PO4 at .50 .. Why?!

[Jhuneke]

Ok so I have a giant fuge full of chaeto , took my reactor off a bit ago to put on seahorse tank.. So I thought it might go up slightly . But I have zero nuisance algae. So I'm confused. Shouldn't I have an outbreak at this high ppm?
Btw.. Just did back to back 20% wc this week so I'm sure it was WAY higher.. And I do rinse my frozen food as well :/

you feed to darn much?

Did you retest? Possible false read? Test with another test kit.

Maybe because it's a huge myth that high PO4 causes algae and is bad for coral health.

I have a high po4 I only see it affect color of coral

Ya.. I retested , it was accurate. I have been having issues w Lps lately .. Have had quite a few pieces dying. Literally popping off the skeleton ;( mainly lobo amd wellso ( and a frogspawn ) so been testing with everything in normal range aside from po4 . It's so pissing me off ..
Could this level cause that kind of issue? I had a BTA touching a rock Nem and thought maybe allelopathy ..
Now I'm not sure.
Try not to feed too much, and rinse food.. But cuc IS low since they seem to die off a lot in my tank ..

Could you provide some information on this? My understand is stability is key.

Dirty

Thanks Bean.. Lol short and sweet... me .. Not YOU! Is it dirty enough to cause Lps to literally peel off skeleton and float away? Have a wellso that did that ( among others) that has been alive on my sandbed for 10 days.. Weird..

Agreed, I dont think the phosphate are the issue at 0.5. The coral issue could be a toxin in the water you cant really test for with hobbyist kits. It could be from a little coral to coral chemical warfare. Carbon and a water change can help with that.

Also, did you test your saltwater and top off water for phosphates before you added it to your tank.

PS - If you are running carbon, some activated carbon have been known to leach phosphate too.

Unfortunately water changes will not help phosphate much. Most of the phosphate in our home aquariums is bound to all of the aragonite in the system, only a small percentage is free floating in the water. You need to use GFO to remove the phosphate (or similar method).

I've watched the video from Richard Ross and he's obviously a smart guy with a lot of education and experience. But, in my own experience, phosphates are usually one of the culprits to a deteriorating tank. He even states that there are many factors involved and he does not know how his high phosphates come into play in the overall big picture. Since it has been documented that phosphate inhibit coral growth I think it's worth keeping an eye on it.

I'm not sure if your high phosphates are killing your coral but it probably isn't helping them. Just remember if you're going to try to lower your phosphates do it slowly, massive changes in your current water parameters will likely cause even more problems. Also, corals don't seem to like high doses of GFO.

You should check your equiment, I had something similar like that happen to me. Had everything from wellsos, fungias, clams etc die on me, only to find out after I took my tank down that the impeller on one of my return pumps was cracked and rusted.

I did just add a bunch of aquamaxx ROX carbon, wonder if it's leeching ?

This has been my experience more or less. When was your last p04 test and what did it test at?

 

[Jhuneke]

If you're asking me Andy.. Dunno and dunno lol I rarely test it .. Since I never see algae etc . Been too lazy I guess
