Hi. ive read multiple articles that say u should have overfilterd tanks when using co2 for better distribution of co2. So i put an Auqa 3 into my 20G long (allready using an Aqua 2) and basicly it looks like a tidal wave :? The plants look as tho they are struggling to stay in the substrate!! (fish are loving it tho) So how am i supposed to 'over filter' without ripping the plants up with the current? Im not yet usning co2 as all the parts are in the post.
