Hey everyone! 👋 I’ve been meaning to start this thread for quite a while, and I’m finally getting around to it. I’ve been reefing for about 4 years, and it’s been quite a ride — full of learning, upgrades, and plenty of coral growth (and the occasional setback 😅). BackgroundI started with a small nano tank, which taught me the basics of reef keeping and gave me the confidence to scale up. Over time, I upgraded to my current system, a Red Sea Reefer 425 XL, which has been running strong for the past couple of years. My tank is SPS-dominated, so stability and flow have always been top priorities. Recently, I decided it’s time to take things to the next level. The Next ChapterThe new setup will be a Blau Super Reef 122, which is currently on order and should arrive in the coming weeks. I’ll try to document the entire process here — unboxing, plumbing, aquascaping, cycling etc To prepare for the upgrade, I’ve already sold off some of my larger SPS colonies to make the move easier (and to give the new system a cleaner start). Current System & EquipmentDisplay: Red Sea Reefer 425 XL Lighting: 3x Radion XR30 Gen 5 Pro Flow: 2x Maxspect Gyres + 2x Jebao DMP 30 – strong, alternating flow patterns Filtration: ClariSea Gen 2 SK3000 Refugium: Small refugium box for nutrient control Calcium/Alk: Deltec Calcium Reactor – consistent stability for SPS growth Water Changes: Apex DOS for automatic water changes Monitoring: Apex A3 Controller + Apex Trident UV Sterilizer: Really excited to starting new tank soon. I am adding some of the sps colonies which are sold but I have smaller frags for new start.

I had it for 1.5 years and recently upgraded to red sea 425. These are new coral frags which were doing quite good since few months but suddenly they started to turn white. I have done 40% water change this week and removed the parts which were turning white and treating the tank with Fauna Marin RTN/STN X for Tissue Nicrosis. I can see good results from last two days. I hope it continues but I still don't know what was wrong.

Hello reefers.My corals mainly SPS are being impacted by something which I cannot identify. They are turning white and I am not able to control it. Any ideas?Kh : 9.2 (+-20)Ca : 480Mg : 1338PH : 8.04-8.27ORP : 235Temp : 25.8-26.1 celciusNo3 : 20 ppm approx
