![]() Matt, did you find this article? The article is regarding elevated nitrate, but does talk about the effects of alkalinity with nitrate and photosynthesis too.

Anyway, I'll spend more time with it and wrap my head around it later. Thanks! |

![]() Ok, tests as follows:
NO3: .2ppm PO4: .07ppm GFO has been off for 24 hours now. So, yesterday I dosed 1ppm NO3, the tested levels rose yesterday and had fallen again today. Tough to say the effect its having on PO4 because I've been running GFO and only recently shut it off. So, 24mL solution (2ppm NO3) dosed today. |

![]() Ok, so this is interesting:
1.5ppm NO3 0.01ppm PO4 And the water is cloudy! So, as soon as the bacteria had enough NO3 they went crazy. I tested PO4 twice. First time showed as 0. Second showed as 5ppb phosphorus (.015ppm PO4). I'll let the bacteria bloom pass, then I'll resume dosing NaNO3. |

![]() PO4: .024ppm
NO3: Didn't get home until super late. I don't know about anybody else, but I can't get a very good read on the Salifert test without sunlight at my back. Artificial light just doesn't do it for me. My skimmer pulled a half a cup of the nastiest crud in the last 24hours! Very thick and smelly! Can't really comment on how things are looking as the lights were off when I left this morning and were off by the time I got home. Both anemones look deflated, but that's not necessary abnormal. Overal things are still coloring up from the bleaching. Steady improvement over the last few days. |

![]() This is interesting as I have the exact issue zero nitrate and phosphate always .03-.07 by the way Hanna is your best bet for nitrate test kit screw the color matching game.

It feels so weird dosing nitrate.... I've been so proud I've had undetectable levels for the last year, but frustrated with the amount of cyano I've battled... It makes sense. Bacteria, corals, fish, you, me all need Carbon, Nitrogen, and Phosphorus in different ratios. The ratios are different depending on the organism, but it's a triangle. My reef was deficient in Nitrogen. Some are deficient in Phosphorus or Carbon. If you feed the bacteria enough of all three they flourish. I'm pretty sure the cyano was doing so well previously because it was getting plenty of carbon and phosphate, and for nitrogen they are particularly good at "fixing" atmospheric nitrogen.

![]() The lights in the garage seem to make it easier to read the Salifert NO3 test.
NO3: 2.5ppm PO4: .03ppm Yesterday I dosed 1ppm NO3, today was none. Seems now PO4 is the limiting nutrient. NO3 is the highest I'd like to see it. I'll stop dosing until it gets below 1ppm. Lets see how long it takes. |

![]() Are you running rowa or something to absorb phosphate? or at this point just relying on the nitrate to help keep phosphate low .
