Are your plants all plastic? It looks like it. If they are, the plants will probably be rigid enough that the intake won't pull them in as long as they are at least an inch or two away, and the flow shouldn't be inhibited too much if at all. If they are live, however, you risk that growth and lack of rigidity will probably lead to them being pulled into the filter intake at some time, so intake placement plays a much greater factor. It doesn't take long for live plants that are too close to an intake to plug the intake strainer, get sucked into the impeller, clog the filter media, etc. due to growth and flexibility. Once any of these things occur, your filter efficiency will be drastically reduced.Ya know, on tanks 20g & up I like 2 filters. They create better flow & suck up more detritus. & I can clean 1 filter every few weeks, then the other inbetween times. For your corner tank I'd go with 1 on each flat back, in the middle. But for now Dee has it right...
& we're still going to discuss live plants soon-ish...take it as a threat or a promise
That changes things a bit. I can't make out anything about your filterfrom the pic and assumed you had an HOB filter. I suggest putting the intake on one of the flat sides of the tank and the discharge on the other flat side, both of them in the middle. That should keep water circulation decent and as long as you have a good flow rate should be adequate.Yes plants are all plastic. Right now I have the canister intake in the back corner part and then 2 small sponge filters on each side.
Its a cascade 1000 canister. Yes I have 3 pearls, 5 harlequins, 6 white clouds, 6 sterbai corys, clown pleco and 2 nerites. Thinking about adding a bristlenose to help clean the sides of the tankThat changes things a bit. I can't make out anything about your filterfrom the pic and assumed you had an HOB filter.

It looks like you have a couple of pearl gouramis, with schools of harlequin rasboras, white clouds , maybe some kind of corydoras , a large snail (mystery snail?), and a lone pleco. Other than the pleco, none of these fish produce an extraneous amount of waste, so keeping the water well circulated through the tank will be as important as where you place the intake and discharge.

Bumb h rasboras to 6. Bushy nose plec is fine.Its a cascade 1000 canister. Yes I have 3 pearls, 5 harlequins, 6 white clouds, 6 sterbai corys, clown pleco and 2 nerites. Thinking about adding a bristlenose to help clean the sides of the tank
