Hi, I was reading this thread:
http://www.barrreport.com/showthread.php/7392-Most-efficient-DIY-needle-wheel
I chose to drive my AM1000 reactor with a dedicated Eheim 1260 hobby pump (630gph) after reading comments here indicating flow rate would be more constant with dedicated pump, than if reactor was plumbed into canister.
I recently added an extra canister to increase overall flow/CO2 dispersion. Since then, I have been having trouble keeping drop checker nice light lime green - which I was able to do before adding the extra canister. My CO2 bubble rate seems pretty high for my size tank (>5-6 bps, in 90gal) so I thought I'd try to increase efficiency of CO2 rather than just keep cranking up the bubble rate.
Intention:
Do a needle wheel mod to the impeller of the 1260 hobby pump. (hole punch method).
Connect "false gas valve" from AM1000 to intake of 1260 reactor pump.
I know folk suggest bringing false gas line back to pump intake in any case. I seek feedback on whether what I suggest makes sense, or if I should just crank the CO2. Or, if increased efficiency would be minimal in any case and I should add 2nd CO2 line to internal powerhead (prefer not to, I've got a lot of junk in the trunk to hide already).
A replacement impeller is not cheap (>$100). And I would probably only rarely if ever service the the pump, unless there was a problem. I like the indication Tom provides that the 'cut & bend method' works well with mist barely visible, but a hole will not seal up whereas the bends seem to regress toward straight (requiring re-bending?). From above thread, it seems LOTS of TINY holes does well.
Thanks,
