I do not use one but can tell you people that do, have troubles keeping Co2 in the water column. Splashing occurs in the sump which is bad for Co2. But others have had success sealing it.
If your concern is keeping equipment out of tank then use a reactor instead of diffuser, inline heater, and very high flow canister filter, and a high flow (mag drives are good brand) water pump externally.
