I just bought a IM 170 because of your channel, lol I know copy cat. I decided on going with a CaRX for a set it and forget it approach, but I am going to get the Luna ecco 4418 that’s 44” long so I can have enough room for a reefmat 1200 (cause I hate changing socks), algae scrubber, and my royal exclusiv 200 and the aqua uv 57. I’m probably going to follow your lead on dosing NO3 and possibly a CO2 scrubber/kalkwasser for PH but the Carx might take care of that all together?. However, I am going to run a little coral grow section like yours, what light are you using over the sump for the mini corals? Would you change that light and use something out for whatever pro/cons you have seen? Also, are you doing regular water changes? I would like to try the “no water change” approach as I know a bunch of people have had good success and I’m in the road a lot, so trying to automate and simplify where I can. If so, what would you recommend dosing for the above mentioned setup, I’m guessing Mag, minor and trace elements? I would imagine everything else would be taken care of. For lights, I would love to ATI Stratton but no way can I justify the cost so I’m thinking the photon v2 50’s or 3-4 reefi uno 2.1 pros since they are PAR monsters, just not very pretty to look at.
