Help phosphates through the roof!

Hi so I'm new to the hobby and currently curing my dry rocks for about a month and a half. Ammonia is 0-.25pmm (chemical test kit colors are so close together) nitrite is 0ppm and nitrate is a a little higher than 0ppm. So I was going to finally set up my DT but I tested for phosphates were 1.99ppm! I decided to hold off and do a water change but nothing changed. Is that high of phosphates going to cause algae issues? Not worried about corals since it's a FOWLR tank. Any help or advice is appreciated.

 

your new tank will go thought various levels of algae growth. you can use phosguard in a reactor to help control it.

 

Yeah I have a gfo reactor bought and ready and was going to have that running until the levels are under control. Another question I have is that I accidentally bought a freshwater LED light strip instead of saltwater. Is there a difference in color/intensity that will make algae grow faster (again not worried about corals since it's a FOWLR tank) or bring the color of the fish out? Debating on returning it for a marine light. Thought?

 

there is a chance of that yes, if im not mistaken fresh water lights tend to have a higher "red" spectrum to promote plant growth. but in order to be 100% sure we would need the specs of the light in question.....
