Hey, im a bit perplexed and need some help. In my last 3 systems I set up, i have been dealing with massive phosphate uptake. Last tank ran for well over a year and I fought dinos constantly from phosphate consumption, I shut it down because I just couldn't deal with that anymore.
I mention that it was over a year to get into the rock binding thing. I dosed multiple times a day for over a year and still never "hit equilibrium" so I'm not buying the rock binding thing in that situation. I had thought it may have been from the bacteria that was prominent in that tank, it was prodbio sunstrate sauce.
So this time around I went with fritz, tried and true. Im well over a month into this tank and the same thing is happening. Im dosing significantly more in this 75g currently then I did in my previous 200g and I'm still struggling to keep it above 0. Im currently dosing reef moonshiners phosphorus at 12+ml a day. Equating to somewhere around .06-.08 ppm.
I even dosed 24ml one day to try and buy some time, or to do some sort of "loading" dose. Under 24 hours later I still tested at .01ppm
There's no coral, no media, no significant algae in this tank.
What am I missing? Im so tired of living on the razors edge of a potential dino bloom, along with hesitation to introduce coral because my phosphate is swinging so significantly on a daily basis.
Im entertaining the phosphate binding thing in this tank but im just not convinced. Admittedly I used rock from my old tank, dry, that still had bio material on it it was dirty. My nutrients were sky high after the cycle because of the decomposing organics, but within 2 days the consumption was on full force. I went from 60 no3 .4 po4 after cycle to 5 no3 and 0 po4 within days after that.
The only similarity I have is the aquaforest rock. But I cant accept that either because I had a 45g for years not using aquaforest rock but using substrate sauce bacteria initially, that tank did the same thing for well over a year until it didn't anymore.
Its like theres something I'm doing that creates this. Part of me wants to stop dosing po4 and let the rocks have a chance to equalize and release po4 rather then constantly absorbing it, but id rather suffer through dosing then deal with dinos ever again. Dinos man.
my tanks prior to these never did this. Not anything close to this. It took a month of occasional dosing to maintain po4 then po4 wanted to climb and I went to the opposite spectrum of removal. What I would give to need to remove phosphate vs dosing it.
