The audio isnt your normal standard, at least not on my headset. And i am inclined to agree on going for an achilles indeed

Thank you for this. i am still hesitating between a sohal and an achilles tang for my 300/90/80 fowlr and after seeing this vid, leaning more towards the achilles :) btw, maybe you can fix the audio on this video?

achillies would be a better option I think. What's up with the audio?

Do you still have your mustard Tang? I had one back in the day and he was the meanest fish and crazy even meaner than the clown tand and Sohal

Yes it's still in there seems a very peaceful chap, as the joint first fish in the tank it's seen a lot of changes.

I'm wondering about your use of UV. I also run UV on my 400G with 11 tangs. I think my UV has a similar power rating to yours. Mine is an 80W HO. I don't have ich in my tank. I may have uronema. It's not uncommon for me to turn off my UV for a day or a week. For example, if I was adding any kind of benifical bacteria I would turn off the UV completely. My standard run time has been 12 hours a day. The UV has been on when the lights are on, and off at night. My logic was to control photosynthetic algae in the water column. UV does harm some of the benifical organisms and bacteria that find their way into the water column. Having started with a sterile tank, a lack of bio diversity has been a problem for me. More recently, ive switched to 4 hours of run time per day. On when the lights are at peak brightness. There is speculation that UV can unbalance the bacterial mix in our tanks. Harming some of the benifical bacteria and making room for potentially harmful bacteria. This concept, while perhaps speculative, has been linked to HLLE/HLLS. Non of my tangs show any sign of this, but I do have a wrasse (oddly) that has early stage symptoms. So, I guess my question is... What is your approach to UV and why? I'm using it primarily for water clarity atm. It is plumbed on the exit side of my skimmer loop. In future, when I get my ozone back online, it's primary purpose will be to break down the h2o2 coming out of the skimmer. I intend to limit the use of ozone/uv to an hour or two daily. For most people, who likely have ich in their tanks, I would recommend running a big uv 24/7. For those of us with strict qt protocols, uv serves a different purpose. Just wondering what your philosophy is here.

So I run 160w of UV 2 x 80w. I run at 2500l an hour so just under the tank volume per hour. I run mine only for parasites really, I don't think I have ich in my tank but I use the UV just as a precaution really. I run mine 24/7 but I also carbon dose so I'm not that worried about lack of bacteria. I think keeping the UV on constantly maintains a level of bacteria a bit better than fluctuating by turning it on and off. I also wonder if the quartz sleeve gets a covering if the bulb isn't on and reduces the efficacy when it goes back on.
