After having a problem with water getting into my co2 diffuser causing a really irritating drip drip drip sound every time co2 passed through it,I installed a check valve hoping to prevent any water getting back

to the solenoid.but since then the co2 bubbles have been collecting on the surface of the water (see pic).is this a problem apart from not looking very nice? Also, has anyone any ideas how to stop it?

Water will alway get into the Co2 diffuser when the Co2 is not in use, the gas (C02) pressure will force the water out of the diffuser and enter back into it when the gas pressure has depleated, you have done the correct thing add a check valve as you dont want water in the solenoid. As for the bubbles this will always happen when adding co2 using this your method, the way to remove this is to have a slight surface ripple which will dispurse the gas bubbles. there are two way of mixing the gas within the water column so no bubbles within the aquarium
1. use a reactor with bio balls or filter media
2. or as I do place the diffuser under the filter intake pipe and mashes the bubbles up whilst passing through my filter media.

Thanks, my reactor is placed under my filter outlet the way you said but I've just never had a build up of surface bubbles before.usually powerhead pushes co2 round tank and it dosnt rise to the surface like that.

Potentially exaggerated if the water surface has a film or theres not much surface movement to let it break through
