So I’m dealing with Cyano and have been trying to get a hold and stabilize my nitrates and phosphates. In trying to make sense of what I’m dealing with I have decided to test nitrates and phosphates daily at the same time daily to get an idea what areas I may need to deal with. That being said my nutrients seem to vary considerably daily. Perhaps this normal but with the amount of water in the system (450 gallons) I’m thinking something else is at bay.
I test alkalinity, nitrates and phosphate every morning before lights come on and any feeding for the day. One day I may have 4-5 nitrates and .07 phosphate and the very next day 25 nitrates and .13 phosphate. The following morning nitrates will drop back to 3-5 and phosphates.05-.07.
I have been trying to get nitrates up by dosing ESV’s Nitrate but at 1/2 recommended dose to raise nitrates 1ppm so I feel I’m way under the amount to have it jump 15-20 points.
I feed 1x a day with rinsed frozen mysis and 1 sheet of nori for tangs every other day
Tank is roughly 3 years old. I am in the process of removing the sand bed slowly which I know can release nutrients but I do a 50 gallon water change once a week and remove some sand. I can’t believe this would make nutrient levels go up one day and down the next. Any ideas ? I’m wide open for suggestions!
