Light dimmer to control powerhead?
About a month ago I ordered a SEIO pump from Foster and Smith. I liked that one because it was adjustable. I showed up, and after getting it installed, I decided within a few seconds that it was unacceptably loud. I sent it back to F&S for an exchange for a Koralia 1. Those are on back order, so I opted to exchange for a Koralia 2 instead. It's a nice pump. It's quiet, looks to be great quality... however; that thing moves some water! My school of 10 black neon tetras seem to be able to do nothing swim for their lives to keep from being sucked into the back of that thing.
I"ve already spent too much on shipping to send it back again.
Is it possible to use a light switch dimmer (thyristor) to vary the 'power' to the Koalia pump? Any other ideas?
Also, Koralia makes different pumps for always-on, and pumps for wavemaker applications. The normal pumps are not meant to be turned on and off repeatedly... Can I put this on a timer and turn it on and off ONCE a day?
