Cooling A Tank Down?

[lilfishie]

Is there anything else i can do to cool my tank down? the lid is open, bottle of ice in there and a fan and its still not cooling its up on 29C when its normally at 25 max, luckily its only 1 of my 8 tanks thats too warm currently but its the tank with know jumpers in

more bottles of ice???

how about a 50% water cahnge - your tap water should be much cooler.

 

[lilfishie]

theres already 3 bottles in this tank its only a 30 gal i have done a water change which has brought it down a little but not sure how long it will stay down its roasting here! we got all the windows/doors open too

 

[ZoddyZod]

blimey! Anyway to increase the circulation of the water and thus have an increased flow around the ice bottles?

I have seen people using open ended airlines before, they said it worked well.


eg. no airstone

Mine is warm, luckily its cycling, I think it's just the weather.

 

[lilfishie]

the tank has 2 fluval 3+ running on full 1 at either end

will give it another hour or so and if still not any better will have to do a big water change the lights are off, both bits of lid open (its a Roma 125)

Have stuck a thermometer in and turned the heater off (its a fluval e with digi display) hopefully i can get it back down before someone desides to jump

how big is the fan?

this used to keep my tank cool in the middle of summer without opening the hood

Mine is the same tank, I thought it was the lights first because I've just set it up and my plants are all living and need the light so I've cut this down to about 2 hours a day. The temperature is 27 and the heater is set at 24. But the temperature of my room and outside is 29 - 32 so I think thats why mine is warm, the lights don't even get that warm after they've been on.

I tried a fan but no temperature changes either

If it's bettas you have in there, then 29C should be fine for them. They prefer temps nearer 30C, apparently.

Also, you shouldn't need to turn off your heater as it should only switch itself on when the water temp drops below the setting you have it on.

In the summer, my aquariums often reach 28/29C with no ill effect on the fish. I know it does depend on what fish you have as some may be a bit more sensitive about heat than others. Certainly you wouldn't want the temp going much over 30C as that would more than likely stress them out (as well as stressing you, too).

I think you're doing all the things possible to help control this situation. There's not much else you can do unless you can get an air con unit.

I should think that even with a fan on it will just be throwing out warm air.

If you continue doing regular water changes (small ones a few times a day) that should help.

my light unit does get quite warm but only normally changes the temp by 1C at most and thats when they've been on for a full day.

i only have a desk fan its sat on my 2ft tank blowing the top of the roma, the tank itself feels cold to touch but as said its very warm here today.

i also have plants in the tank which is not good having the light off, i'm hoping theres just enough natural light to keep them going.

its moved to 28C now so hoping that its going to keep coming down

Athena thanks for the advice there is a betta in there my main worry really is my plecos (L052 & 2BNs) and my SAEs attempting to jump i am not leaving the room with the lid off so should here if anyone makes a leap

i don't think the heater has been on but i unplugged it just incase, i've had my share of bad heaters



I have also noticed that today the tank is quite cloudy, all stats are perfect, all fish acounted for so no bodies, all food eaten within 40sec excluding veg which i haven't added for a few days anyway. Anyone have any ideas?

Try not to get too stressed by this, Lilfishie. Most tropical fish can withstand varying temps - in their natural habitat temps are not at a stable set amount, they fluctuate from day to day and some days are invariably hotter than others. But increases in temps like that are usually gradual, over the course of a day or so rather than sudden hot to cold. I'm pretty sure it will have been the same in your tank - a gradual increase.

As said before, bettas prefer warmer temps. The plecs should be fine, too, as they are quite happy with a temp up to 27C (but, again, they can tolerate varying temps so a few degrees higher should not harm them).

Sorry, having a bit of a dumb moment - what's an SAE (apart from stamped addressed envelope LOL)?

Cloudy water could be the sign of a bacterial bloom. Now this might be due to your filter bacteria going through all these temp changes, especially if the ice packs have chilled the water around the filter too much causing some of the good bacteria to die off. I'm no expert on filter bacteria, though, so maybe someone else might confirm that assumption.

It will usually clear up once your filter bacteria has re-established itself and back on the proper level.

It can also be caused through over-feeding (happened to one of my tanks when I left my mother in charge of feeding my fish!) But as you said they are eating all the food you're giving them, then this surely can't be the cause.

Hope it all returns back to normal soon.

Siamese Aglae Eaters. i have 2 of them, never had them attempt to jump before but my partners jumped a few days back and died so now i am extra careful with them

at 1st i thought the cloudiness was due to a new food i am using but the other 7 tanks haven't clouded and they've had it too.

hopefully its not done to ,much to the bacteria then

Pointing a fan at an aquarium in an attempt to cool it will have no effect. The air that you are blowing around is still the same temperature. inanimate objects do not experience wind-chill factor.
