Tim, I've contacted Dave and he's been great it just seems that more and more people seem to be having magnet problems and I'm sick of packing my pumps off to send to IC. I bought the pumps to be on my tank not heading back and forth through the mail. It's a PITA.
I don't want this to turn into a b%$ch session or highjack someone else's thread, all I want is for the product to work as advertised.
I sent all 4 of these units back to IC to be refurbished to as new condition before I put the new drivers on and paid about $250 for that. I get them back and they don't stay on the back of my tank which is well within the thickness tolerences at 11/16's.
I specifically designed my tank for this product and was one of the first on board because I didn't want CL holes in my tank and all the associated plumbing, pumps etc. I didn't like the bulkiness of the Tuzes either and now I can't place them were I want.
After spending over 2g's for this equipment and associated repairs and refurbishing I'd just like a product that works as advertised that I can put in my tank and do simple maintenance on, cleaning every 4-6 weeks and enjoy my tank.
