My Eshopps sump only has 2 compartments so I can't really set up a refugium due to the skimmer being in one and my return in the other. I was wondering if anyone has tried throwing some lr and cheato in the overflow box to see if they'll grow in there. What would be the downside of doing this, I would imagine it'll be kind of hard to clean. My tank is a 90 gallon bowfront, so it's pretty tall, I think around 30". So I've got plenty of wasted space in the overflow box and I'm trying to make use of it. I'm still a newbie and I've never tried doing anything with growing pods, my tank has been running for about a year and a half now and it's my first sw tank.
