my phosphate levels are currently extremely high, my test kit goes to 5.0 and it is much darker than the kit reading for 5.0.
My system is a 150g tank with a Wet/Dry unit, I have a Aquac 120 Protein Skimmer (I would have gone with a bigger slimmer but space is limited) powered by a Rio 2100 pump, I have a Phosban 150 Reactor and a UV
I have done several water changes of 75g up to 100g with no effect on phosphates, I have used a product called "Phosblaster Super Nuker" and used an entire bottle dosing every night with no change in the reading. I have also used Chem-pure Elite with no effect.
I have taken a water sample to a local aquarium shop and had them test it and they get a very high reading as well.
Is it possible that the levels are so very high that these products are effecting it and it just hasn't become low enough to see it on a test? Is it possible there is something that could give me a high phosphate reading when they are not really high?
Also I do not have a lot of algae in my tank which I thought was normally associated with high phosphates.
My Bio-Load is:
Two Spot Wrass (L)
Green Chromis (2M 3S)
Blue Reef Chromis (1S)
Valentino Puffer (S)
Huma Huma Trigger (S)
Porcupine Puffer (S)
Yellow Tang (L)
Sailfin Tang (M)
Powder Brown Tang (M)
plus live rock and about 2" of sand.
Any suggestions are greatly appreciated.
