i tried jello co2 and while it does last a while, but you have to take into consideration that after 2 weeks you will have to recharge half of the mix.. so as i found out while it did give me good co2 output, its a PIA to maintain it with jello co2.. Just go with the standard mix and recharge it every 3-4 weeks..

Also everyone is saying that hob filters and co2 is a bad idea.. Well not sure exactly what the problem is, I am running hob on both of my tanks and there is sufficient amount of co2 in the water for the plants to indulge on..

Sorry, yeah, you can use co2 with an HOB, but if you can choose, choose a cannister.

For the original poster, you won't need two filters on the 20, so use only the fluval cannister.

I wasn't planning on putting two filters because I know that is total overkill for a 10 or 20 gallon tank... I was just naming the two that I already have to see if they were usable for a planted tank or would I need to get something else.

Again based on what I've read... they say HOB filters aren't good because the agitation of the water dissolves the co2 or something like that. I could be totally wrong.

If I opt NOT to use my cannister filter (want to keep it with my 55 gallon tank), would a basic HOB or very cheap cannister filter work? What is a low price but decent quality cannister filter? All I know if Fluval and they aren't cheap.

With a 10 gallon tank... is co2 really necessary, or would the fish produce enough for the plants?

Yeah, you could definitely use a cheaper cannister filter. Again, you can use an HOB, but you'll have to add an extra amount of co2 in order to account for that which is lost due to the HOB.
