So the pump that came with decided to crap out. Picked up a 395GPH submersible pump off amazon for $15 bucks and some new 1/2" ID tubing. Gotta say I'm loving the results. Flow is obviously better but not over the top.

So you're running the pump externally to the same canister? Pretty creative thinking.

I have done this on a shrimp tank I had. It does work great! To help me with cleaning the pump due to it catching some dead plant material I got a sponge filter for a pre filter. It also gave the tank more media for the biological side. Making cleaning the pump itself only once in a while job.

Or if you want make your own. Think you may like doing this. As a pre filter my after market pump lasted for years, just an idea , may work for you if you like.

I also do this for two bird baths I have and save me on buying a new pump every other year.

It had an external pump to start with. Just a week little 290GPH one that didn't last long.

What you have now look's ok and doing the job. Just make sure if it goes out one year that you find one that can handle the rise , looks like it travels around four foot up. To me , I think that's what kills some aftermarket pumps. We sometimes forget about how far the water has to rise. In my beginning I went through some impeller's.

Most definitely. At $15 a pump I can live with buying a new one every year. My biggest concern with the higher flow rate was possible leaks at the filter. But a week in and still no leaks!

That is great! Had my share of leaks over the years.
