Yeah, i did take a look at their glass skimmer & overflow when i first started saltwater tank. But it is too pricey for me haha. Besides, glass looks nice until covered by algae. Maybe i'll get another Tunze 9001.
Will be aiming up towards surface to minimize sandstorm. But yeah, have to lower the water level.
Thanks, at the moment flow from the return is pretty strong. Maybe get Tunze nanostream 6040
