DIY water polisher

I picked up an under-sink filter cartridge to try and fashion a water polisher. It's about 9" long x 2" diameter (). I found two rubber corks that perfectly plugged each end. I drilled a hole in one cork large enough to shove the output of a powerhead into. The powerhead is firing into the inside of the cartridge, and it does not work. The powerhead does not have enough pressure to push the water through.

So, can you guys check me on this? If I combine this beefy pump with this filter housing, and appropriate fittings, will the pump properly shove water through the filter like I'm thinking it should?

Im thinking you will clog the filter pretty fast.

That's the point. I have normal mechanical filtration (and a bamboo shrimp). This is to filter greenwater. Replacement 5 micron filters are relatively cheap.

Not really sure on the application here. A Shurflo demand pump is what I use to transfer water from my RO tank to the aquariums but never checked the duty cycle of the motor. (continuous or cycled run/rest time for the motor)

If you use it in cycles trapping organics I would think the trapped material would go foul between uses.

I had a tank filtered by a set of these filters. Mounted under the tank. With an on/off ball valve it was a breeze to maintain. I used a mag 7 with mine. What micron size are you using? Maybe go a step up. I used the carbon cartridges, along with the prefilter sediment and fine ones.

You're also using a 60W pump. I'm using a little Penguin 550, which has about 2 feet of head on it instead of the 10+ the Mag7 has. I don't know how many PSI it takes to make the filter flow, but I'm guessing it's more than I have. I'm using a 5 micron, the next size up at the local hardware store was a "sediment" filter, with no clearly defined micron size.

*sigh* I'm about to just get a Vortex and call it done.

Be careful with the vortex. They seem to be very hit or miss. Many people really have bad experiences with them. Seems recent quality might be down. For the money, a magnum 350 with micron cartridge or the HOT magnum with micron cartridge makes for a pretty good micron filter. You can even make it better by wrapping the sleeve with filter floss.

I really liked my filter setup, but do not use it any longer since that tank is gone. 5 Micron is really, really small. HD and Lowes sell 20-30 micron size filters that you might be able to use. The sediment filters are dirt cheap too. Check walmart as well.

Will a 20 micron filter get greenwater?

I think a 1 or 0.5 micron filter would be better for greenwater. The smaller the number the smaller particles it traps. I diy one of these housings with a mj 1200 and worked out just fine. I only used it after rescaping to get those floating particles. I used the 0.5 once for gw and it worked. Had to do it over a couple days and change the filters a couple times.

might be cheaper to go UV for green water

That's what I did. it was for a feeder tank, so it sees very fluctuating ammonia levels and potentially ich. I guess a UV thingy will do the same.

Problem was it's not as gadgety since I already have UV stuff

I've done something similar in a fish only tank a few times to clean up green water. I took a string wound 1 micron filter I found at Walmart and fitted it onto the input to a powerhead and plugged up the other end and dumped it in the tank. A few hours later, clean tank.

Be careful removing it later or you will dump all the green back into your tank.

So the problem was that I was trying to blow water from the inside-out of the filter, rather than draw it from the outside-in?

Filter on the input worked for me.
