Obviously I do find it necessary

I can make more money, but not more time! There is also the enjoyment of designing and building it. I enjoy my fish tanks but I don't want to spend hours and hours working on them every week. I've just cut a huge chunk out of my maintenance time. It'll never be maintenance free but it's about as close as it can get - as far as I know. If I could figure out a way to clean the gravel and filter automatically I would

Any one have idea's?
I'll keep feeding them myself, I like that part.
I totally agree with you!!!!!!
I am doing close to the same thing you are and your right...it is very enjoyable designing the system and making it work!!!!
My differences are: first of all I have 8 drains(holes) on the bottom of my tank...I did this to combine a water change with a gravel vac and evaporation at the same time.....
in order;
1) mixing valve 70f to 150f (smallest range I could find)
2) Canister filter(type you install under your sink)
3) Chemilizer mechanical chlorine remover filter
4) Rain bird irrigation pvc valve(24vac)
5) RTD(remote temperature device)( to keep the temp. set in case
my hot water tank can't keep up)
6) Rain bird valves before the tank and the sump
7) level switches in tank and sump
8) another 2inch valve from my 8 holes to my drain(teed together)
9) all the wiring goes to a Allan Bradley PLC controller 1500
Sounds confusing but in a nut shell that is my fresh water system,
my gravel vac system and my evaporation system combined....
A real challenge to say the least but lots of fun!!!!!
Can't wait till it's done.................
