    Ventilation under decking

    Like most people my filter is under decking. With all the constant rain we get in Manchester and me painting my decking with a treatment that is fish safe I got from Canada bits of mould and the beginning of wet rot is appearing in places.
    is like to put a fan to circulate the air more in there. Does anyone make small air powered ones as I could run it off the air pump or anyone else have any ideas.
    Thanks

    Jim

    Is there any air gaps in your decking? If not them maybe try a couple of fan grills to let some movement of air under there and it wouldn't cost anything to run just a few quid for the 2 vents.

    The paint you applied may not allow the timber breath properly and the moisture is getting trapped inside the timber/under the layer of paint.

    good suggestion but its not that as I only painted the side facing the sky and the treatment I got from canada lets the wood breathe as it is not a sealant.

    the timbers are wet on the frame work of the decking underneath and the supporting structures.

    need more ventilation in there.

    sounds cheaper in the long run to replace with composite
