Phosphate spike, need help/advice.

[BubbaBobba]

Hey everyone, noticed today that stylophoras and palythoas were closed up today and I decided to test my water. My phospate has spiked from .28 to 1.81(!!!) since I last tested 6 days ago. I'm not sure what could have caused this since I havent changed my daily routine and need advice on how to lower it safely and quickly.

Parameters
Salinity: 1.025
Nitrate: 21.2ppm
DKH: 10.7
Phospate: 1.81ppm(!!!)
Calcium: 420ppm
Ammonia: 0ppm
Magnesium: 1350ppm
pH:8.1
Nitrite: 0ppm

Any powder coral foods you are using?

 

[Mr. Mojo Rising]

i dose 5ml of AB+ daily and then do Reef Roids1-2 times a week.

what test kit and did you retest?

Hanna Checker, tested twice. First was 1.79 and the second was 1.81

Reef roids will definitely raise phosphates. As to whether or not that’s your issue it’s hard for me to say as I don’t know how much your feeding , test kit accuracies etc. to bring them down I use phosphat-e from brightwell . Read direction carefully so as to not over dose and remember to bring them down slowly over days not all at once . Good luck :smiling-face-with-sunglasses:

Are you holding the button down to let it count the 2 mins I didn’t do this and learned to hold down button to let the checker count down

My Hanna Phosphate checker only goes as high as 0.90. It blinks 0.90 if higher. GFO helps or Coral Snow but it is expensive

Thank you! Going to give this a try, for now I will do a 20% water change until it arrives.

I’d definitely cut down on reef roids if not just stop using they definitely increase po4 a lot just use ab+ and maybe push it to ever other day and see what that does I stopped dosing both because of increase in my po4 and gha growth

huh, interestingly enough I just had a pretty bad hair algae outbreak last week.
