Re: Anyone using ISTA Max Mix CO2 reactor??
Actually I helped with the production design/testing of the Mix Max designs.
I would say the problem you are having is too slow of a flow rate through the mix max and or too high of a bubble rate.
The Mix Max is very efficient and the bubble rate can be a lot less than what is necesssary through a glass diffuser. As well, if the flow rate of the canister or pump hooked up to the mix max is too slow (usually less than 300l/hr - example Eden 501 filter) then the problem you mentioned will occur. Also if the flow rate is too high, then the co2 will simply be pushed through the mix max befoe being disolved.
There are 2 designs, the small/Medium size and the large size. Small medium used for tanks 2 feet in size or less with a flow rate of ABOVE 300l/hr, and the large for tanks larger than that.
The turning over of the Mix max is only for the initial setup or after the filter has been disconnected for cleaning. In most cases it is not necessary as the Mix Max will naturally push the air out of the Mix Max after 24 hours, but it will prevent the extra noise and reduced diffusion rate for Co2 in that 24 hour period if you can turn the Mix Max upside down while running to quickly displace the air in the Mix Max.
Once the Mix Max is hooked up, it is basically run and forget about it. If used with an inital tank the Co2 bubble rate has to be adjusted as the plant mass increases ofcourse, but other than that there is nothing to it.
