Yes with 400l/h small pump and on the pump output a hose, which have 50 micron filter sock. On the intake hose attached to rigid acr. pipe5mm ID 7mm OD (3'' long enough to keep it by hand for hard to reach places) and the end is 45deg bend with teeth to scrape easy from the LR whatever I want. Algae, ciano, and it work well for vermetid and aiptasia for me. Suck it all and filter the water straight in the tank, sometimes in the sump. For the aiptasia I put the rubber typ end from Rigid pipe spot feeder, and suck the aiptasia straight out of the tank, some times have to repeat the process 1-2 times but after no aiptasia on the near areas (turn off all pumps to can suck it completely w/o leaving tentacles or aiptasia matter to flow away and reattach to grow).Anyone made a setup that sucks up the algae/crud but immediately returns the water to the tank/sump?
