Hello,
I run two current 3100 gph dc pumps on my 240 one per overflow. They have been amazing and the customer service and warranty is fabulous. I have had mine 16 months and to be honest this weekend will be the first time they get a vinegar bath. Still only run them about 65-70%, but you definitely know when you turn them up to 100%. The price point on these is also really nice and they are Bluetooth linked as well. Even at 100% they are dead silent and they do an amazing job.
It’s nice to reach out to get an idea of what others use. What most don’t realize is 95% of all this equipment is made in China, or assembled, or something, but designed and stationed here in the states. Anybody can have a gorgeous beautiful reef tank when you spend tons of money. What fun is that? It gets more fun when your tank looks as good as the one where someone spent 30k on, and yet you spent a third of that or less. Have some and experiment, (sometimes things do kinda suck, but the experience you gain from it is priceless. People by super expensive return pumps (because they don’t want it to fail). Well what happens if it does? I spent 1200 (example only), and it failed. At least when they do fail, you know what to do and faster at it. We can always blame equipment, but 75% or even 80% it fails because we become too dependent and or complacent.
