Phosphate 0.65??

[rkpetersen]

Sure, corals will grow with an elevated phosphate. They might even grow faster. If you want fast-growing brown and tan-colored acropora, let your phosphate rise to over .1 and keep your nitrate elevated too. If you want slower growth but with intense color, keep your nutrients low but not zero. This has been pretty well established imo.

If you are not having issues other than you testing it and saying that you have an issue.... I wouldn't go aggressively at this. I would just let my water changes take care of any issue in that size aquarium. Doesn't sound like you have an issue to me if your corals and everything are doing fine. If its not broke then don't fix it. Best advice I can give you. Chasing numbers will always get you in trouble.

If your phosphates are high and you have algae growing every where and sps have algae growing on the ends and cant grow due to phosphates then that's another story. JMO.

This
100%.

Yep, look at all those drab brown and tan acros in Richard's tank: https://www.reef2reef.com/threads/high-phosphate.237206/#post-2768749

Yes, because one specific person's experience is evidence that it works that way for most people.

A very long an interesting thread with a number of heavyweights.

It is worth considering.

FWIW, I'm just trying to help out the original poster. In the past I've messed my tank up pretty good chasing numbers and changing things too fast, and I don't want that person to panic because of someone saying "your phosphate has to be lower than X", because there are people out there whose tanks work just fine with phosphate more than X.

Bump help my po4 was going down I had it down to 0.07 and now it’s reading 0.33. I started dosing nopox and that helped since the gfo wasn’t helping. I do 3 5 gallon water changes a week and I just can’t seem to win this battle. I only feed the fish 2x a week and the coral 2x a week. I use RODI water from my aquatic life RODI Machine. Any ideas. I’m also lowering my alk from 11 to 8 hoping to have less acros stn. My alk is now at 9.6 with doing 3 water changes per week.i just can’t figure out where these po4 are coming from I haven’t dosed nopox since Monday because I dosed it and the power went out for about 2 hours and I had a bacterial bloom and that has now cleared up. I will say my water out of the tap is absolutely garbage if you fill a water bottle up it’s straight white and it’s so hard. But my RODI machine should take that all out right?

Are you able to test your tds coming out of the aquatic life RODI? its the 4 stage one?

I would eliminate that first, your weekly water changes might be adding phosphate.

 

[Camaro Show Corals]

I am not able to test tds but ill test the po4 on it, yes its the 4 stage twist in one

 

[Yikesdoris]

hello everyone, my phosphate level are at 1.0 what would be the best way to lower theses levels.

 

[Justfebreezeit]

Water changes and figure out why its that high

What are you testing phosphate with?
How fast did it go from .07 to .33?
You said previously your alk was 7.8 now its 11, how did that happen?
test you RODI water
