Thanks again for all the help. Now I have another question....the pump was delivered last week, got it installed last Friday and have had it running 24/7 since. Noticed it sure runs hot....in fact, too hot to handle. Is that how it is designed or does it require a cooling fan....did not see any comments to that effect from any of the other posts.
I have some pictures, but since I do not have a web site to post them to and since this BB does not support image attachments, will just have to describe the set-up. The pump is in a shelter I constructed of lumber scraps. It sets on a 1X6 with at least 1-2" of space on either side of it which is completely open underneath. The shelter itself has about 4" of space above the pump with venting of at least 1" running all along the top edge on both sides. Seems like that should be adequate venting, but noticed that when I kept the lid open, it did not make any apparent difference in operating temperature.
As for the operation, it is producing a steady stream of bubbles in 7-8 feet of water through 2 12" airstones that I had left over. Figure those should get me through what is left of the summer until I can decide on a more permanent solution.
Again, any comments regarding how hot the GAST pump runs would be appreciated.
Thanks.
