Conversely, wildlife ponds should be fishless, and far shallower. Maximum depth of 12” is fine for a wildlife pond, with wide, shallow areas for wildlife to climb in and out easily. According to wildlife and wetland experts, the shallow areas of a wildlife pond, just a few inches deep is where the most life exists.
I decided that for this pond I wanted fish over swan mussels so had to empty out the green soup pond water and replace it with clear tap water. My plan is to introduce a nature pond in the back garden at a later date and put swan mussels in there and not introduce fish or a filter to that environment. A natural pond would attract frogs to spawn and newts to take up residence and be another great environment for Océa to learn from but for this first pond I wanted fish and clear water. I filled it up with water from the hose pipe and left it to sit for a few days.
In the evening I fished Pond ‘1’ to check on the condition of the fish before adding more, half-expecting the fish to be slow to the bait after the morning feed. Surprisingly, though, I began catching straight away and had about a dozen fish before deciding that I’d found out all that I needed to know. All but one were 5″ crucians, all in excellent condition, plump enough to suggest that they were making the most of the trout pellets.
The flush-away hose is just 45cm long and as it is positioned above the surrounding area I can easily flush away dirty water and debris into a bucket before disposing onto my shrub borders. The Booster itself should be sited on a flat level surface which can be above or below the pond water level. The 4 hoses can then be connected; these should be of the same diameter, personally, I would suggest either 32mm or 40mm so that the required volume of water is transferred with ease. On installation, there are a number of basic rules to follow if trouble free operation is to be achieved. Firstly a flow rate of between 3000 and 8000 litres per hour is needed, so ensure your pump will deliver this requirement. The Booster must be positioned first in the filtration cycle, directly after the pump, and before the UVC and biological filter.
Unfortunately underfeeding seems to have become a means of managing water quality in tanks which are too small for the species being kept. Many keepers don’t realise that this is what they are doing. They take advice not to overfeed and follow this advice carefully. However, due to inexperience they don’t appreciate the bigger picture and often don’t realise their fish are suffering from malnutrition. Goldfish, for example, eat a huge amount of food and are naturally very large fish. It would not be possible to keep a goldfish in a small tank and feed it the right amount without experiencing poor water quality.
Dont cut the boiler or pond pipe work until the rest of the heat exchanger plumbing is finished and you are sure that you have the correct fittings to complete the job. A small heat pump can cost less than £500 and will use typically in the region of 1kW of electricity, whilst it is running. The output is rated in terms of COP which is a measure of how many times more efficient it is than an electric heater of the same rating. For example, a heat pump with a COP of 6 will produce an output equivalent to a 6kW electric heater for each 1kW of electricity it uses. Small ones typically have a COP rating of between 4 and 6 when the air is warm.
At this juncture I would stress that this is a pond which houses Koi, it is not a purpose built Koi pond which has bottom drains, skimmers Vortex’s and thousands of pounds worth of equipment as is the case with serious Koi enthusiasts. We have a number of Koi in this pond which we inherited with the house and these too have prospered whilst in our care. Even now I would like to enhance the filtration further but, as always, time and money are my eternal enemies.
Anyone who hopes to catch on Sunday will have to know his business – so there’s a challenge. The Canadian pondweed dominates ‘1’, and even the one swim that I cleared and that I am feeding seems to be getting smaller. A fly or tiny floating lure might take the chub, above the weed. There are plenty of fish in this pond as we know from the netting, but who can catch one or two, I wonder.
