The question you should be asking is why do you need a trickle filter? Reef tanks use it for biological filtration. A planted tank should have enough surface area within the tank for bacteria that you don't need supplemental biological filtration. Most people leave out the trickle part and just have a sump. If you go ahead with a trickle filter then you'll need to make sure it is fairly well sealed. Otherwise the CO2 will likely off-gas into the air. I ran a trickle filter on my 150 for a time and went through CO2 quickly. I switched to just a sump and now go several months on a CO2 tank.
