Tunze released an all in one kit that will handle most reef aquariums. The Tunze skimmer kit 15 includes sump, protein skimmer and Tunze’s famous osomolator auto top off device. The entire sump system is 21 liters including a lid or cover to prevent salt creep and humidity while holding a total ofÂ 21 liters (5.5 gallons) of water volume. The system retails over inthe UK for a hefty Â£504.80 ($730), but that is the price to pay if you want a slim, all in one sump system with auto-top off. We don’t know when this willÂ hit the US market but don’t expect it to be that much longer, right Tunze?
