Question A couple of Questions

For a 4ft x 2ft x 2ft tank what reccomendation for filtration should i use?
Iv always used cannister filters in the past and am looking for something suitable, altho i am open for other suggestions other than a sump.

The tank will have a sand substrate and will be planted.

Also the age long battle between having CO2 and not having it installed, opinions on this please.
Iv not had it before and am onsidering it, the new set up will be a balance of what i do know and new things i havent done before.

Thankyou in advance

Fish will brighten your day even when the world tries to darken it

The intend fish stocking (thinking here of the types of fish) is important when considering filtration. But as you intend a planted tank, I will make the assumption that you are looking at smallish community fish and not a tank of large cichlids or similar. So the best filtration is a good canister rated to the tank size.

As for CO2, that is up to you and will be determined by what you expect from your plants. If you just want live plants to beautify the tank and help create a natural biosystem, you don't need CO2 diffusion. If you want to fast grow lush plants with flowers, you probably will want CO2 and higher light to balance.

Check the photos under "Aquariums" tab below my name on the left for some examples of planted tanks with no CO2.

I echo the sentiments that a well rated Canister is a good idea for a tank like this. However, remember that what a canister is rated as on the box doesn't always translate into it's full power once it's full of media.

A common tactic to ensure even filtration and a proper current in larger tanks like this is to pair a well rated Canister with something else. It could be another Canister. It could be a power head. It could be something as simple as a sponge filter. Anything to help complete the current and ensure you eliminate low oxygen spots or layering. If it were me and I had the money to burn I'd sink money into two canisters. Instead of getting one big one that matches the tank, divide the load up into two smaller canisters that together match the tank's specs. Then you can customize your media and have a really nice filtration system set up. It also means on the off chance you ever experience failure with one, you have another to act as a back up till you can fix the failed one, or get a replacement.

For this size tank, and ease of service,customization, I would select Rena XP4 which I believe API now distributes.
Is dependable filter, and would still provide good circulation,filtration,even after basket's are full of whatever media is chosen.
Priming the XP filter is much easier than priming the eheim classic's which I also run,and they aren't as expensive as many other filter's with same GPH rating.

The most important medication in your fish medicine cabinet is.. Clean water.
