Grosvenor Tropicals fully endorsees the OATA's policy on the humane  treatment of livestock. We may refuse any sale where we believe that a customer cannot provide a suitable environment for care of that species.

No longer the preserve of the fanatic, or the rich bloke with the PhD, Marine Fishkeeping is now more accessible than ever and one of the fastest growing sections of the hobby. Some newcomers are even bypassing Tropical fish keeping altogether and starting off with one of the many 'Complete Setups' which are available.

With the right information, a little guidance, and the help of modern equipment, this is not as risky as it once was. Modern techniques combined with a greater understanding of marine ecology make it a much more satisfying proposition, for the fish keeper and the fish alike.

However, I don't want to over simplify the whole situation. Marine fish keeping is more complex that 'Tropical' and does require more work, and "Study", to make it a success. Water quality is of paramount importance, and it helps a lot if you take the time to understand what this means. I don't mean studying for degree in chemistry, just general knowledge of what the various test kits are trying to tell you.

There is also some extra equipment which might be unfamiliar to a tropical fish keeper, Protein Skimmers, Fluidised Reactors and Hydrometers to mention a few, but nothing that can't be explained in fairly simple terns.

So, if your thinking of taking the plunge into Marine, or have already done it, this is the section for you. As with the rest of our web site, it's not meant to be a sales catalogue, more of an information source and we hope you find it helpful.
