lowering temperature

[mikehooi]

hi guys out there,
like to thanx u all for advising me in my canister problem.
now another issue of my tank:temperature.

currently my tank is very warm.
the 12 gal tank is 32C
the 22 gal tank is 34C

is that bad for plant?i experienced a lot of melting plant.except riccia and amozon sword.other than that everything seems not doing fine. is there anything i can do?

wat i plan is to install DIY fan.but how much can it lower the temp?
1 fan for the 12 gal :
and 2 fan for the 22 gal.

btw it shall blow on the water surface or at the casing(ballast)?

hooi,

I think 1 each will be sufficient. estimate around temp drop of 5-6degree, fan shld be directed at the surface

The fans ought to be the standard size too. ( I wonder what's the mm size )

For me, I tilt my fans at a 45 degree angle. I see people doing that too, so I just followed suit.

Anyway, just as a reference: My 16 gallon is doing 26 degrees approx with 2 fans at 45 degrees.

Try lowering the temperature, and see if your plants survive.
