@David @MadReefer Can i ask what lights you are using? What is the status of the Dinos?

I have reefbreeder photon v2. Thanksfor asking. My Dino problem has improved dramatically lately. Rock and sand look pretty clean. Coral are still looking pretty mediocre. I have put the lights back to manufactures recommended acclimation settings today. I have to work on getting better coral results now.
Now you have me concerned. Skipping the fuge as I cannot deal with this happening a 3rd time.
I’m happy with the bio pellet reactor. It got my nitrates down to 3. My phosphates went up though. I’m using phosguard in a media bag & a filter cup. I’m starting out slow, with about 1/2 the recommended amount. I’ll measure my phosphates in a couple days. The phosguard works too fast if used in full amount from past experience. Can cause a shock due to rapid change. Also have to test often. When it expires, the levels shoot back up fast. Once I establish trend data, I’ll know how often to change it. Dyno or algae is not an issue right now .
There is no guarantee that it will cause it for you. I just know it caused it for me. My dinos always come back when my aquarium tests 0 nitrates (after adding chaeto - as diana said, dinos love chaeto).
My reef sits at 5 ppm nitrate without a fuge. From everything I have read, and my experience, there are a heck of a lot of different types of dinos. With that said, I KNOW the dinos I have out compete at low nutrient levels. That's why I suggested that concern to you. I don't know your parameters, but if they are 10 ppm or below, I would draw the same conclusion.
All that being said, I used to run a 120 gallon reef at significantly higher nitrate (20 ppm). So I ask the same question someone asked me. If you are stable in your nitrates over the course of a couple months, "Why fix what isn't broken."
given that your nitrates are steady at 0.25 (and you are not having any algae blooms), I would not see any point in adding a refugium unless you wanted more bio fauna. 0.25 ppm is a perfect nitrate reading.
If you are having an algae bloom, the 0.25 ppm may not be a true number as the nitrates and phosphates are being used up by the algae, and those algaes are out competing your dinos (which is why people suggest raising nitrates to try and knock out dinos)
@David @MadReefer How is the Dino?
Looking very good. I am not having any algae problems at the moment.
My calcium keeps dropping to 360. I bring it back up to 410 over the course of a few days, and it goes to 360 again in 4-5 days. My alkalinity never depletes though. I am under the impression that calcium and alk, should be consumed/dosed at similar rates. I am going to stop dosing calcium for a bit and see what happens. I might actually have calcium levels to high, and it reading low due to precipitation.
