I usually use a liquid test kit, that reads my phosphates at .02 or .03. I got a Hanna low range phosphorus checker, and it read 57 ppb which converts to .057 ppm. Is that high?

You are reading it wrong if you have the HI-736 which reads in ppb of PHOSPHORUS, not phosphate. If you have 57ppb of phosphorus, you actually have 0.175ppm of phosphate which is very, very high.
The formula to convert the reading on the ULR checker to ppm of phosphate is [ULR Reading] * 95 / 31 / 1000 = PPM Phosphate
BTW thanks guys. I added a zeovit reactor (which is still cycling) to my tank not long ago, a removed my GFO reactor. I was getting some cyanobacteria in my frag tank (which is attached to my main system) and thought it was just the zeovit cycling. I tested phosphate with my test kit, and it looked like .03, but colors on some of these kits are tricky to match up, which is why I bought the Hanna meter. I went ahead and put my GFO reactor back online, which will hopefully pull the phosphate down to a more acceptable level. Does anyone know, can zeovit reactors leech phosphate during cycling?
yesI have a Hanna 713 phosphate checker and my phosphate is at .57 is that high
I missed a zero....sorry, I meant to say .05 - .1, but with that said, in my early days of this nano my war coral sustained HUGE phosphate swings....I literally had "1.0" ppm couple times. But it usually was spiking up around .7 daily....took me awhile to get the nano under control. lol. He also grew (somehow) inside a giant patch of GHA that is all gone now.Mine reads .57 and my war coral is dying
It's driving me nuts. I'm using gfo and phosphate pads and water change every 3 days.
