Your system is very efficient indeed. It will handle more load easily.
BTW now you cant close your case, there's a tube going on the side

Tsss.
Interesting to see how efficient a system can be with lots of elbows and 8mm tubing...
Aquacomputer blocks can be bought with chromed 'straight' barbs, which i prefer a lot over small 'quick connect' ones. My two twinplexes have those and Tygon stick to barbs so well it cannot be removed...
Aquatube is nice and all, but too expensive for what it is - just an airtrap. But i must admit it's a looker.
