Posted by Ian_m on March 14, 2005, 7:45 am Please log in for more thread options Are there any problems in putting the air-pump on my Juwel Vision 180 on a time clock ? (I already have the lights on 13hours on a time clock). Reason for asking as I often turn the pump off in evening anyway so can watch/listen to TV with out and hum and bubbling. I was thinking of off overnight till say 12:00 - 7:30am (allow fish to sleep ????) and off for the evening (say 8pm to 11pm). Pump + heater obviously left on. The filter pump (600 lph) causes quite a lot of surface current so lack of air bubles shouldn't be a problem in the time it is off.

You don't need to supply air to the tank if you have a pumped filter. It provides no benefit whatever. Just turn it off and leave it off. The only tanks I have with an air pump are the fry tanks in the Fish room and these have air driven UG filters. My oldest fish has now been without an air pump on his tank for the last 20 years - it doesn't appear to have done him any harm.

All the fish poo and other organic yuck gets lifted into the water, by the currents created by the air and taken away by the filter.

Just a thought, Rob Posted by Ian_m on March 15, 2005, 10:11 am Please log in for more thread options > The only thing I can think of is that if the pump is lower than the tank > then the water could syphon back into it... > Got one way valves in the air lines. Yes the water does syphon out, one of the old valves I had was blocked, so got a replacement, but the act of disconnecting (pulling the pipe off) it caused water for start syphoning out !!!!
