Help, to much phosphate

[remi010]

Hey,
I am busy making my reef tank ultra low nutrients. There is quite a lot of phosphate in it. It is released faster from the living stone than the phosphate remover absorbs. I use 250ml rowaphos at 300 liters every 3 days. Thats a lot!!!
The next day I measure zero and after day 2 it's rising again.
What else can I do? I also heard about ATM Green phosphate remover, does that work better?

chaeto will get rid of it.

I use phosphate Rx and a filter sock to catch the bound phosphate. Does in the evening and remove filter sock in the morning.

water changes, gfo, carbon dosing, chaeto, refugium, fewer fish, lighter feeding are all tactics that will result in lower nutrients.
on a side note, being there are no system details to go from or experiences mentioned i will treat this as if you are absolutely new to the hobby. ULNS is a risky way to run your tank for a beginner and if done without the proper understanding of what ULNS really is (it isn't just depleting your nutrients to undetectable and calling it good) will just result in a dead tank.
again, i have nothing more to work off other than your start date so no offense intended, i'm just trying to avoid you issues.

My system is now running 1.5 years. Have always had some problems with phosphate.
I'm working on it for a week or four now.
I follow the probiotic method of aquaforest, my water values are as follows;
Ca440
Mg 1340
Kh 7.6
No3 1
Ph 7.9
I2 0.05
pottasium 420 ppm

one thing aquaforest does very well is offer products that are "carbon enhanced" so by design they reduce phosphate and nitrate. the probiotic salt is completely geared to that goal and if you were to simply add their probio S and NP pro i'm very confident you will reach your goal numbers but be aware, if you're not careful surpass them to a nutrient deficient system.
i have had many problems along the way with aquaforest but the one i certainly didn't have was nutrients especially with the probiotic salt. i'm by no means an expert regarding aquaforest as i opted to switch out because it did exactly what i was warning you about... drove my nutrients to dead zero and flattened a lot of my acropora.

Are you feeding foods?

Why do you think it is coming off the rock?

I feed 1 block Dutch mysis a day, sometimes little bit of dry food. far too little for my fish stock. For this I turn with triton and had no measurable phosphate. Then I added po4 + for a longer period of time. Furthermore, I do not have any dead animals or the like in the tank

Have you any other suggestions?

If, for some reason, phosphate was very high in the past, then yes, some will be on the rock and you'll need to pull that off as well as what is in the water at the moment, if you want to lower it.
