What about calcium nitrate?If you are concerned about potassium getting too high, I'd just use food grade sodium nitrate. Google shopping has several options.

What about calcium nitrate?
I began dosing today. I have a 64g (total volume) tank. I dosed 3ML, and got my NO3 up to 1ppm from undetectable using Red Sea test kits.
PO4 is at .01-.02
I feel like I actually saw a difference in polyp extension in my corals after a couple of hours. I may just be jumping the gun on that, but it sure does look like a difference was made!
So... Hw goes it?
This is week two of dosing 5ml a day. My beginning dosage got the tank up to 5ppm. It was holding at 2.5ppm but looks like it is getting consumed at a higher rate. Going to increase dosage. From two weeks of dosing corals have held some color but I think it will get better as nitrate is only 1ppm currently. I have noticed a dramatic difference in the rock work as all signs of algae is gone. It was such a difference that I have stopped testing for phosphate and have not had to add any gfo back in my reactor.
Are you using some sort of export method for phosphate that might have been nitrate limited? Like an ATS or macroalgae or organic carbon dosing?
I sure am ; ) I use organic carbon dosing. I also dose bacteria and run zeolite stones. There are only three fish in the system. I have always had this issue with my tanks as I have always used carbon dosing (i.e. Zeovit, RedSea NO3POX and Aquaforest). The nitrates would drop to 0 on test kit and the algae/cyano issues would start. Dosing nitrates seems to be helping with nitrate/phosphate ratio.
So... I tested my NO3 today and yesterday, and it said it must be higher than 64ppm... 2-3 days prior it was testing at less than 4ppm... I'm using a Red Sea test... surely that has to be incorrect.
I would STOP dosing and take some water to your LFS to get them to test it.
You should probably do a water change and immediately lower it. It will stabilize.
How long have you been dosing. I test 2x a day if I am dosing because I cannot get my readings stabilized as accurately as I would like.
