Lol, that was probably me in a previous thread. Masterflex continuous use peristaltic pump's are typically used in lab applications and don't burn out like hobby grade ones. If you get one get the brushless because they are silent. Typically can find a good deal on eBay. I'm currently running one and there awesome.
If you control bubble rate and Effluent flow your pH states rock solid and you could melt exactly what your tank needs
