I use a filter sock in left chamber, change out every 2-3 days. Nothing in second chamber. I have my heater and return pump in middle chamber. A bubble magnus protein skimmer in fourth chamber, have it off right now since parameters are low. The right chamber holds a IM desktop UV light. I have an AI prime for light, a Nero 3 for flow. Below is a pic, a lot of algae, hate showing it like this but it is what it is. The reward wouldn’t be worth it I guess it is was easy. The struggle is real.
this was about 8 months ago, I had such terribly ugly phases. First algae, then I assume dinos, then the worst cyano outbreak... so bad if I didnt blow off my corals every day they'd smother and die. Time, good upkeep, more cuc, and I threw in some high quality live rock, then it just cleared up on day. Literally within a week, everything changed. Its a process bud, theres no shame in it.
