I have a Oase Pondovac 2 pond vacuum that I bought in 2005. It still works really well for what I need it for. I don't know if a shop vac has more suction or not.

Thanks Cas, I hate to say it but my fish are pretty.... dumb. Maybe sheltered is a better word, so I'm not sure if I should be worried or not about vacuuming them up.

I have a shark steam mop and I love it. It cleans really well and no chemicals needed (which is great since I have asthma and the chemical smells can really bother me at times)

I got a pond vac for christmas but haven't been able to use it just yet due to winter weather (very soon though) I have used a shop vac to clean the bottom of my pond a few times (pond is three feet deep and the vac sucked up the gunk very well) the main problem was that I had to dump the vac as it filled with water and gunk and that wasn't fun. Every time I used the shop vac I drained the pond as far down as I could and then used the shop vac to clean the bottom of the pond (put fish in a holding tank) keep in mind that my pond is fairly small and only about 500 gallons. Oh also, I removed the filter from inside the shop vac before sucking up any water (first time I used it I forgot and ruined it)

Oh, forgot to add that I would and do worry about fish getting sucked up in the vacuum. I haven't had it happen with the pond fish but it has happened with my aquarium fish : (

why do we clean up the bottom of the pond? with a stream feeding my pond, i imagine my buildup of whatever will be faster than without one. i imagine decaying matter isn't always good, though i wonder if a layer of sediment isn't beneficial in a lined pond.

If organic matter is allowed to accumulate at the bottom of a pond, as it decomposes it will degrade water quality and contribute to algae growth.

I get a think nasty layer of "snot" during our hot summer months. It floats up during the day and then sinks at night. I can net the debris but this stuff is hard to remove.

Do you have a skimmer @tbendl ? I have a lot of loose algae that accumulates over the winter and once I start my pump it all gets sucked up into my skimmer and the filter catches it. It sounds like it might work for your 'snot algae'.

That is a good model but I really think for your purposes the smaller 10 gallon model would be more suitable. Compare the air flow (CFM) between the tow models. The 14 gallon model generates 2.5 times the suction as the 10 gallon. (135 cfm compared to 56 cfm.) 56 cfm will be less of an issue if you are concerned about the fish but still powerful enough to pick-up pond sediment. Fish normally avoid vacuums as it is foreign to their environment.

@Meyer Jordan so the smaller version is still out of stock and the larger one, shown below is available. I know you said it's a bit larger than what I might need but we are getting ready to hit "snot season" and I'm ready to buy. Do you still think this larger version would work? Maybe put a large screen over the sucky part to keep the fish out?

This size will work OK, but it doesn't have the built-in pumping feature as the model I earlier recommended. The difference being that you will have to periodically stop and empty the canister which can be a real PITA at times.

No that's ok, both sites are confusing so I wanted a second pair of eyes before I buy.
Do you know if there are any additional attachments I should look at or just plug it in and vacuum away?

What about a venturi type vacuum that's powered by a garden hose? Here's one.

It works just like a small gold dredge, here's the claims on the add for this one (costs around $20)
Easy to use: Simply attach the vacuum together and connect the vac to your garden hose. The vacuum works with the force of the water pressure entering into the vacuum creating a venturi action in which then draws debris and leaves right into the mesh net.

Simple design and easy to use.
Designed for use with a garden hose or 1-1/2 in. vacuum hose *(not Included).
Great for use in Vinyl, Fiberglass or Smooth/ Rough concrete-plaster surfaces.

Vacuum comes complete with: Vacuum port body, Mesh bag, Lower vacuum with 2 wheels, two types of pole adapters (Garden hose adapter and 4 foot thread together pole).
Vacuum is also able to fit on a standard telescopic pool pole with a 1-1/4" in diameter end. (not included)
