Filter Pump

[Locke]

Hello all, I have a saltwater aquarium and it's been running for quite awhile now. Today I just noticed that my filter pump isn't pushing very hard. I opened it up and looked inside, the water was a little low. So, I added more water to it and turned it back on. It's still not working. Lol. What do you all think that the best course of action is?

20gal. tank
seaclone protein skimmer
H.O.T. Magnum canister filter

I think what I'm going to do if I don't get any reply's is:

1. Turn off filter
2. take biowheel out and float it in tank
3. take filter and pour water out.
4. Wash out with tap water, make sure there is nothing blocking the pump.
5. Wash out intake and exhaust valves and make there is nothing in those.
6. put back together and run again.

If it's still broken, I'll either buy a new one or try to get my lfs to take a look at it.

Thanks in advanced ya'll

Well, I did what I said I was thinking about doing in my last post. Yes, it did increase flow in the tank, but it's still at about 75% of it's original strength. Hopefully it doesn't go down any more until I can fix it all the way or buy a new one.
