So with the recent tank change, I wanted to add random flow, instead of just constant flow. I was thinking about getting a Vortech MP10, but wanted to see if i could get what i wanted out of these for less than a third the price. Two 500GPH pumps, and the controller for about $75.
I was surprised when I opened the box how small these pumps are, they are about the size of a Koralia nano. The magnet is very strong for its size. I like the magnet compared to that of the Koralia. They seem to be very quiet, I don't hear any vibrations, or clicking upon restart....
Ive only had these running since last night, so time will tell.
