I have the 2100 on 20g lol.
Ill be doing a tank upgrade sometime soon and didnt want to purchase twice.
Still quiet they run on 20 percent surge 10s intervals.
What corals are planning on? If going sps dominate i would also choose the 2100 and decrease flow till sand storm is gone. 45x70 is 3150.
Yesterday i purchased the bluetooth controller for them. With this need the accessory pumps not full set. They are running a 50% deal on the bluetooth.
$49 + $168= $217 for 2 pumps app controlled.
They included 2 speakers for free, not sure if this is the norm or just for first purchases.
They make wave sounds for storm features, not sure why this is a feature tbh.
Forgive the wire mess i real quickly installed and didnt do any wire management or get rid of the wires for the ir controller.
Also adds a temperature sensor, so can see the temp of the tank from your phone when near enough for Bluetooth:
