Phosban media replacement

[Delphinus]

1-2 weeks! Just curious, have you actually tested your reactor effluent with the photometer and you noticed a difference in the levels?

I'm not testing fanatically anymore.. but I noticed my reactor effluent was 0.0 for about 2 days then after that it started to climb. So now I'm wondering now if it wasn't precision error (ie. the "to within 0.04" thing) after all, although I still think 2 days is awfully fast for phosban to exhaust itself.

My Reef consistently reads 0.01. My Trigger tank reads anywhere from 0.075 to 0.25, depending on the age of the RowaPhos. The difference between the two tanks in relation to this? The Reef has hair algae and multiple types of macros and the Trigger tank’s algae is minimal. I think the two tanks may have similar phosphate levels,....just that the phosphates in the reef are primarily in the alga, and the phosphates in the Trigger tank are in the water. I stopped using RowaPhos on the Reef about 2 months ago because of the consistent 0.01 readings. So far, so good. The Trigger tank RowaPhos gets changed out every 4 to 8 weeks. It’s a challenge getting that one below 0.075.

Cheers,
