Filtration and circulation recommendations

Good day.
I have a 2m x 0.8m x 0.7m (+/- 250g) tank that I want to setup with about 30% planted (Driftwood with big sized plant and HC cuba groundcover) on one side of the tank. Planning too add mostly small schooling fish like Tetras, with shrimps, Nerite snails and Otto's to assist with cleaning. I'm also planning on injecting CO2.
As a newby to this sized aquariums, I'm unsure what to do with regards to filtration and circulation.
Can someone please give me some guidance on what would be the optimal way to keep this tank clean and healthy.

Is the tank drilled? A sump is the typical way to go with a tank that large.

No, it's not drilled for sump option.
From what I understand, if you wanna inject CO2, sump filters is a no-no?

I would like to hear more about this, too. I am putting together a tank with a sump, intending to inject CO2 as well. I am hoping that with full siphon overflow, and with just one water fall within the sump, that CO2 will be practical.
Not sure about filtration as I don't have experience at that size but for circulation, I suggest looking at the saltwater pumps. I'm running an AI Nero 3 in my 40 gallon and is perfect for that size. You might have to go for multiple Nero 5 at opposite sides to create a good flow.

Is they are good for SPS corals, they are more than good for planted tanks.

I don't have any experience with it but I have read loads of posts from other forum members who use sumps with minimal CO2 loss. It seems like the general way is to not use baffles or weirs that the water falls over. Eliminate any splashing. You can separate the different chambers with rigid filter material. You can also put some kind of lid on the sump. Inject your CO2 after the sump. Do a forum search for CO2 and sump and you should come up with a lot of great info. I wish my 125 was drilled!

Thanks for this, it does make sense and I'm sure it is possible then to have minimal CO2 loss. Problem is, the tank is not drilled, so I will have to look at alternative options for filtration.
A pair of FX6's would stir up things pretty well.
As mentioned, large canisters are the likely best for an undrilled tank of that size. I would honestly avoid the hassle of CO2 injection if it’s only 30% planted. You can always go that route later if needed.

as to using CO2 with a sump—-it’s possible. I’ve even used one with a trickle filter, you just go through much more CO2, but gas is cheap and it wasn’t difficult to keep the levels up.
