Where do you get the nozzle for $5.00 ?

Gregg, J&L sells all replacement parts for vortechs. You can buy the whole wet side of an mp40 for about 85 bucks, or just components of it.

I've bought MP10 wetsides from them for $58
But you said $5 for the cage ( nozzle )
I was just curious where you get one so cheap

the whole wetside assembly including the cage is about $85

you can buy just the plastic cage by itself for about 5 bucks

muriatic acid works really well, just need to be careful with it

I just run the power heads in very hot water in a bucket with a few cups of vinegar and they clean themselves , i put a lid on it and it will stay hot for almost 2 hours.

Water with bleach 1/2 hour, followed by 1/2 hour water with hydrochloric (muriatic) acid. No scrubbing involved, just run the powerhead in one solution, rinse if you feel like, than run it in the other one. Rinsing after HCl optional.
