TUNZE 9430 Skimmer

[Macca_75]

I run a 6mm (1/4") JG tube into one of the air holes (has to drill it out slightly) and use a liter meter to pump 2L/day out and into a waste line.

Not the same as a drain line, but does the same thing. If the skimmer ever went nuts and produced more than 2L skimmate/day or the Liter meter failed then the cup could overflow. I could overcome this by adding a float switch into the lid to kill the skimmer should the cup fill I guess.

Cheers for the reply Macca !!

Nice idea.

I was thinking either an in line pump through the lid activated by a level switch, or drilling a hole in the cup at a level just below the top of the neck so that it would only drain when the cup is full..... I just want a back up for when I'm not home for a few days.

Cheers,

Gab

Just be sure to buy a good plastic drill bit, with standard drill bits it can crack, plastic drill bits tend to be a "coarser" pitch and very sharp.
