[Wet Thumb Forum]-My Magnum 350 adventure this weekend.

[Skippy]

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?

Good find!
I would leave the bio-wheel out, and still think you might
need another filter for more circulation.

For a 100 gallon tank you would want at least two Magnums. If for nothing else to avoid dead spots. The one good thing about Magnums is they make awesome CO2 reactors by themselves. Just put the CO2 into the intake and away you go.

I'm not fond of the Magnum series as filters as they have a very low media area for the amount of water they pump. They load up very quickly IMHO. I prefer cannister filters. A Rena XP3 would be a great addition to your tank setup.

I'm a big fan of water movement. On my 55 gallon I have a Rena XP3 with spray bar, a 170 gph power-head, and a Bio-Wheel Pro 30.

Well...

I already have an emp400 and 125gph powerhead on the tank (powerhead handles c02 diffusion). My pondering was if I could remove those, although what I am thinking now is to remove just the powerhead and use the canister for c02 and leave the emp400 on it.

The 400 has a small noise to it, but I think if I tear it down for a good cleaning i'll be able to rectify that.

The 400 is currently to the right side of the tank, I was thinking put the intake for the canister to the right of that, then the output frmo the canister on the far left side of the tank to force some water flow.
