Pick up 3 unused sea swirls from a local member. I thought i just won the lottery when he offered them for FREE. Two of them are 1" and i believed the other one is a 3/4". One of the 1" is working without any work needed to be done, so i mounted on the tank to see how it would look. It stands out quite bit but i don't think it would be a problem once I built a canopy for the tank. The other two do not work, but the motors seem to be working so that's good news. This will work out perfectly, since i could use the two 1" for the main tank and the 3/4" for the larger frag tank.
looks like this one just need a good cleaning and replacing a few screws. Hopefully i could find similar screw without needing to modify anything.
