Lets talk phosphates

[bluesox68]

Ok so my tank has been running at my house for around 2 months and I am very happy with the progress. I have been able to fix a bad flatworm issue and just now the tank is starting to look really nice. What lives in my tank now are good clean up crew, cleaner shrimp, blood shrimp,serpent stars and yellow watchman goby The tank was filthy when I first got it.


Problem.


I have very high phosphate levels so for that reason I haven't purchased any fish. Again my tank was very dirty when first purchased but since then my levels are getting much better. I have removed the filthy dsb from the fuge and been using phosgaurd. The rest of my levels are fine and I don't have an algae problem or anything? I'm assuming the last owner used tap water so I do expect phosphate to leach from the lr but that will end with water changes right?


Question.


What harm can phosphate do for my tank and could I safely add fish soon?
I don't have the test in front of me but 2 weeks ago the phosphate test turned the water blue instantly without shaking it and as of yesterday its just a light teal almost yellow, Hopefully that makes sence lol.

Anyways any advice would be great Thanks
