Canadian Aquatics. I think his name is Patrick. He carries potassium nitrate and potassium phosphate. He'll need a photocopy of your driver's license and you have to declare what you are using the potassium nitrate for. Required by law because it's a controlled substance.

My tanks is just over a year old so I'm pretty new at this. I was out of town for a week this summer and came back to a small dino outbreak. I think it was triggerred by the warm weather as I had the ac turned up while we were away. I dimmed down the white leds and got the temperature lower/stable as we had the ac set back to normal. It actually just went away on it's own in about 3 weeks. This just happenned by chance cause I didn't have time to deal with it actively. BUT cyano came in shortly after the dino was gone. I syphoned it out once and it came right back. I've always had high nitrates and phosphates in the past but I hadn't tested for it for a while. I never made much effort to reduce nitrates and phosphates as I never had any issues with the tank.
Decided to test, 0 nitrate and .5 phosphate on api testers. After some reading, I started dosing nitrates to maintain 10ppm. Syphoned the cyano again and only about 10% came back this time. Syphoned the remaining patches and what ever I missed just went away on it's own. There's still a little on my chaeto in my refugium but none in the display.

Sorry, got a little off topic with the cyano. I've noticed nuisance algae really likes white light so maybe it was a combination of cutting the white light and the lower stable temperature that took care of the dino. I don't know for certain. Maybe the chaeto is out competing everything now that there's plenty of nitrates.

Fyi, I don't run a skimmer, don't do scheduled/routine water changes, never clean my refugium and don't run any mechanical filtration.... because I am lazy and stubborn. All I have is chaeto, a little bit of rubble and half a large marine pure block in the refugium.
