Tank cooling, fans, ice...

[Koh23]

So, temps are dangerously high, up to 40C, room temp is maybe little lower.

I have one big fan, room type, blowing into water in dt, have one 120mm fan blowing in sump water.....

And it hardly can keep 27C... Of course, air temp is 34-35C, so this is great.

But i need advice, what else can i do, maybe another big fan on oposite end of dt, ice bottles, cubes.....?

I had a heater break on me and overheat my tank to 85f. I put a bunch of ice in zip lock bags and floated them with a fan blowing across the top and it cooled relatively quickly.

I just did the conversion and that's 104f. Is anything still alive? Is your ac broken or is this a normal temperature for you?
If you normally have room temps higher then 80 you should look at getting a chiller.

27C (80.6 F) isn't dangerous yet.

Rotating frozen plastic water bottles in the sump works pretty well. Increasing evaporation with fans usually works for a couple degrees F, but with air temps that high, it may not be good enough.

Yes, everyrhing is alive and doing great.

27C is not too alarming, but it creeps up slowly, it was 25, then 3 days later 26, now its 27.....

Total water volume is around 500l, so, any suggestions how much bottles will it take? Kinda doubt that one coke bottle will have any impact on that volume?

Sadly, no ac....

I have 6, 5lbs cooler blocks that I rotate 2 at a time with my 75, about 100 gallons total volume. I usually do this once temps reach around 84f.

So, lets say, 3 cola bottles, 2l each, at same time in sump should have impact, at least 1C down?

I don't know how things are in Croatia, but I have a window air conditioner that keeps the fish room cool. They are readily available and relatively inexpensive (5000 btu does it for me)

I know....

That was a plan, but sadly..... Sometimes, plans changed.....
