Seems to be a strange point to hang on to. The measurement he's getting is phosphate in the water column. My response is in that context as well. No matter the method they use, they will have to deal with leaching until they are at a level they desire. 0.7PPM is indicative of a tank that hasn't received appropriate water changes (for the size or equipment being used). Water changes are pretty fool proof, especially for mid-size and smaller tanks. Unsure of OP's tank size.Correct, but that is not what you actually said, what I was replying to was your statement that a 50% water change would bring the OP’s po4 lvl down to 0.35 which wouldn’t be the case….maybe a few 50% water changes would start to see a reduction.
Most don't have a problem being high rather they are low.None us have actually studied marine biology so for all we know, iodine and strontium levels could actually be the problem.
Our reference point is the coral reefs where these corals come from. Don't need a marine biology degree to match natural seawater. Many trace elements have been studied and their biological functions are known (to a degree). Other trace elements present have no currently known biological function. I'd recommend some more research.None us have actually studied marine biology so for all we know, iodine and strontium levels could actually be the problem.

What does trace elements do besides color?
You really should stop posting. I'm not sure you're not a troll, and here You've derailed this poor guys thread.I also read that there’s a little bit of uranium and seawater
Can you tell us a little about the tank? What methods do you currently use to export phosphate?As title says, I’ve been having Phopshates creep up and up with no luck on making it stop. Time for GFO? My sps are starting to lose a bit of color but still are growing and have good PE. Dosing nitrates as well and trying to get them above 10
Alk: 6 (raising slowly to about 9.5)
Calc: 410
Mag: 1455
PO4 0.7 (not 0.07)
NO3 6.0
All tested using Hannah testers
FWIW, my response to my interpretation of the original question would be:Wow okay lots to go through here
It’s a 4 year old 50 gal AIO Waterbox
I might say at an Alk of 6-dKH the corals might lose color or melt.As title says, I’ve been having Phopshates creep up and up with no luck on making it stop. Time for GFO?

You're still ignoring the whole point that the water is what is being tested and changed. Leaching phosphates doesn't change the fact that 50% of the phosphates that showed on the test (i.e. level in the water) were removed. That's fact, regardless of where the equilibrium is met and what leaches after the fact. You can only manage what you can measure.The point I was hanging on to was the point you made, not what you meant to say or should have said.
You said if the op did a 50% water change the po4 lvl would drop to 50% which is not the case, you then corrected yourself, which was good for those that may have followed your first statement and not got the results you claimed they should have gotten.
Trace elements are essential for biological functions within the coral and its symbionts.What does trace elements do besides color?
Not likely... Phosphate is often bound in the rocks.A 50% water change will knock that down to 0.35. GFO is going to impact your trace as well.
Maybe YOU haven't studied marine biology...None us have actually studied marine biology so for all we know, iodine and strontium levels could actually be the problem.
Completely OT but do they though? The actual scientific proof for that is fairly lackluster.They are keeping acros. Trace absolutely matters. Trace matters for all corals. Not to be a jerk, but you really need to gain some experience before making recommendations. I'd recommend listening and learning, then applying and experiencing before making recommendations.
I have in my spare time.Maybe YOU haven't studied marine biology...
