I confirmed the level to which I have an aquaria habit this weekend by spotting out that someone having a garage sale had a Magnum 350 in thier front lawn, all this while driving by at 45 miles per hour.
Said filter was acquired for $15, needed a new magnet on the impeller shaft. One LFS has said magnet and wanted $30 for it, Big Als wanted $21.99 for it.
I went to my favorite LFS and they hooked me up with a spare impeller shaft and magnet from a 220. Slightly smaller magnet and shorter blades on the shaft.
I tried this one and it did not work right, but then I took the magnet and with a little dremel tool work retrofitted it onto the 350 impeller shaft and POOF, it worked.
Now my actual question, do you guys think this would be a good filter to use on a 100 gallon heavily planted tank? With half the flow going to a biowheel and half through the c02 reactor? Any experiences?
