Got myself a new toy
And resulted in this:
Too much flow and the sands started blowing around (although being 1.0-2.0mm grains). Had to turn it to L mode and can't use the fancies because of the sand storm. And fishes seem to struggle too. But I am very impressed with build quality. The magnet is freaking strong too! So much for the brand-lovers......
Will try to find a variable DC unit to control the speed. That should solve the problem
