Had a bunch or trouble trying to decide how to do the res for this but I sealed the connectors onto my temporary solution tonight so I will be flushing and leak testing tomorrow....maybe some pics of that and what got done so far. By next weekend should be up and running and then I can give some details of temps, flow, power used by pump and fan....all that sort of stuff.

I have been wondering, with your setup do you see much fluctuation in the temps from day to night? I have been looking into adding a 45 gallon barrel (as a res) to use as a kind of heatsink as it would take longer to heat up more water during daytime on hotter days....

Maybe something to play with around July or August
