My Rena 400 is dying and parts are scarce.
It has two outputs -- looks like each output is its own internal pump. The specs were 2 x 200L per hour, 8 watts, 2 x 4-35 PSI. I can't find a graph that specifies that by depth ....
I'm considering buying an Alita Linear Air Pump -- the AL-6A. The AL-15A isn't much more expensive and the decibel rating is almost the same.
Most people seem to use these on multi tank setups -- I have a single setup:
- About 50 gallons, plus an external sump.
- A couple of bubblers in the sump
- A bubble wall about 4' long in the tank at a depth of about 16-18".
Is the 6A already overkill? I'd rather not be spending the watts every year (which cost more than the difference in price between the two!)
