I read in the other thread about that.
Believe me, I've tried every possible combination of plugging.
Plug in and out 4-5 times.
Plug and tilt.
Plug and wait.
Right now I am reattaching the hoses.
The hoses, Hydor, Reactor are all clear.
I think the problem is the outlet valve on top of the filter.
When I put the filled filter in the sink and plug it in, if expels water.
When I affix the (hoseless) lever/valve and depress the level, it expelled water only about every other time.
I don't know how to fix that, but I'm going to hook up the hoses, and cross my fingers, and see what happens.
If it doesn't work, I think I'm gonna bag it for the night.
Which would really stink, after all the cleaning, trimming, replanting, dosing, I did all day.
