Ich - possibly the most annoying detractor to saltwater fish hobby.

GET A UV FILTER!

It is a must.

I have run without Ich or UV for 20 years now. UV is fine for fish only systems, but in a reef it nukes everything in the water. They are also difficult to maintain. Proper environment and good feeding habits along with QT will reduce your risks of Ich.

I disagree that it is a must. UV's do not get everything. Ich is more either on/in the fish, or dropping off into sand/rock. UV can't kill what does not pass through it and in the case of Ich, that is a relatively small amount.

They also need proper water flow, changing bulbs on schedule and cleaning, etc. I had one years ago and sold it. Helped with algae a little, but still got stuff like Ich (back in my non-QT days).

Proper diet and pristine water goes a long way, but it only takes adding a fish with something like MV to wipe out a tank in a matter of days. Everyone tends to focus on Ich, but there are nastier things out there.

Actually ich is a parasite with a30-60 day gestation period that when hatched gets into the water column and attaches to the fish. The UV filter causes the parasite to mutate and fail to reproduce which means your tank after some time will no longer be a breeding ground for ich due to the mutations.

You are right the fish today with ich need treatment, i meant ( and didn't say it correctly) that everyone should have a UV filter on the system to mitigate ic return and minimize the breakout when a new arrival brings it into the tank

It still only gets what is in the water column and passes through it. It does not all go through the life cycle at the same time, so even with a UV, there is a good chance that some will survive. I'm not opposed to UV, I just don't think that they provide nearly as much as the manufacturers/LFS say they do.

Point taken and i do not disagree. My experience has been excellent since i installed a UV filter with fish even from petco

Nobody is putting them down, public aquariums use them all the time. They are high maintenance and a bit tweety to get the flow/irradiation time right. I try to stay natural and let the water bear whatever is circulating, bacteria, spores and other tidbits that corals filter out. In my system, I am wall to wall coral which I believe is a natural filtration system for organisms, perhaps even Ich.

I'm trying hard to not always go tang police. Yes, the sailfin is not a good candidate but nobody wants to hear that anymore and as long as he's small its no issue. I'm tired of fighting about tangs. The tank size will probably stunt his eventual full size, but that's not for a while yet.
