My system is a Thomas 2660 pump with 450 foot of 3/8 air hose run underground. Then 100 foot of 5/8 weighted hose with a single 4 foot colorite ring type difuser. The diffuser is zip tied to a road sighn sitting straight on the bottom. I have a Gauge on it and at about 8 feet it is running 13 psi.
My pond.. It is basically a round pond which is .35 surface acres. Max depth is about 9 feet with an average depth of roughly 4 1/2 to 5 feet. It has a heavy load of fish and I feed heavily also. I need to work on this this summer. I have cnbg,res,cc,lmb and 1 grass carp.
My concern.. I got this system on the cheap about 5 year ago and it has served me well but as I learn more I feel that's what I have a cheap system. The diffuser I think could be better and my psi concerns me. My first pump lasted 3 years. This is my 2nd.
My goals.. I'm looking to have a system that will keep as much o2 in the water as the temp will allow. I was also thinking about putting the system on a timer and only running at night to maybe manipulate the water temp a couple degrees in the hot summer. If this would be possible.
So what do I need to look at changing in my system?
Thanks
