Well they worked fine, my problem was getting a good pump to run them. The tank was setup in my bedroom and the water pump i was using was so loud i couldnt sleep....
my other problem was finding a place to put them. I had them just sitting on shelves, but 5 gallons is alot of weight for a shelf...
I dont have any space above the new 90 in my basement (in fact i cant even make a hood that opens upwards) so I had to scrap the surge buckets.
When i setup another tank I will be sure to include them. There really is no other way to create water movement like that.
Oh and BTW, if i setup the surges again i wont bother with half that crap aquatouch does. Just get a toilet flush valve and a ball float. You could find some plastic ties with either one. Just zip tie the ball to the flapper, and set it for what size surge you want.
