Cyano issue

Seems I am having an issue with cyanobacteria.

I have no idea what is causing it.

All parameters are prefect and within the levels they should be at.

Phosphate, ammonia, nitrate is zero,
magnesium is 1250ppm,
calcium 420ppm
pH 8.2
Temp stable at 80F raising to 84F when the full lights are on.
SG 1.025

Lighting is a T5HO 72w Quad unit (soon to be this unit)

Feeding is twice a day and with only two clownfish is minimal.

Thoughts and suggestions?

How old are the bulbs again? Replace after 9 months.
Feeding to much. Go to once a day.
How long are your lights on for in a day?
Temp is a bit on the high side. I'd not let it come above 80. I know your within norms, but its really a bit high.

Bulbs are not even 6 months old.

Ok, will drop feeding to once a day.

Lights are Actinics on 11.30am-9.45pm, Daylights 12pm-9.20pm, Blue LED moonlight - dont really use them.

Will drop temperature to set thermometer at 76F should keep the tank just above 78F when all lights on.

to much food and dont forget to pre-rinse frozen foods before feeding.
do you use GFO in a reactor?

if you can add a small clip on fan ( or ziptie it ) to your canopy to come on ( @ say 80 degrees if you have a controller ) to blow across the surface of the water. this will increase evaporation but can help with high temps.

I agree with all said above.

An easy way to immediately remove cyno is to suck it up with your mixing pump. I attached a small hose to the intake and a ball valve for control. Worked like a charm.

But this wont solve the issue, whatever is causing it must be fixed or it will return.

I made a cooling fan out of a phone charger and computer fan, then mounter in under my 3rd chamber cover (or could be a hood depending on tank) with 3M car tap.

It lowered my temps from 84F to 80F. A cheap alternative to buying a chiller if temperature becomes a constant problem.

this is important because yes, it will return and/or other algaes arise from excess nutrients.
i have also used a product called chemiclean i believe ( follow direcetions to the T ) and had good results but again this is AFTER adressing the issue.
small water changes of siphoning it out, cut back feedings, increase flow, GFO reactor, are all good places to start and see where that leaves you. i would use the chemiclean as last resort.

for the fan im talking about literally getting a small plastic house fan and using that. computer fans do work and ive used them in the past but ive found they like to short out more so then small house fans.

At the back of this tank (mine) you can see the lil black outline of cpu cooling fans. Lil black square fans, mounted to the back. I have 4 of these on mine, and am using 2 250w halides. Keeps my tank at 80 in the Summer, in Arizona.

Thanks guys for the suggestions, I have already cut the thermometer down to 72F as of my last post this morning and will full lights it is now 78F.

I did find a dead crab in the tank shortly after I posted, removed it and some of the cyano. I have water mixed ready to go for a change tomorrow so will get a lot of the cyano out when I do that.

It could be my bulbs in my lamp, so will monitor them until I get the MH unit I posted earlier. I suspect though that I have been overfeeding so have cut that down to only one feed a day and will start off very small and increase as needed.

Yes. Feeding once a day in my opinion is more than enough. I personally feed frozen food every other day with pellet food fed in between because it pollutes the tank. I also skip a feeding once a week to keep excess nutrients under control.
