po4 instability

[Miami Reef]

I don’t think it is unstable. I think you just have high phosphates, probably stable around 1.0 ppm. You are dosing too much lanthanum and plummeting the PO4. Then PO4 leaches out of the rocks to re-stabilize at 1.0 ppm. If you continue with lanthanum, do it slowly as @Miami Reef suggested and over a long time. Eventually it will come down, and your corals will be happier with the gradual decrease.

Read through page 2. His phosphate was only at 0.16 the whole time. :)

Decimal points are very important.

Bro. Seriously?!?

This is from the first post in this thread:



Then i responded asking for clarification:





Then you replied to my quote confirming that it was over 1ppm….




If your phosphates are just going from 0.07ppm to 0.16ppm, then that’s nothing to worry about.

sorry, yea i meant it goes from 0.08 to .16 when i started dosing lanthanum it was at .32

It wasn’t confusing. It was wrong. Twice in different words.

Done here. lol

yea stupidity on my part...but im still worried about those changes. i want to start keeping acros and am having trouble with sps(killing acros and cyphastrea). Is .16 to high still up from .05-.08?

0.16ppm won’t kill them. You can lower PO4 if you want, but try to look for other causes of death.

They need strong lights, powerful flow, and clean water (activated carbon and skimming helps IMO).

Phosphate and nitrate are nutrients. They are helpful in some amounts. They shouldn’t be the cause of death.
