What pumps did you switch from/to?
I am pretty pleased with a 43 Watt draw... but I am interested in going with a bigger pump when I move to a bigger tank. I would like an efficient pump though.
I used to have all these cheap asain brand pumps and a few sicce- sedra pond pumps drawing 180-250W each. Now I use laguana for bigger pumps 100-160W and aquabee for smaller jobs 13W.
I will say the siccie sedra did have MUCH better head height but the laguan works great at a low head height and they last for ever.
