Nyos 160 skimmer cup drain off mod.

[atoll]

The Nyos 160 comes with the facility to attach a supplied tube to the cup to drain off skimmate. However, the distance between the cup bottom and the shoulder locking end of the cup is quite small resulting in a kinked tube when fitted. This is not good and also means the tube can easily come adrift with the skimmate draining back into the sump or worse.



My solution was to drill out the nipple the tube attaches to and fitted a RO elbow connector I had from a dismantled RO unit. I had to file down the thread of the elbow almost smooth and glued it into place with some Unibond extreme glue. I also fitted a tap to aid draining of the cup. I know some people will say the cup should be removed and cleaned rather than simply drained but there are times when you just want to drain the skimmate off.
