    Had a customer ask if i would drain and clean out his pond (4x6x3deep). Any idea what to charge, and is this going to be a pita!

    We normally charge for that small of a pond a minimum of around $200. That includes:
    1)draining the pond with a sump pump, 2)removing the goldfish or koi, 3)using a pressure washer with about 2500 PSI to removing any string algae on the rocks. While power washing the sump pump will remove the dirty water and algae. 4)After all power washing is done you should spend a good amount of time rinsing the rocks and shelves if there is any. Finally, when the pond is about full add some dechlorinator and transport the fish back to their beautiful pond.
    Hope that helps:)

    Wouldent you want to add the fish only after getting them slowly used to the new temp of the water you just refilled the pond with 1st?

    It will be a pain in the arse when you kill that customer's fish, because you exposed them to a 100% water change. This 100% water change will probably shock the fish because of being put back into a pond that's more than likely drastically different in temperature, than it was when they were removed. The water that you're putting the fish back into also has a totally different chemical analysis than the "dirty" water you took them out of (another sure way to shock the fish). If that's not enough.... Let's say that the fish do survive the shock of this 100% water change. All of the nitrifying bacteria that was lining the walls and floor of their pond has been removed. So... When Spring rolls around and the water temps raise enough to facilitate feeding the fish and waste is consequently introduced into the pond again, your biological filtration will be non-existant (unless you manage not to kill the nitrifying bacteria in your filter, which you probably will). Nitrites, nitrites and ammonia levels will quickly spike to dangerous levels and voila. More than likely dead fish. If the customer catches this spike in time, they can always do massive water changes, but they're still going to have to deal with nasty algae blooms (if they don't have a properly sized and set up U/V).

    If the pond needs to be cleaned Ace, do it as part of a partial water change. I'd never recommend doing a 100% water change on a pond, unless there was some sort of emergency that required doing so. The biggest water change you should ever do unless forced to do otherwise, is a 50% change. Under normal circumstances, a 30% water change is about the most you'll want to do.
