Colleagues, please help: 1. What do the regulators control? 2. How is THIS configured? 3. What exactly should we achieve as a result? ............ And where should the pump itself be installed? It is currently positioned at the top, at a depth of 10-15 cm near the front glass. ............ I understand that this device works like a running wave - it sequentially activates the channels.
