    Dolphin AV-150 Question

    Looking to buy one but the specs says it is for indoor use only and should be installed in a clean and dry place.

    Where does everybody put these?

    Mines in a garden shed. I think they just don't want you leaving it out in the weather.

    outdoors in the unsheltered filter pit right beside the Airtech 120s.

    Just keep them out of standing water.

    I have never kept an air pump out of the elements....just not in standing water. that is why I purchase air pumps with cover screws on the bottom. No way for rain to get in. And the cold air or winter helps cool them. Heat is the enemy of the rubber diaphragm. In the winter the air pumps product a nice layer of warmer air beneath the floating solar cover. Works for us. Of course if you keep them our of direct sunlight there will slower aging and fading from UV exposure.

    Also, what is this I read about too much air and nitrogen? And how do I know how much is too much?

    I'm afraid my 2000 gallon pond might end up more toward 4000 gallons by the time I'm done digging by my measurement calculations. Won't know for sure until doing the salt method, but I think definitely more than 3000.

    You can get all manner of covers for swimming pools. One type looks very heavy duty bubble warp. It comes in clear, blue and maybe other colors. For use with a pond...you want clean so the fish can get some light in the winter. I simply float it across the pond surface (bubble side down) and drape it over the pond walls. One more advantage of having a semiraised pond.

    SolarCovers.com - Clear Solar Covers

    The air domes run 24/7 and keep delivering a nice "warm" layer of air between the pond surface and the cover. I say warm because air pumps cool them selves with the air they push. So that little bit of extra warm goes to insulating the pond.

    If you live in a climate where there is serious winter....move SOUTH. If that is not possible, you may need to build a structure over the pond to take the snow load. I leave that to folks who live places where they gonna do that.


    Too much air sounds like the too much filtraiton old wives' tale. Both usually come out of watergardening where they do too little of both. Short of knocking media outta the filters, or fish out of the pond, you can not over aerate. But...there is always at least one....in winter you do not want to super chill the water by running waterfalls/weirs/showers/TTs (depending on your climate). Even here in Atlanta I will stop the showers no later than December 1 and just rely on the Nexuses until around March 1.
    Koi keeping is not a belief system; it is applied science with a touch of artistry.
