      Pondvac Question

      About to buy my first pondvac after a dust devil put a huge amount of dirt into my pond that my filters will not move,

      Is here a reason why the manufacturers recommend not returning the water to the pond? Do they do a bad job of filtering the fines?

      Thanks

      Hi:

      You have two options:

      1. the overpriced Oase pondovac, (which works really well for most ponds)
      2. Something that really doesnít work

      Filtering fines at the speed that pond vacuums work is impractical. Youíll either rapidly clog a small filter, or need a massive pump to run a large filter.

      TBH, if you need to vacuum your pond regularly (mine mostly gets used on the water features, although itís also convenient when doing construction or modifications- basically as a sump), you should consider redesigning your pond.

      Hopefully this is a one time clean as the pond went from clear to mud in a matter of minutes. Normally my filters keep everything moving and clear but this time the dirt settled on the benches and the filters are not moving it out.

      Noooo - you don't want to return the water to the pond. The Pondovac does a very poor job of filtering. That's not its job.

      Get the oase pondvac. Itís still working great after 12 years. Never return the water to the pond. That is definitely not itís purpose. If you look inside at least on mine itís just very thin removable sleave around the 2 cylinder vacuum canisters. Those are only to keep the unit itself from getting messed up. Get a 3 or 4Ē pvc pipe and stick it over the end of the vacís discharge tube. That will allow you to empty the water far away. Also sometimes the vac will lose its suction. When this happens pull it out of the water, and let it suck air for 5 or 10 seconds.

      Some obviously have had some long term success with models. Overall with all the negative postings through the years for all brands easy to say they're all problematic if not pampered.
      The real Batman wears polyester! Don't be fooled by the plastic imposter.

      I picked up a used oasis 4 …. Five or so years back and it’s still works great for my 1000g pond. I use it maybe a few times a year to get larger debris out. It’s a very basic “machine” with the only potential thing that could put it out of commissions is the engine dying. Besides that it’s just a few flaps on the inside chambers.
