OUT IN THE GARDEN: Readying the pond for the fish

By Spalding Today Columnist

I’ve been looking forward all week to stage two of my pond rejuvenation.

Last week I added several oxygenation plants and lilies to provide shade for the pond to prevent the build-up of algae.

Now the pond is almost ready for fish to be introduced and I know my little furry four-legged friend Teddy is very excited to see the results.

Though before the fish can be added, I need to ensure that the water can sustain the fish and provide a suitable environment for them.

Now, over the course of the last week, I have been reading up and speaking to those in the know about pond filters, UV lights, and starters to try to gain a better understanding of how it all works.

Teddy has been getting used to his new friends.

I’ll try to condense what I’ve learnt so that it’s easier to understand.

Fish require friendly bacteria to be present in the water, also just as importantly the water needs to be full of oxygen.

This eco system can be created with a little help from modern technology.

The first thing to do is to add a specialist product, such as Tetra Filter Start, which you can purchase from the pet and aquatic department at Baytree.

By adding this product to your pond, it will introduce fish friendly bacteria which will then multiply in the water.

I already have several oxygenating plants in my pond, but in order for my fish to thrive, I’m going to add a pond fountain filter and UV light system.

I’ve opted for a Hozelock EasyClear 9000. This simple-to-use and install product will keep the water moving and well oxygenated.

Correctly filtering the water brings a number of technologies together, namely a filter and a UV light.

The filter filters the water and removes large particles from the pond water.

The UV light is a little more complex. This UV light and filter, which came built into the EasyClear 9000, causes the algae to clump together.

These large clumps of algae are then caught and trapped by the filter system and clean water is allowed to flow back into the pond.

So here we go then, into the pond I submerged the fountain at the advised depth, which I found in the simple instruction leaflet.

I am quite fortunate as I have an outside electrical socket at the rear of my house, which is only a few metres from my pond, so chasing the wires underground from the pond to the socket was not that tricky. I just used a spade to remove a line of soil into which the cables could be buried in a plastic pipe.

Twenty four hours after powering up on my fountain pump I took my five Comets, which are red and white gold fish, and gently lowered them into the pond whilst they were still in their plastic bag.

After 30 minutes or so, the water temperature inside the bag equalised with that of the pond water and it was time to release the beasts.

I felt like I was in Born Free, however, Teddy having never seen fish before thought they were the best thing ever and he spent the next four hours staring at them in the pond, and, with tail wagging, he kept running back and forth to beg me to come over and look at the fish with him.

So far so good!
