Advantages: Good design Disadvantages: Stickey Valves
I have been trying out the Tusa TR 400 Imperex for two weeks now. I have found it to be very good regulator. The valves seem to be of good quality. At first it worked perfectly and I thought I would never use another regulator. However on my fith dive with the Tusa TR 400 Imperex. As I reached the 40 meter mark the regulator got stuck in the open possition and was squerting out air. When I reached the surface and took the regulator to a reputable dive centre they informed me that the problem was that Tusa had fitted a faulty valve. He fixed the problem and the regulator has been fine since then. I don't think it's a common problem so I wouldn't worry about it.

Advantages: Very little effort required underwater, flexible Disadvantages: Not cheap, not the best for long surface swims
My Mares Volo Power fins are among the favourite items of my dive kit. While pricey, they do a very good job, and make finning underwater incredibly easy. One of the few drawbacks is I find they're not as good for surface swims, particularly against current. They are longer than many standard fins, which takes some getting used to, and it's something to be aware of when you're near fragile coral reef. However, they're also ultra-flexible, and I usually find I can get back into the boat while still wearing them.
Initially I found the quick-release catch at the side to be rather cumbersome - the lock-unlock mechanism isn't very easy with gloves on. To be honest, I've now taken to closing and not locking them, and they've never opened up while I'm in the water.
When these fins first appeared on the market they were pretty expensive ...
Advantages: Healthy food for fish Disadvantages: none
I have had my aquarium and fish now for two years and from the start I have fed them TetraFin Flake food. (This was recommended to me when I bought them). It consists of, as the title suggested, flakes of different sizes and colours.
It is recommended that your should feed your fish two to three times a day, with as much food as they will consume in a few minutes. I have a fairly small aquarium with two medium sized fan tail goldfish and a further four tiny fish and I have always fed them twice a day with a good size pinch of flakes. They have always kept their bright colours and the water stays very clear.
TetraFin is manufactured and sold World-wide by a German company, Tetra GmbH, and has been the World's leading Goldfish food for over 40 years.
"It provides a balanced and nutritious diet for goldfish, ensuring that ...
