too hot

how close are lights to water??
im already running my ac to keep my tank cool!!
if you dont have ac ,or dont want to run it all day
if it gets to hot have the lights come on at night instead????

"what do i do help thanks for any info"

Get AC If it's heating up that much now think about when it really gets hot.

Are the MH lights mounted inside the canopy? May be try hanging the MH lights and ditch the canopy ?

they are in the canopy i was wondering what temp the tak should be at high and at low points like in the morning when the light first turn on mines at 79 in morning and 83 at night sometimes it at 84

Here's good reference table (from Randy again) on recommended water parameters. Temperature is oneof the ranges discussed:

so 76 to 83 is ok then i was thinking the closer i can get the temp to hi and low was closer than that i guess mines ok at 78 and 83
