Based on my research, I have two recommendations for you...

1) buy a UV sterilizer that's rated for a tank bigger than your tank
2) look at the recommended gph, and aim for the bottom end of that range for a pump


I have a 9 watt rated for up to 100 gallon tanks on a 42 gallon tank. The recommended flow is 100-200 gph, and I have a 100gph pump running through it with some head pressure, so I'm getting more like 60-70 gph. It seems to do its job quite nicely. The water remains very clear.

I would just like to go one step further with Gauge's comments and explain.

One of the biggest mistakes made with UV units is people will get underpowered units and then force to much water thru them at to fast of a rate. UV sterilizers work by exposing the water and subsequently the creatures in your water to the UV light. Just like with the sun and your skin the UV rays if your exposed to long will burn you. The correct exposure to the UV rays will kill the bactera, parasites, algae spores, etc in your water. The incorrect exposure (to short) will do very little in the way of killing these items.

Unless you get a large UV unit it should be run by its own pump vs beign connected inline with your main filtration pump.

Remember to add the UV bulb to your list of items you must replaced on a set schedule.

It's a CoraLife 9watt turbo twist with a Minijet 404 running at about 6 inches of head pressure.

I have a 90 gallon tank... Can you give me a specific Reccomendation: Make, Wattage, and Pump rating?

I'd go with a 15watt (I believe those are usually rated for 150-175 gal) and the one I looked at recommended 200-300 gph of flow. I'd say, if that is the case, get a rio 600 as your pump.

As far as UV sterilizer brand, I would just go with a brand name of any type. I don't believe there is any real difference between them. It's just a bulb with a compartment for water to travel through around it. I just say name brand so you know you're getting a quality item that won't die on you in a month.

It was suggested that the cloudy eye that is affecting my hippo tang and coral beauty is most likely a result of parasites which the UV would take care of. I hope that advice is correct. It's better to treat the source than mask the problem and stress my fish more... plus, a UV can only be beneficial right? Anyway... I bought a Custom Sealife and a MaxiJet 1200 from Marine Depot ... 120 & 19 (respct.)
