Bigfish's swim into the sea - a tank journal

Are you saying your p04 is that high in your rodi water?

I would except you have very high TDS, and likely source is rodi filters are spent or something isn't functioning properly with in ur rodi setup.

Do you have a tds meter, even one of the cheap ones from Amazon would help give you some kinda idea if your rodi setups doesn't come with one.

If your starting with rodi water with that much po4 your only adding po4 with ever water change and with rodi auto top offs.

Using gfo or LC to try to counter that is like trying to swim through the air. Solution would be tk address rodi water to get to zero TDS.

Once there I would dump all existing ato water and exchange it with 0 TDS water. Also plan for massive water changes.

It's also likely you would have tons of po4 inside rock structures that may leach for a while until things eventually level out.

1st step check rodi TDS and address it.

***Don't over dose The LC, trying to rapidly fix the problem.

Again address rodi water first so you’re not just adding po4.

I mentioned in my other posts I’m waiting for new resin my current TDS is at 1 ppm. Once my new resin comes in I will test again I fully expect it to be 0 ppm

I just didn’t want to wait and wanted to get an idea of how high my phosphates actually were around

Once I fix my RODI water I will test it again purely for any phosphate (my RODI water only) and report my findings. Then mix a fresh barrel of saltwater to 1.) do a massive water change and 2.) check my more accurate phosphate level with fresh saltwater and my tank water
