Blocking Air Manifold Holes?

I just purchased a 35w commercial air pump, and it came with a 6-way manifold to split the air distribution into 6 lines. I only need to currently use 4 of the holes since I only have 4 air stones, so can I block off the other 2 (using a 5" piece of tubing burnt and crimped at the end). Would this be bad as it's forcing air back into the pump or should I just let it blow the air out of those two holes?

Thanks

I could of sworn that I read somewhere that having the air pushed back into the air pump isn't good for it, but maybe I'm trippin'...

Don't melt anything. The air won't be pushed back into the pump, it will redistribute to the open outlets. To close two, just run a short piece of tube from one to the other - blocks them both.

Sounds like a genius solution, thanks

yes If its a manifold it should just reroute the air to the path of least resistance.... i.e. the other holes. My pump has just 2 outlets, but I connected them up with a T-connector, no problems....

i think u read water backing up into pumps is bad.. and it is. but yeah the one hose connecting both is cool. u could also T lines together too probably. aka make 2 lines into one

Get a little one way valve from the petshop, to avoid water running back into your pump, or hang it higher than the target.... hanging aginst a brick wall reduces the noise alot.
