Is 0 phosphate a problem for 1st corals

[johnj]

Iv got to get my first corals in morning but my po4 is 0.00 on Hanna checker, most iv had is 0.07 but did water change and put new floss and carbon in sump few days ago! Will the elegance coral and green Star polyp be ok in this low po4 ?

If your Hanna checker is based on ppm . There are still ppb phosphate in your tank. Don't worry if you didn't put any phosphate absorption material in your tank.
My tank is also read as zero.

Green Star Polyps will be fine. The Elegance Coral will appreciate some P04 as it builds it’s skeleton. Feeding your fish more with dry/pelleted food will raise P04 slightly when you need to.

Thank you does carbon lower po4 because mine has dropped little since putting new carbon in socks and changing filter floss. I don't run gfo/rows phos in tank. Just big skimmer and nitrate block and socks and sheet of floss over socks
