you could also decrease the distance between the fan and the bottom of the reactor.
hey DJ I知 not 100% sure what you mean with your suggestion to hinder the wearing however I have a pretty good idea of what your saying the used fan does not produce much torque so I知 very limited on what I can do, with the addition of kalk it makes start up at times tough at first so I知 worried if there was any more mass( such as props) it would not spin freely. The reason behind choosing a lab grade stir bar is because it is made to withstand extreme pH conditions and not deteriorate long termthe fan is DC I知 currently using 3.5v I tried 12v and 6v but the initial speed was so much that the magnetic bond between the stir plate and the stir bar was broken and the stir bar would just shake around all over the place while the fan turned crazy fast. because I知 already using such a low voltage it limits my controllability big time if I have it turned down to low there simply isn稚 enough torque and it won稚 spin too much voltage and I run in to the problems I mentioned about earlier
what if you used a rod or pvc pipe for your stir plate drilled the centerof it and used a nylon screw to fix it to the bottom and reverse the poles of the magnet so it pushed the stir rod up instead of pulling it to the bottom that would fix the acrylic wearing and shift it to the screw that would be easy to relace if worn. you could also attach some flat stock at a angle to make it as like a prop. if that fan is dc a pot would be the way to go for speed control. Alsp found a pretty good site that had a diy on keyhole flanges ill try to find it again if your interested
Welcome aboard, greetings from Vancouver. Happy reefing!
Hey Shawn, my name is Daryl and I am from St. Catharines (Niagara). Nice to see the progress.
nice to see another local on here.
