Hello and

to TR. I use a 24" Solaris on my 54 corner with good results.
I think it looks like you have bio-balls in the
sump. If so you will want to pull them before you start adding corals. Bio-balls do a good job converting
ammonia to
nitrite to
nitrate but it stops there. Fish do fine with some
nitrate but corals aren't happy with levels about 10.
