can the dunks be used in an outdoor wall fountain which is over 100 gal? How long does it take for them to dissolve? We don't run the fountain often

the actual mosquito donuts last a long time... the mosquito bits seemed to disappear a lot faster... I now use the donut shaped dunks rather than the bits, but they both are a wonderful product

The dunks will work just fine in your fountain even if there is fish its safe for them. They dissolve quite quickly as these are pellets which based on amount poured in it should last a month or so there is no measurement. You can also search for actual dunk donuts which are pretty much the pellets packed into a donuts these take more time to dissolve and will just float on top of the water. Good luck.

Yes, you could use a dunk for that, but I would recommend the mosuito bits version instead. Both dunks and bits constantly float on the surface and the bits are tiny enough to be virtually unnoticeable. The dunks are about 3" wide and about 1/2" thick. Either product has to be replaced monthly. Bits seem to work fastest per the instructions (results noticeale within 24 hours), but dunks definitely make a major improvement within a week. We use both, as we have both decorative fountains and large/small areas of standing rainwater on our property. Good luck!

If you don't run your fountain often, it becomes a haven for mosquitos; they like standing water. If you drain it when not in use, you have no issue. If you don't drain the fountain, then you should use the dunks. It is pretty effective.

Have only used the dunks in a bird baths. They dissolve quickly. Hope it works for you.

I put Epsom Salts in mines every use. About 12 times since getting it with 30-60 minutes each use.I run clean water with the pump on and empty it a few times to remove as much salt residue out of it.Everything appears to work the same as when it was new. Manual/book does not specify anything about using salts in it so do so at your own risk.

It depends on the setting. I have a small backyard fountain that uses this with a 200 gph pump. It produces a small, maybe 8" bell effect. This is fine for me, because I don't want a lot of over spray outside the fountain perimeter when the wind blows. For a larger effect, you would need a correspondingly larger pump. At low flows the bell effect breaks down and is unattractive.

So sorry, I can not help you on this. I would call a local nursery and ask them or contact the manufacturer. The water from my urns using this product is for watering plants - don't know how safe it would be for fish and don't think I would use it until you find out if it is safe for them. Wish I could be more helpful.

I agree with the other answers. Mine runs for approx 20 secs on a timer. There is only a top highwater float and not a "shut off float" at the bottom. Your pit is decent sized so there is a lot of water in it circumference-wise to empty in 20 seconds. It should not matter whether there is still water in the pit and indeed you don't want the pump to be running part of the time as dry. I'd rather have a little extra water than not enough such that part of the 20 second run time is dry. 4 inches in the bottom seems just fine. When it fills again the pump will turn on again.

About 11 Dunks worth, by my math: This bottle covers 2178 square feet and lasts up to 2 weeks. The Dunks cover 100 square feet each and last up to 1 month. So half of 2178 (because you must apply it twice as often) is 1087.5 square feet, which is about 11 Dunks. The dunks seem just a wee bit more expensive, but they're more convenient to use. On the other hand, if you have small areas of water, the bits are more efficient. On the other-other hand, you may cut up the dunks to use in smaller areas. My choice = both: Dunks for my tiny pond and Bits for the smaller standing water areas near my fencing.

We have used both in our stock tanks and rain barrels and they both seem to work well. Although the dunks seem to last longer.

I use mine in mineral spirits. Been submersed since i recieved it and still is working. I hopr for a long time. Make sure you krrp the pump submersed to keep iy cool.

Yes it takes about 30 sec. and it dissolves. I used one packet for a gal. of water.

Maybe 2-3 minutes. It does not take long at all. Of course, the more water in it in longer it takes. I think when it is at the max level it wold take 3 minutes.

I use half of a tall glass. If you don't get enough water it will not fully dissolve. Half a glass works just fine.

The directions say not to add anything to the water; addiyives may clog orifices where water bubbles come from. However, I have used white vinegar, peroxide, well dissolved epsom salts--not at same time--and works fine. I think anything that may build up residue as oils or gels might clog openings. I still love this footbath over the other two I had previously purchased.

Should be fine as a "dunk and rinse" as long as you don't let them sit and boil around. They may get a little softer, so I'd try to avoid deforming them until they've cooled for a few seconds (otherwise they make stay a bit warped). Hope this helps.

Yes they dissolve in water---I use it to make a normal saline solution. But they don't dissolve immediately so be sure to give plenty of time. Maybe prepare the night before. They are very hard and dense , about the size of a dime.

Outdoor stuff is tough because of all sun and elements they're exposed to (I used to build ponds and such). It may be marginally effective, but it would probably be high maintenance (filter will clog quickly, pump might get clogged). I'd say give it a shot. If it cleans the water you could always go with a better unit down the road.

It is not water soluble in the sense that you can mix it with water and spray through a garden house or a more automated distribution system. It dissolves fairly rapidly once broadcast over the ground, however.
