Well, I'm still planning for this tank... although, with planning an upcoming move and an upcoming wedding, the tank has been, shall we say, somewhat relegated to the realm of the "less important". Anyway, I am giving it some thought whenever I can.
Thanks for the filter suggestion, shrimpNewbie, but for the moment I am still leaning towards dual 2217s.
I plan to have one of the 2217s serving one side of the tank, with a Hydor heater and Rex type reactor on the outflow. The plumbing on the other side will be a little more complicated. With my limited Sketchup abilities, I seem to have come up with a plan for semi-automating my weekly water changes with the turn of a few valves.
(The tastefully colored circles in the pic represent ball valves/ unions.)
Water will enter the manifold (outflow from the Eheim) on the left of the diagram. I'll try to minimize 90 degree bends in the plumbing, but I think that the complexity of the plumbing may necessitate the inclusion of an inline pump, which should improve the flow from the 2217. I'm open to ideas as to which pump would suffice.
I'll have access to hot and cold water outlets which will be hard-plumbed under the tank stand. I am still thinking of using Hoppy's idea from this
thread to mix the hot and cold water (I'll be looking to minimize the amount of hot water that enters the tank straight from the hot water heater).
I would like some input as to whether I would need to move the inline pump to the right, so that it comes after the addition of the water that will be entering the tank on water change day.
Finally, by opening up the "drain" valve, I should be able to drain the tank quite easily (I suppose it would drain faster if I included a valve next to the Hydor and shut it off when changing water).
I'm relatively new to planning loops and such so I am open to any and all criticisms/ comments
