Yeah I'm going to get the next nero 3 this week. So I will see what it says in the app when I get it.I have the Nero 3 for my 40, and I have two. I think it's smart to place it lower while you have that one higher! Will definitely make a great flow. You can also twin it (if that's the name on the app) to follow the first one (if you'd like).
I have the Duetto 2 ato and it works perfectly. I know the tunze is still a bit pricier, but if you're needing to save some cash for another piece of equipment you might be happy with the Duetto.
The fish and coral sales are gonna be my downfall. Man, I even have the text messages coming in, and while I don't plan on buying anymore right now, I still click the link to view themI'm my own worst enemy
I will say though on the fish side, I made an order with Dr. Reef back in February for my fish, and it took so long, I went through one tank, replaced it with my now 40, and did a full month cycle before they were ready to be shipped out. So, that's always an option. Plus, they came quarantined so it was just another step I didn't have to worry about. Make sure though that whatever fish you get that you see if they jump. Cause if they jump, you'll need a lid, and Kraken lids are expensiveeeeeeeee
I will look into the duetto. I was chatting with the BRS team on their site and they suggested the tunze ato. I am always looking at prices and finding a good deal lol.
Lid situation is a rough one. I can't find a lid for my tank
. Kraken doesn't even have it. I may have to DIY it also since I'm pretty much doing all HOB stuff. I keep looking at corals and going I want it but I'm nowhere near ready for corals. It is an addictive hobby that you just want everything and want it now. Makes you learn patience.
