t5 bulb possibly causing cyano problem

[ironworker]

i have had a bit of an issue with cyano lately and im thinking it may be my bulbs. 4 bulbs 2 actinic plus 2 aquablue plus all giesseman.
2 are 9 months old and 2 are 4 months old only problem is i have one aqua blue and one actinic that is 5 months old and the same with the 9 month bulbs. and i cant tell which are which.is 9 months the life span or is my problem somewhere else maybe.

I was getting cyano on 8-9 month old geissmans. I just switched to ATI. And sucked cyano. All clear now

How long do you have the lights on? Cutting time they're on will or should help.

highly doubt it.... cyano is from lack of flow and a over abundance of nutrients.... whats your flow look like?

More then likely it's a mix of problems. Like stated above what is your flow like and where are you phosphates? I would replace any bulb after 9 months. If it were me I would also change all the bulbs at the same time to avoid any confusion

flow should be fine i can kick the sand up if i want. im unsure of phosphates i dont have a ckecker but i tumble gfo and change it regularly. i think i will start changing out bulbs this week.

I would change just the two old ones first. Then in a couple months the other two. Not all at the same time. So coral can adjust to the new lights.

I use a sharpie to write the month/year on my T5's when I buy them so I know which ones need to be changed out.
