
