Personally I prefer not to T-off the main return pumps for reactors and have always used a separate pump for the various reactors - ATS (2000 L/hr) , Rowa reactor (~ 300L/hr) , chaeto reactor (1000L/hr), calcium reactor, De-nitrate reactor etc. Got the Vectra S1 about a month ago. Quite a small pump & rated for 5300 L/hr. Piped up for the various reactors. Configuration note : Both return pumps go into feed mode when triggered - i.e. flow rate slows down to a point where no water flows to the overflow or siphoned back through the return pipes. This ensures uneaten food remains in the main tank as long as possible so that fishes/corals can get to it instead of being filtered away. Helps keep the overall water cleaner as well. But the reactor pump is to remain on all the time (do not want it to go into feed mode). To enable this on Reeflink, you will need to create a new profile (i.e. add a new aquarium), then add the pump. Hence the trigger behaviors can be differentiated. Main return pump , Backup return pump, Reactor pump. The Vectra S1 is just as solidly built as the bigger M1 pumps. I think its perfect for smaller sized 1-3 feet tanks or for freshwater tanks which may not require such high flow requirements. And of course, a good reliable pump for running various reactors. Its also a good sized pump for those thinking of using it as a closed loop pump to eliminate dead spots or unsightly wavemakers.

Move it away from the light a bit and see if it helps. Also, leave it alone for longer periods of time, they usually don't like being touched. Sent from my E6653 using Tapatalk
