Cooling Fan in Main or Sump Tank???

[bkburger]

Which is best? Blow at main tank or blow at sump tank? Anyone can help? Thank you

[stevenkoh08]

sump tank if space allowed

meanwhile you also lower the heat of ur sump compartment

but first ur cabinet must have ventilation

[peacemaker]

Depending on which tank has a bigger surface area, blowing across that will have more cooling through evaporation. Having it at the display can also help take away some heat coming off the light set.

I would prefer to blow across main tank, as this will take away heat from the lighting. Sump tank is good if there is ventilation, else not very effective if sump is in an enclosed cabinet.

you can also consider a fan on both tank and sump. just take care of the evaporation.

[mecedesfish]

yes, be carefull with the sump and top up level. The rate of evaporation is very much.

Main tank!

Though cabinet have vent but still it's not as free as main tank.

Most effective I find...

...but if your cabinet is enclosed, having the fan inside would probably be quieter.

You can have a strong air pump to bubble air in the sump, this way can also get rid of the "heat" as it helps evaporation of water, but the salt remain behind so you have to top water.

Lol... When air also cannot get out of coz quiet la...

But no use la. Waste effort waste electric bill...

Y u say that?

By purchasing a chiller already more ex than a fan le.

Then every month bill for chiller compare to a fan definitely gonna be alot more ex.

Need a pump for chiller as well.

Catch no balls pls enlighten.

Only thing for fan is they can never achieve the kind of temp the chiller can achieve n evaporation takes place faster than a chiller.

Need top up water very frequent.

unless you stay in Middle East where H2O is more expensive than electricity.
