Overdosed trisodium po4

[Tony616]

Hi guys, I tested my po4 after work today and it hit bottom 0.00 with Hanna po4 checker.

I accidentally overdosed my 180 gallon with 0.5 po4 instead of 0.05. Stupid me always get these numbers mixed up. I retest with Hanna and it is at 0.52

Is there anything I can do? Should I do a huge water change? Or should I just wait for it to go down?

The tank is running fallow at the moment.

Thanks

Have you measured it to detect it that high?

Just tested again this morning (it's been 12 hr since last test) phosphate is at 0.19

last night was at 0.55 30 min after i dosed. I'm guessing most of it bonded to rocks?

Probably. Not a big deal at the moment. I'd keep monitoring it for a few days and see where it stabilizes.
