Phosphate risen to 0.15 in two days

[spamvicious]

My tank has just finished cycling in the last couple of days. Six weeks from start to now. I tested the phosphate on Sunday and it was 0.02 today it’s 0.15.

The tank has started its ugly phase with what I think are dinos. I left it for a couple of days but yesterday I suctioned some of the algae off the sand and removed it, I ran the water through some filter floss and put it back in the tank.

I also have some filter floss in the side (it’s an all in one) I’m changing every day as it goes brown straight away from the algae.

I have two small clown fish and some soft corals. Everything is fine in the tank but wanted to see if I had done anything to cause the rise in phosphate. I’ve ordered some reef zlements all in one as my alk is only 5.8.

what test kit did you use?
Did anything die in the aquarium? is this a new system or established?

I'd just keep watching it once or twice a week.

As I said in my post it’s a new system, six weeks old. Nothing has died. I used Hanna testing.
