Editorial: August 2006

Terry discusses reader email.

Received by email a few days ago:

In case there was any doubt about the success of lionfish in the Atlantic, we did our first dive of the year on the Ponquogue bridge Thursday and within 20 minutes, my buddy and I had caught 11 juvenile lionfish. Another diver had 18 of them in a bucket and several other divers were commenting that they were seeing them everywhere.

Well, it looks like lionfish are here to stay in the Atlantic, and what kind of ecological problem they will cause has yet to be determined.

I received the following exchange from a aquarist in Germany regarding my last editorial where I explained the devastating lose of my fish to a parasite.

Dear Terry Siegel,

I'm responding to the online statement regarding the parasite problem that you had. I experienced the same disaster. I lost most of my coral fish a few years ago, angle fish, butterfly and others. I then bought a group of new butterfly fish. A few days later an infection of Oodinium appeared in the tank and all fish were ill. My old 16W UVC at the 1000-liter tank was too small, but I thought at first that the lamp was powerful enough. Together with the trouble of my new fighting fish I was confronted with a big problem. I put the sea anemones and corals in another holding tank, then I used copper and killed the complete biological system. 50% of the fish died. I wrote an article about that in a German magazine. We moved into a new town and the same problem came again. So this time I used no copper. The solution was the installation of 50 watts UVC per 1000-liter aquarium water. So after 2 years of experience I can say that parasites are not more a problem. I change the UV bulb each half year. If you want I can translate these articles for you. We spoke about some articles that I can write for your magazine.

Kind regards, AquaLogistik

I replied:

I would love a translation, and thank you for your advice, and did you ever try ozone, O3.

He replied:

Yes I tested O3. But it was not effective enough. I used a large protein skimmer with max. 50mg/1000-liter tank volume. UVC is much more efficient and safe for humans and your fish too. You can install a large lamp in an infected system. After 3 - 4 days you will see the results. Problem is that most people install only a very small lamp in their tanks.

We installed big UVC units at several import and export stations for marine fish here in Germany, Kenya and Singapore. Use 50 watts for 1000-liter volume, tank circulation minimum of 1 time per hour passing the lamp. Then you can forget the problems with Oodinium or Cryptocaryon and other germs.

I replied:

One of the problems is that my system is 700-gallons; I would need a lot of UVC, and the bulbs would have to be cleaned often and changed regularly.

To which he replied:

700 Gallons are approx 2,500-liters. Than you need altogether approx 165 watts, which means 3 lamps, each 55W. I clean the bulbs when changing the lamps only 2 times per year. The lights are very cheap here in Germany (T8). For more details you can ask the company Tropical Marin cented in the UK. They produce the lamps for us. They use it in their own import station and they can produce lamps for special applications.

If you want more details pleas ask for James Hayes and let him know that I gave you the contact. They can help you with a contact in the USA. I know that Aquatic Eco system in Tampa/Florida sells the UVC for them.

My new fish are doing well, with the juveniles growing extremely fast, partially because I feed them several times/day. And, I always have a sheet of Nori hanging in the tank, which as you can see from the pictures is grazed on constantly.
