Tank won’t hold p04 help!

[Ling_Thing]

So ever since Brightwell changed the concentration on neophos about a month ago without me knowing the p04 went to 0 and now I cannot get it to hold p04 at all! I’m dumping 200ml a day into my reefer 450 which is equates to .095 ppm and it’s all used up within a couple hours. I know phosphate binds to rock and sand but something just seems wrong here. My n03 stays around 2-4 where I want it and I’ll have to dose neonitro every few days to keep it there but I can’t get a p04 reading to save my life with my Hanna ulr and regular Hanna phosphate high range. Should I stop dumping in a bunch of neophos daily? I’m just nervous cause every since they hit 0 thanks to Brightwell, my acros have suffered and I can’t bring them back but there not getting any worse if that makes sense.

I use this to keep my phosphate up.

Could make a stock solution of 2.5 grams to 400ml water and add ~.01 ppm per 1 ml of this solution.

I actually just bought some trisodium phosphate from loudwolf so I’m gonna mix up my own solution tonight but can I use your recipe or is tsp different from monosodium strength?

Use a little less, 1.93g should make the same po4 concentration.

Fauna marin Ultra PHOS 0,04 a novel compound granules, which phosphates and yellow substances are safely removed from the aquarium cycle.
A unique feature is the safe use of UltraPHOS004, since the PO4-value can not fall to 0.00. Therefore Ultra PHOS 0,04 is safe, while extremely effective.
