Phosban-reactor with Rowaphos question

[Delphinus]

It still did feel moist.

Ohhhh the REACTOR instructions suggests the minimum of 250ml. I didn't even think of that. I was just reading the insert that came with the Rowaphos.

I just get to thinking that having the flowrate of a trickle isn't ideal, it doesn't fluidize the media at all. So maybe the trick is upping the volume and the flowrate and going from there.

I'm not sure if 0.25ppm is enough to fuss about? I don't have any algae problems but I am having problems with SPS receding, so I'm trying to attack the variables I can think of. NO3 is a little higher than I would like, ~10ppm, but not enough to explain systemic SPS failure. I'm guessing the PO4 should be addressed so that's why I dusted off the ol' reactor and got it going again.
