I'm in between 2 options for my 155g tank.
I can either go one large - possibly 40 watt Aqua Ultraviolet Classic
OR
I can go with 2x 15w HOB advantage filters with 2 different speeds - one for algae and one for other stuff.
OR
I can do the 40 on my 155g DT and I can run the 2x HOBs on my 20g QT tank and my 30g Observation Tank.
Decisions, decisions.
