    Fluval pump u4

    Bought the u4 for our turtle tank. Very quiet and powerful, much better than my previous cheaper pumps. Works great horizontally and arrived in good time.

    I had a u2 in a100 litre tank and it was good, just not enough power. This fits perfectly in the tank and I’m very pleased with it.

    Fluval Filter

    I have been keeping fish since the 70's. A few times the filter needed changing and then I found Fluval. These filters are faultless - take my word from experience. I have just bought a new Fluval which outclasses the rest. Easy to maintain and keep clean, and they are not as noisier as the rest. I look forward to years of satisfactory use so keep up the good work Fluval.

    Awesome

    I did think that it was too big & should have got the next size down but it’s doing great. Help with my green water problem
