UV recommendations

[pillar coral]

I've been out of the hobby for a long while and have been wondering why I can't find any UV posts. I am aware of the POD issues with using a UV and would like to know if anyone has any recommendations. my tank will be a 90 gallon with fish, inverts, and corals. Thanks

There are a lot of threads about UV. Did you use a search engine?

What size UV Sterilizer Should I get?

UV Sterilizers are created in many different sizes from 8 watts to 240 watt for the aquarist, and even higher wattages for larger applications. What wattage to go with is decided by the size of the aquarium you plan to use it on. The unofficial rule of thumb in determining the wattage is 10 watts per 75 gallons water volume for saltwater application and 10 watts for every 150 gallons for freshwater closed systems. In pond application this is greatly increased to 10 watts per 1000 gallons, due to the suns natural capability of producing UV rays. It never hurts to get the next size up from the minimum to allow for bio-load, particles, and turbidity of the water. These factors affect the efficacy of the unit.

With SunSun branded sterilizers being so inexpensive these days, I don't see much point in not getting the larger units. The bulbs they use I would not consider to be the best as far as output, but they at least use true UV bulbs and not those made for nail paint curing. They are standard sized bulbs, so you can swap them out with whichever brand you prefer. 36w units are $70, and 55w units are $90 on Amazon.
