That's pretty well my set up. The only truly gross part is the Fall clean out of the filters. I pressure wash the filter matts, then use the ShopVac to suck out all the muck and crap from the bottom of the 55gal plastic barrels, dump that throughout the garden, set the filter pads back up in the barrels, then put the lids on for the winter. Come Spring, I only have to turn on the pumps.......Voila, I'm up and running.
I've used D-Solv powder in the Spring for years, where you just sprinkle it all over the surface of the pond, in a few minutes all the leaves and crap miraculously floats to the top where I can scoop it all out with the pool skimmer, then suck up the rest with the PondoVac 4. Here's what the packaging looks like (see link).

Of course, this year Spring has been cancelled (at least for us poor, winter bedraggled Ontarians). I was ice fishing on Lake Simcoe yesterday, two miles out there was still more than 18" of ice.
D-Solv sounds too good to be true. It actually makes debris etc. float to the top or is it just solid leaves? Do you still have annaul pond bottom cleanings to femove muck? I do not have fish so the stuff on my pond bottom is from leaves.
Please reply with the pros and cons.
