Thanks for the reminder!
I haven't been very active lately, but the tank is doing well. Here are some pics I took today:
My neon green caulastrea grew to a pretty nice colony. I bought it as one of my first corals with only 2 heads, now it has around 20! Since it was doing so well I also bought a bicolor and mint caulastrea. Such cool corals

I also added a few rhodactis and acans which are all doing good.
Like I mentioned earlier I basically stopped doing waterchanges since september. I dose alle for reef and have a refugium to keep all parameters in check. One time I had a bit of cyano coming up in the tank. I did a waterchange to syphon it out and turned down my refugium for a while. I also did a korallen-zucht cyano treatment. Luckily everything stabilized in a few weeks.
For a while I'm having a bit of struggles with vermetid snails. I figured it was time to take some action to get the vermetids under control. I had a massive smash vermetid session to kill as many as I could. After that I used coral snow since people seem to have good experience with it. Didn't really notice much difference so I stopped using it. I got a new yellow wrasse (one of my favorite fish), hoping it can help control the vermetids. My previous one ate all of them, but of course this one doesn't at all haha! But since yellow wrasses are so pretty, I don't mind it. Some people say bumble bee snails also eat vermetids, but they are super hard to find in The Netherlands, so I ordered some from Germany. The bumble bee snails are often around vermetids, but I have no evidence they actually eat them. But it's been over a month, and everything seems to be under control.
Since everything is doing well for such a long time, I wanted to try SPS again. So yesterday I got a small red montipora frag (upper right corner in the second photo) and a small motipora undata frag. I have a bad track record with SPS tbh, but it's been a long time so let's hope I will do better this time.
