Hello everyone, I've had the tank running for a year and I had a crazy high Phosphate 4 months ago. Hannah checker did not even read it as it was royal blue.(200+). Started running gfo and made water changes weekly. It got to a readable amount and ive gone as low as 40 on the checker but im...

The weirdest thing has been going on while testing. So I have the hanna phosphorus ULR and the Phosphate readers. So I know they have a conversion chart for the phosphorus and for some reason I had a 200 plus ppb reading last night. So i was like no way something happened while testing. I said...

I received some ICP results that said my phosphorus might be limited. I do not run GFO and I feel like my refugium has been struggling slightly also recently. My nitrates have been steady between 4-6 ppm, but it seems like phosphorus could be a limiting factor. Should I start dosing Phosphorus...

I often wonder how wild reefs are able to grow and thrive with such low levels of dissolved nutrients - namely nitrates and phosphates. I have an SPS/Acropora dominant tank and I maintain KNO3 solution on a dosing pump just to keep the corals alive - I try to maintain nitrates up to 5ppm...

I'm currently battling what I thought was Dinoflagellates. @mcarroll has ID this for me as Chrysophytes. Here is a background on my tank and where I am now. My tank build thread https://www.reef2reef.com/threads/4-years-old-and-just-getting-started.302988/ Total water volume 160 gal. I...
