Yesterday I got my new Sunsun HW3000 in and today I have it set up for a test run in my garage on a 29 gallon tank. I will let this run for a couple of days to make sure it is working ok and doesn't leak. So far so good.
One of the things I am really interested in is will this new canister heat up tank water the way the old one does. So I have a thermometer setup to measure the temp. The temp starting out is 71.5° F, so I will look at it again later to see if it is heating up. One should expect some increase in water temp, simply because of the pump pushing and pulling water through the hoses, which causes friction, which causes heat. But this should be very minimal increase in temp maybe one degree, I will see. But that is all just guessing on my part.
Since this canister filter has four large trays, I am using the bottom two for sponge filtration. I will fill the top two trays with the bio-home media from my old canister filter when I replace it with this one.
So far I am really liking this pump, much easier to prime then my old Polar Aurora where it is primed by pushing a big button on top. Of course I had to fill up the canister itself with water before setting it up. Then all I had to do was fill up the intake tube with water (I used a plastic water bottle which took about six refills to fill up the hoses). Plugged in the canister and it spit some air out, not much, but then pumped water.
One of my complaints is those green hoses that came with it. These are only 5' long, not nearly long enough for me to use. The out take side is ok in length, but the intake side needs to be 10 feet for my setup. I setup the canister filter in a large plastic container off to the side of my aquarium stand and have to run the intake the full length of the tank and then some to reach. I ended up buying a 10 feet long clear plastic hose from Lowes that seems to be working great.
But the Sunsun HW3000 has some great features like being about to adjust motor speed and hours for the UV light to be on and off. So for now I am really like my new canister filter, but time will tell if my feelings on this change.
