![]() I also have another question, can I use the controller to completely automate my water changes once or twice a week? For example, I use two optical sensors (max and min). Then can I use the controller to open a solenoid valve and at the same time a water pump which will drain the tank (this will be at a set time, like 9 am). Then it shuts both of them off when it reaches my desired low point (min sensor). Then it turns on the return-line solenoid valve to fill up to max level sensor. Can it do this automatically? And do you know when you will have the plug-in dimmer module so I don't have to throw away my ballasts and buy dimmer ballasts? |
