Hello,
I recently was looking into dc return pumps also and was looking at the same three which are all good. However, after I did lots and lots and lots of research I found the current dc eflux 3500 gph far superior. I ended up going with that one for several reasons.
1.) cost, it’s a steal for the price of 229. Well that’s what I bought my first one for, now I run two of them for other reasons.
2.) it’s dead quiet and you will not even know it’s on. Plus it has amazing control and flexablity. You can also daisy chain it into your system with others, and it’s also blue tooth compatible as well.
3.) This pump can produce some flow. I run two of them now because I wanted lots and lots of flow. Hmmm oops.
I can’t turn them any higher then 15% or it’s just way tooo much. Even if I run one of them alone 40% is really pushing it and I have a 240 gallon tank, and a 75 gallon sump. So my water volume is 315.
4.) currents customer service is beyond anything I have experienced. They are very quick, friendly and if by chance you have a warrant issue, they are lighting fast.
Your list is really good also, but I wouldn’t count the current out. I came across it by mistake and have loved it ever since. I run two in my sump now and you can’t here any of them or any vibration and those are big pumps.
Hope this helps you, and if you think gosh why didn’t she pick one on my list, if I had no other options, the sicce makes a very good pump also. I have one of their pumps in my eshopps s300 skimmer, and it’s three times louder then my currrnt pumps.
It's still running today, just on someone else's tank.
