Hi all. My tank jumped up to 30C Scorcher of a day.I have setup a single fan (one of those cabinet extractor fans) blowing directly onto my DSB. Is that ok.How quick should I see a drop in temp?Anything else i need to do?

Buy a chiller.

Fans work as you have set it up, but if you having problems now, in a couple of months your water is going be boiling.

Loads of fans where ever there is water surface.

i am being serious, today was cool compared to where it will be in December and if you having a problem now it is going to be hard to keep your water temp constant when the air temp. is 35 - midday and then 15 at night.

Other option is run a hotter tank and pray.

Damn Goodisor, looking at your location i would definatly look at a second hand chiller of some sort or an airco unit.

My tank is starting to do too well to let the temp kill it.

This decision you wont regret.

Next buy on my list, and watch out for evaporation rates with the fans - I don't think you'll have a big problem 'cause of your humidity down there. Up here on the ref it goes through the roof.

Install fans temporarilly but save up for a chiller. Increase the heater temperature to 27 degrees. That way it remains constant. Sudden increase and drop of temperature will stress out fish and corals.
Thanks Mekaeel. I installed a fan today and i just went to set my therm to 27C. Im going to get a chiller from SIMS as soon as finances allow.

Haven't had a days problem in JHB. Temp never fluctuates more than ).6 degrees and that is with fans only.

The less humidity the better

Hey Warr,im in the heart of Zululand.In the middle of summer the ambient temp can go to 40 C with a discomfort factor of 8 or so.Humidity can can go to 80%+...but even still,the worst my tank temp ever went to was 35C and that was my previous tank which was indoors with a lid and all the lights and ballast were closed in. Now my tank is set in the wall with everything in my garage and the highest its been is 32C right through last summer....still too high but ive never had a fish die from it yet.The fans will work for now but ultimately im going to have to get the chiller

DOn't worry, i ran my tank at 35c for 6 weeks without any fish dying.

Only prob was the coralline went insane and also had loads of algae issues.

Apparently if you keep the temperature constant, not up and down, you can run almost any temp

Thats encouraging.Thanks for the tip. Fortunately i have a FMWLR,so corals arent a big issue.And if i buy any i will be sure they are the upper temp limit type

there are pro's and con's at running higher temps. Not sure what, I think some guys have used for speeding up parasite life cycles or something

I was only warning that you may need to top-up alot more often. I don't have the luxury of a big reservoir so I need to refill it way more often in summer.:wave2:

I agree that the fans keep the temp down brilliantly.

I read somewhere that evaporation is good for dosing kalk and keeping the pH stable

This is not sound advice at all and these temps should be avoided, esp in systems with inverts or fairly large fish loads. Oxygen in water is very low at these temps.
