A little murky now, but once you fire up the filters, it will clear up in no time. I find if I can rinse the rocks/gravel/boulders a couple of times, then use an old pump to pump ot the dirty water from the pond, it helps with the initial flow of dirty water coming out of the bogs and filters.
Keep an eye on the pads. Let them get a little dirty before you rinse them. They work better at trapping particlates when a little clogged. obvisously don't go to long w/o a rinse, or back flush in your case. Can't wait to see the air in action.
Well done sir.....
