Advantages: All in one solution. Neat and tidy. Disadvantages: Needs setting up prior to installation.
model, designed to get the algae to group together so that they either settle to the bottom of your pond instead of being in suspension. Alternatively, the filter in the FishMate gets clogged with the blighters and you have to clean them off periodically. The water overflows from the first chamber into the second chamber where the filtration is. There are two sponge elements, one for coarse and one for fine sifting. Once through these, the water goes through a biological filter. This consists of special rocks that have a massive surface area in relation to their size. Bacteria naturally breed here and clean your water further. You need to rinse these rocks in a couple of buckets of pond water prior to installation. Don't use tap water as the chlorine does not make a good environment for the bacteria - quite the opposite in fact ...

As my pump was getting old and was really too small for the pond, I decided to buy a new one. Having already installed a Fish Mate UV+BioFilter a year ago, which I have been very pleased with, I opted to purchase a pump of the same type. I chose the 4000 which has a maximum flow of 835 gallons an hour, has an anti-clog filter design, has superior wear resistance and reported to have low running costs. It also has a fountain set with four options.
As soon as I received the pump I set to to install it. It was very easy to do, but I did make the mistake of not checking the size of hose required when I purchased it and discovered that mine was too small. I was cross with myself as I wanted to get it set up that day, so I would advise anyone buying this particular model that they make sure they have a 1" or 1.1/4" bore ...
