Hi Terry,
Yes the Geazy was made out of the original Vortex that was made by Dave Arnold and he came along and we converted it and Ive gradually modified them as Ive gone along,it like an ongoing project to see if i can improve my water quality
The static K1 stop nearly everything it does a great job,when we first converted it i thought i had a fairly clean pond (don't we all) but the K1 actually cleaned it even more as i could see the difference in the TDS
Its so easy to clean and you don't get wet hands either i just cover the two transfer ports isolate the pump and bottom drain and then turn on the air,leave it for a while then drain to waste and i do this a few times i also jet the hose on it sometimes to make sure its clean
The TT is in my shed and is insulated so you cant hear anything from it at all....well perhaps a dribble but basically nothing
K1 is a great media and performs very well i have been baby sitting a couple of Koi this summer and the guy who had em was a bit tight with food (sorry Andy lol) so i decided to feed the poor things up a tad so increased thew feeding and even the wife was throwing food in so much so i run out of food and had to borrow some from Bob

I am not 100% sure but i had two 15kg sack of food and the only lasted just over a month so i think the filters seem to be maturing well
