#reefsquad any help here? My first guess would be to running two current pro's at 80% may be a bit much, have you tried lowering the light to see if anything responds better? Those pro's can be quite powerful.

I’d say first reduce your po4 and dose for nitrate , you have an unbalance .. have you thought about a triton test or api .. see if there’s anything else in your water ..

 

[Reeffer noob]

The lights are each over 1 half of the tank.. the lights are abot 50" long ..the tank is 100"

 

[Jason mack]

How long are your white lights on for ???
Try reducing your whites too max 5.5 hrs

 

[Reeffer noob]

What % should i sent the lights to..

 

[Jason mack]

You should be good with your whites at 30% and your blues 70-80 %

What is the reason for 80° just curious???

 

[Reeffer noob]

White lights are on for about 8 hrs then moolnlight kicks in and they slowly fade to blue... do i need to add t5s or a hailide or are the leds sufficient

 

[Reeffer noob]

80% blue looks good

Have you had the Par tested on your LED's to make sure your settings are doing good or bad.
That would be my first coarse of action.

 

[Reeffer noob]

No.. i didnt want to spend 300 bucks on a par meter.. is there another option.. i looked at the manufactures website but didnt get much info

The seneye is 200. I use that one if that helps any. Or you can post in your local reef forum and see if any users have one that they'd let you borrow.

 

[Reeffer noob]

Is there any other problems that you can see.. ill post pics in a few hours

I have my heater set for 78 and my tank stays at 80.. if i set it any lower (like 76) it drops to 75 or 76

 

[Jason mack]

You could try two smaller heaters instead of one

How are you handling top-off? I had problems keeping SPS until I reduced the SG swing that resulted from my ATO not being in small enough increments.

Do you know what your average Alk swing is?

How are the frags dying? How they die may give a clue as to what is causing it...

My sump has a float switch valve that i top off through with kalkwasser water... i dont have a sg swing because it just replaces evaporation

 

[Reeffer noob]

When the acans died they all looked great for 2 mons then just started melting and in about a week the were gone..
