just came across this....bit curious of it, seems like something i would like to try whenever i get back to some hydros....then again could be completely useless.....i have heard of people actually infusing tank oxygen into their rez and not seeing any benefit at all....so while DO does seem important, it seems a little more complicated that simply more oxygen = better.
anyone tried em?
any thoughts bout em?
seem to have some mixed reviews and not seeing anyone using them who is raving about em, pretty curious tho for sure..
