Hey there! I’m just getting back into reefing after an 8 year break, I currently have a fluval flex 15, for lighting I’m using stock + two additional 12” led bars, one blue and one blue red white mix. I’m wanting to keep sps,lps and a good bit of zoas. What light would be a good option that’s a bit lower budget? Also would a 2.5 gallon sump be a good idea to grow more chaeto? I have one of the back chambers filled with it and a light.
