Interesting. I have amphidinium and am wondering if I wasted the money on the UV...
I have read a few thinks where adding live phyto from Algeabarn (Marinemajik) will help out compete the dinos. Not sure. I ordered some and than started thinking well dang my new UV is just going to kill it all...
Yes, if you have amphidinium, UV won’t help. I still run my UV because we often have mutiple species.
If I were you, I would:
1. Remove any nutrient removing things like carbon dosing, nopox, siporax, blocks or bricks, chaeto fuge, etc. I would do weekly wc, and keep your alk/ ca maintenance method.
2. Run GAC to remove dino toxins.
3. Dose nitrates to about 10 ppm and phosphates to about 0.1 ppm to encourage other algae growth. Don’t worry too much about the numbers, but make sure you have measurable quantities.
4. Add biodiversity with piece of liverock or rubble.
5. Dose silicates to encourage diatoms.
6. Manage algae with physical removal and cuc. Add more cuc when the tank gets really ugly.
7. Once cuc is established, stop dosing and allow nutrients to come back to a natural level. This will be months down the road.
8. Consider removing sand if all else fails. Some amphidinium reefers believe this helps most.
