so...Im starting to make some moves toward my 40gal breeder (hopefully final tank) and starting to collect some info and some ideas
currently, I run an inline diffuser (boyu, $4 china direct
) but Im thinking about going the rex grigg diffuser route in the future...
so Im wondering...has anyone ever considered connecting grigg style reactors in series? well...not series as in stacked exactly but in series via tubing, with them being mounted parallel to eachother
I could see some benefits as the 2nd (or 3rd possibly) reactor will catch any escaped bubbles...but wouldnt they just eventually escape as well?
has anyone tried it...or is it just overkill?
also, found some interesting research lately about terminal velocity of CO2 bubbles in water...its ~25 cm/s for bubbles 4-16mm in diameter ...which is all well and good...but when you think about a 35 gph filter running 1/2" hose (eheim ecco 2232 on my 20gal)...the water is already moving in that line at ~38 cm/s...which means not much change in diameter is needed to make an inline reactor that stops the bubbles in their tracks...jumping up to an 1" diameter pipe would work (theoretically)
anywhoo...I digress (love being an engineer) anyone tried a series grigg reactor?
