I just wanted to share that I love these newfangled controllable pumps. I was cheap (and am kicking myself now) when I started my tank last year. I started with a basic koralia pump to move water in my tank. I thought, koralias worked on my tank 10 years ago, so why fix what isn't broken?
Because pumps are soooooo much better now. I thought LED lights were neat after my long hiatus from the hobby, but I'm really geeking out over this gyre style pump. I got the Icecap 1k yesterday, and every single coral in my tank has responded positively after just 24 hours. The ability to flood my tank with movement then let it reset and repeat is phenomenal.
For anyone starting a tank or thinking of upgrading their pumps, don't hesitate. Get a wave maker, gyre, or other sort of controllable water movement system and your corals will thank you.
