fan placement

[big_ben102000]

i juz change my return pump. my water temp shot up reaching 30 degrees in this cold weather !@#$% . i am planning to put a fan to cool down the tank alittle. i was planning to place it in the sump but it is efficient compared to placing it in the main tank ?

go and get a second chiller instead

it shd be e same unless ur light is giving too much heat n heat up the temp of e water in ur main tank....i used to place y fan at e main tank, i shifted to sump cos a bit noisy but found out temp a bit high compared to old location...thus i switch back again..now is better....

on top main tank blowing across would be best evaporation faster, cooling faster... but... top up more often ley ...

correct lo...that's why the first change over was also becos high top up rate..but the heat fm e lights are too great..no choice lo..put back at main tank...

bro chercm no money lar poor student here

both my sump and main tank are 3 by 1.5 by 1.5. i am using NO T5 for the main and 2 ft PL 55watts for the sump.... evaporation doesnt really matter i can top up everyday as long as the evaporation dont cause any salt precipitation, my tank is in my room, dont want my stuff to get all salty. i am planning to get those with 4 fan attached together. but how may degrees would it be able to bring down ?

btw its the return pump that is producing the heat. before i change the temp of my tank was between 26 - 28 during this time of the year

or anyone has any other DIY or cheaper and efficient alternatives to share ? i got this crazy idea of attaching a piece of metal to my iron stand to conduct the heat out of the water ... no idea whether it will work

suggest u dn't get those 4-1 fans..not very lasting.. i'm used before n i dn't really recommend them if u ask...i'musing those singular fan..."sunon" brand.. cost abt $20plus... easier to maintain ths can last longer...
