Good evening

So i purchased a hanna ulr phosphorous checker and got a result of 185 (.56ppm) how bad is this in a tank containing softies?
A tad high for the typical LPS & SPS systems. Some would say it is way high, but I have seen plenty of large old systems that look gorgeous at what most consider "high" nutrients. If the tank looks good and the softies are happy, I am not sure I would do too much different. You OK on algae growth, etc? It really depends on your goals with this system.

If the system (or microbiome) has been running at these levels for a while, you'll need to be super slow and careful about bringing levels down. Much more damage and risk comes from lowering than from raising nutrient levels.

For comparison my softie tank reads out at 4. I have difficulty phosphates and nitrates up, though. Just add a little gfo to start bringing it down, and a water change to boot.
But like ScottB said, start really slow.

My Hanna ulr phosphorus reads 13 ppb, I'm not sure where that sits in the grand scheme of things, I'm also slowly winning my battle with GHA.
13 X 3.0661 / 1000 = .04 of phosphates which many consider an ideal level

Keep testing. Your rock is a store of phosphate. This is not a bad thing but a natural thing. As the GHA subsides, don't be tempted to go below your present level. Be patient. Go slow. Keep testing.

If the GHA takes of growing again, then it will be doing a lot of the PO4 absorption and you can be a little bit more aggressive. Just go slow on PO4 removal or else I will see you in the dino thread.

Thanks for the reply, I try to keep the removal to a minimum, I do manual removal of the GHA and water change of 5 gallons a week, my tank is a 75 gallon

That sounds good and won't get you in any trouble; I assumed you were using GFO. GFO is great but must be used with great care, attention, and water testing.
 

How do you run activated carbon on your reef tank?
