ah icic, good point.. actually I'm using a small submissive pump to generate the inflow instead of the designed air-pump (which has really low turnover), so I'll just monitor this pump, from the looks it seems to be able to generate sufficient turnover, but it's adjustable so I can rev it up anytime too.. very handy breeder box since it comes with inlet, outlet, and lid.. didnt really modify much except to hook up a powerhead instead of air..
thanks bro peacemaker, will have much to learn from you in future.. btw these fellows are fairly nocturnal explorers I realize.. interesting..
