I'm thinking of getting a mighty jet XL, but have not read any reviews on it.
It is a typical chinese pump. They work great, the last as long as any other pump out there, unless you buy the top of the line DC return pumps which are way overpriced for what you are actually getting.
For what your doing look at the Jebao DCP 10000 its half the price and has the same reliability as any typical DC pump does. The thing is at 120 bucks, if you do have a problem its not a big deal to replace it. I went in with this attitude and bought another one for back up. Ive been running it 5 years and its been as good a pump as you can get. I have had zero issues with both my jebao pumps.
I run the DCP 10000 as a basement pump, and I run it at 45% and its under 50W verified with killawatt and its more then enough for my 210 G display tank. I use the small baby jebao 2000 on my Calcium reactor, and that pump also has zero issues and it was like 50 bucks.
If you went AC you get the best and buy an Iwaki, problem was mine was using over a 100W which means running it 24/7 and my Jebao literally paid for itself in a year of operation saving me electricity.
So a good Iwaki will last decades, they are industrial grade pumps that are bulletproof. Downside is AC cost for long term use. Im in this 30 years so far, and dont like throwing money away to power companies. These tanks are expensive enough.
Problem with DC pumps is they all have reliability issues vectra we see a lot of failure rates since they are one of the more popular brands. Red dragon and another german pump are reliable but they think they are made of gold and run 600 bucks PASS hard PASS. Jebao have literally sold tens of thousands of these pumps, and you dont see hardly any failure threads, some of their first couple of years and models had weak links which they have addressed as they evolved forward. So for the money they cant be beat. There is even an american company that buys them and renames them and offers a warranty at a higher price point, pass on that, if you go that direction look for Simplicity I think it is. Better off just getting one of ebay or
amazon, and having a back up.
No matter what DC pump you get, make sure you take the impeller out every 6 months and soke it, to remove calcium build up, and you wont have to replace the impeller.
Above all you want adjustability so you can fine tune flow to your system. Otherwise you will end up withj not enough flow, or too much and too noisy
