i have a 120g (4x2x2) and i would like to have it be a planted tank. would it be better or make a difference to go with a HOB filter (2x penguin 350's) or a canister filter (1x eheim 2026)?
Morphineh;4487065; said:Bob, I would strongly suggest a canister filter - Eheim is def the way to go.
If you want to do a high tech planted tank you want to limit surface agitation this is gas out your CO2. Assuming that your using Co2 in your Planted tank.
Also with a Ehiem depending what model, you can also line in your co2 and it will diffuse your co2 and also add an inline heating system. This in my opinion makes your tank better looking by cutting down the amount of tech seen in the tank. It also opens up spaces to add plants.
Hope this helps!
