MH lights heating my tank.

If it's not one thing, then it's another...

I came home this evening and my tanks temp was pushing 86.4. Ouch.

I turned off one MH, turned on the AC, and have a fan on the tank. It's
starting to cool off, but what now? Chiller? Any other tricks?

Kurt,
Try one of the 6" clip on fans blowing over a sump if you have one. I use
2-250 watt MH and 2 VHO actinics on my 65 and 90 and with 2 fans in canopy
and one blowing over my sump and I never have a heat problem. I do have a
1/10hp chiller just in case though. Tanks stay at 78-80 max even in the
summer. On our 29 frag tank we do have a heat issue with 1 MH but a bigger
fan helped.
Water surface cooling does wonders for dropping tank temp but also
accelerates evaporation

Yep, fans do a great job of cooling the water. I prefer to
put it over the tank instead of the sump for 2 reasons.
(1) more surface area to evaporate
(2) fan in sump can tend to get salt spray into the air.

I added a fan that blows across the surface and light fixture. It's
staying cooler, but evaporation is higher too. I doubt that's a long
term solution given my locale, but it will hold me until next month.

Thats one of the most common in use methods of keeping a tank cool
though. Short of a chiller, fans are the fine. They do become
marginal at best once this region (where you and I both live) starts
to get a bit warmer........I find I can not keep my tanks cool enough
in spring with just fans if the ambiet temp gets much arounfd the 80;s
so it gives us a good excuse to turn on the AC.

I forgot more about ponds and koi than I'll ever know!

I knew someone who put a 2 litter bottle with water in the fridge and then
put it in the sump when it really got warm.

It seemed to help.

While that may help it does not do any good if your not there to put
that frozen bottle of water it in the tank....
Best bet is to address the problem and correct it. Use a fan if yu can
not afford a chiller. They are easy to mount under a typical hood etc.
and if yuu power it with an adjustable power pack (wall Wart) you can
speed the fan up or down and vary airflow to suit temp conditions. I
normaly run my fans on 6VDC most of the year. In early spring before
the AC is turned on, and its getting warm outside and inside I turn
the voltage up to 9.6 or 12 volts and give it more powewr and provides
more cooling flow so tanks run cooler eventhough its getting hot
outside. Same for when we have to fire up the heat, I speed up the
fans to push more air flow over the tanks surface water for more
evaporaiton and more cooling. The drawback is increased evporation so
more or larger top offs are required, but its stil better than having
a hot tank to deal with. Iyts also a failry good idea to keep a heater
pushed up and working against the fan so they more or less work
against each other. Thhis usually accomplishes a fairly constant temp
range the tank runs in., and with a bit of experimenting, you can
figure the ideal tank temp to run...

I've dumped ice in my 125 with no noticeable effect. Good luck with that.
