pump for co2 reactor (small)
hi
i recently added a small co2 reactor (inline pvc tube type, co2 provided by 2 * DIY yeast tanks producing 1 BPS co2 each) to my small 35 litre planted tank.
I added a boyu c1000 internal pump to force water into the reactor which works well, however the pump heats the tank by 3 degrees (i.e. instead of 25-26c, i am now 29-30c). After about 3 days, my moss is looking a darker color now...
my filtration is powered by eden 501, and i read some AQ posts explaining that adding an inline co2 reactor to the 501 may not be a good idea as although it is rated at 300gph, it may slow down between cleans due to clogged media.
I checked some shops and external filters are quite big and expensive (many are of comparable price to the eden 501).
what is a good solution for my predicament?
in order to keep the temperature down, should i go with:
- an external pump (25-50 SGD)
- another eden 501 (similar price to above) without filter media (also acts as a backup filter)
- another alternative i had not thought of yet...?
cheers,
