shorty, I'm intrigued by your description of the sump pump pit and 'holes' Do you have a picture? So you have the sump pump plastic enclosure with the top on and holes are in the top (only? or in the top and sides?)

How do you keep it weighted down? And do you have extension poles holding the diffusers up 30" above the sump pump enclosure?

I have my diffuser in about 8'of water mounted about 10" off the bottom on a big plastic tote, with the height of the tote and the diffuser I'm probably 18"-20" off the bottom. I still don't know if I'm stirring up sediment or not.

I haven't run the aerator at all this year yet due to crazy amount of rain and also very cool days and nights and plenty of wind. The pond is very very clear (probably new water added and for the first time I added dye which is limiting plankton) But I do wonder if part of the clarity is that I'm not running the aerator at all.

Would love to hear the advantages of your bubbler in a sump crock idea and how you built it.
