I just got done getting rid of a cyano outbreak, I dont want this cyano to return. I believe the cause is the LEDs I got, thats when it started. I have started keeping my lights on alot less than before and nothing has popped back up. I am not sure if I have a phosphate problem or not. I dont have a phosphate test, do I really need one? Is the Hanna test worth it? Is it accurate? Or would I be ok buying the API reefmaster test kit that comes with 3 or 4 other tests? And after I get that, should I get some sort of phosphate reactor? Are they necessary to run all the time?
