Hanna phosphorus checker result

[kevensquint]

So in a tank with a med/ high bioload. 160 gallon with 3 Tangs, a clown trigger and bunch of smaller fish. The PO4 checker always reads 0ppm. I tried the phosphorus checker which shows 1ppb. Is that possible? According to the conversion I found that is 0.003 ppm. I would love some PO4 to boost coral color a bit. This is ridiculous.

It's certainly possible if you have sufficient phosphate uptake/export.

Jeez..maybe a few more fish then.

Sounds like a plan!

I had a tank like that and I stopped the skimmer during the weekends. Also I keep the filtersocks overflowing for some time.
