Spare HOB

Hi Guys! Is it okay to use an HOB filter in a heavily high tech planted tank?
I have a spare emperor 400 lying around i wanna use it(not the bio wheel) to add additional mechanical filtration,i will just raise the water level so that it will create to much water agitation(out gassing).

Set Up:
75gal heavily planted with pressurized C02
Filtration: Fluval 405 / Sun sun canister filter(smallest)(Just bought it last week already in transit)

IMO, there's no such thing as too much filtration, unless your fish can't handle the current and you're blasting plants right up out of the substrate. I'd say go for it.

10 gallon acrylic fw planted. 6 neon tetras, 1 GBR, 3 Amano shrimp, 2 nerites, 1 BNP, Eheim Classic 2211, Finnex Planted+ 17W LED, Hydor ETH 200W In-Line Heater, InkBird temp controller.

10 gallon aquaponic setup, hydroponic basil, 8 HET rasboras, RCS, red ramshorn snails.

I would certainly go with more filtering if that is wanted to get the water clean looking. The possible downsides are that you may find a little too much flow so that plants are blown down or something that you don't like but that would be secondary concern for me. There MIGHT be a small increase in lost CO2 but that wouldbe my number three concern.
I want clean, good looking water first, good looking plants second andmthen worry about losing a little more CO2.
Reasons? I can do something if the flow is wrong and I can afford more CO2 but I can't stand bad looking water.

I used the emperor 400's and 280's for long time in planted tank before going to canister's.
Just be sure like you said ,to keep water level high enough to eliminate waterfall effect from the return= less CO2 off gassing.
