Phosphates

[Fishingandreefing]

I am currently having extreme high phosphate, it was at .90. Did someone say don’t focus on the number?

did a 40% water change. Running chemipure and phosguard now. It’s been a few days and it dropped to .77 now.

according to phosguard instruction is to pull them out in 4 days? Anyone?

will do another 30% this week, don’t want to shock it too quick.

Maybe more than .90 since that’s the max it measures, omg.

seachem phosguard does not require reactor, just place it in a mesh bag w high water flow

That’s what I am doing. Per instruction, remove them after 4 days and replace it with new batch? Only last for 4 days seems a little confused.

0.15 Phosphate is not really that bad unless you are seeing issues. I usually change out my GFO at 0.25-0.3.

R u testing PO4 levels after 4 days or just replacing it?
if it's lasting only 4 days & no longer removing PO4, then it means either not enough Phosguard is being used or there's a lot of PO4 so the Phosguard is spent and no longer able to absord PO4. If PO4 is high, then Phosguard may have to be replaced often in the beginning. But like Bluespottedjawfish said, 0.15 isn't that bad and if u r not seeing adverse conditions, may want to leave well alone and just maintain current levels?

It was dropped from .90 to .77 with the added chemipure, phosguard and 35% water change. Now 3 days later, it’s back at .84. I will test it again tomorrow and most likely add more phosguard.

note: chemipure was added 100g dose and phosguard was added 75g. My system is 150 including rocks.

I didn’t want to add too much to shock the system. Any other suggestions are welcome.

is ur tank new or mature & r u using a skimmer?... If PO4 is increasing after 3-4 days, then phosguard is spent and needs replacing. I'd change it out & each time gradually increase the phosguard amount while monitoring level of PO4 reduction every 3-4 days. Whatever u do, don't lower PO4 more than 0.50ppm/24hr period.

Phosguard didn't work for me so I switched to Rowaphos in a reactor & happy w results. I use half the recommended dosage, folks do the same with GFO. Reduced feeding, esp frozen food & nori will also help reduce PO4, fish will survive on 1x/day feeding. My PO level is 0.13-0.15 w no adverse conditions.
