Phosphate Won’t Increase

[living_tribunal]

Well, the amount bound depends entirely on the concentration in the water, but with that caveat, yes. If it is stable at 0.01 ppm phosphate and you want to boost it to 0.02 ppm, then more will bind to the rock.

So if I’m at a stable 0ppm, would the nice slow and steady approach be to cut all lighting on fuge, feed heavy, turn off skimmer, and dose .02ppm a day and ride it out until my phosphates are consistently measureable?

Did you guys ever resolve your phosphare issue?
I'm wondering what happened. Did you continue to increase the dosing and did you have to plateau the dosing? Did the phosphate finally stablize without continued dosing?
Thanks for the info.

Sure did. Just a crap ton of phosphate dosing. You just need to spot check the phosphate levels every 2-3 days because the rock will bind quickly depending on how much you dose. Once it's bound, you just take it from there.

I'm actually going through something similar right now. I had a small gha outbreak. I was trying to maintain that perfect balance of overexporting the dying algaes phosphate and ended up exporting a little too much. This stripped most of the phosphate from my rocks so I've been having to dose phosphates again. I've been dosing about 20ml of neophos a day and will probably increase that to 30ml. For my tank, roughly 100g water volume, that equates to .07ml of phosphate a day.
