Drought Restrictions and your Pond

Since June 2011, drought has affected Lincolnshire, Cambridgeshire, parts of Bedfordshire and Northamptonshire, and west Norfolk. In February 2012 following a dry winter, Hampshire, West Sussex, East Sussex, Kent, Surrey, London, Berkshire, Hertfordshire, Buckinghamshire, Oxfordshire, the east of Gloucestershire and the remainder of East Anglia are now in drought.

Water companies that are facing an increased risk of drought are taking actions to co-ordinate temporary restrictions on water use, such as hosepipe bans. Many have been taking to the Environment Agency about drought permits as early as possible.

On 12 March 2012, seven water companies (Anglian Water, South East Water, Southern Water, Sutton and East Surrey Water, Thames Water, Veolia Water Southeast and Veolia Water Central) announced they are consulting on temporary restrictions to be in place by 5 April 2012. For further information on the restrictions see each company’s website.

The Water Use (Temporary Bans) Order 2010 includes:

PART 2 Categories of Use

10. Filling or maintaining a domestic pond using a hose pipe

11. Filling or maintaining a domestic fountain

However, it does not include a “Domestic Pond in which fish or other aquatic animals are being reared or kept in cavity”

In addition, it does not include an “ornamental fountain which is near a fish pond and whose purpose is to supply sufficient Oxygen to the water in order to keep the fish healthy”

According to DEFRA, fish keepers with Ornamental Ponds are permitted under current ‘Drought Legislation’ to maintain essential water supplies to their existing ponds and tanks which hold Aquatic Livestock and maintain fountains and water jets used to provide the essential Oxygen.

However, we suggest that this exemption is applied prudently. Try to save water whenever you can through structured water changes, use of vegetable filters to reduce Nitrates and attend to any leakages sooner rather than later.

Reading the Regulations, empty domestic ponds (without Aquatic livestock) cannot be filled in areas covered by a hosepipe ban.

Cold Weather Advice

During the next few days, temperatures will drop. Looking at the weather forecast, they are due to plummet further over the next few weeks. The experts say that there will be snow in some parts of the UK tomorrow as I write.

For the majority of you with unheated ponds, it may surprise you that the water temperature is about 5 deg.C. at present This is likely to drop further. Now is the time to take a few simple precautions like:

North Denmark – early March 2011 - Waiting for his ‘Full English’
North Denmark
– early March 2011
– Waiting for his ‘Full English’
  1. Stop feeding completely if the water temperature is below 5 deg.C. (feed sparingly from 5 deg.C.- 7deg.C.
  2. If you have a winter protective cover, it should now be on to reduce chilling – the cover will help to prevent heat loss and keep the water 1- 2 deg.C. warmer.
  3. Bypass any waterfalls, turn down the air (but leave some going). Do not stop the filter.
  4. If the pond water surface freezes, melt the ice to form a small hole to let the gases escape. Do not mechanically break the ice as the noise and vibrations can injure your fish.
  5. Drain the garden hose and put it in the garage to make sure it’s kept operational – hoses will freeze and block if left out. You made need to fill the pond in a hurry if you have a burst pipe etc.
  6. Keep a look out for Herons – you are more likely to get problems from predators like Herons during the winter when their natural food source is in short supply. We had our only attack last January.

HealthyKoi - Winter Advice

  1. This is one time in the year that a thermometer is most useful and it need to be part of your kit. Try not to let the pond water drop below 5 deg.C. The Koi will survive at lower temperatures but the risk of losses are far higher. The weaker Koi will go on their sides at about 2 deg.C. and swim bladders can be damaged.
  2. A large aquarium heater which has a low energy consumption will give a little bit of ‘background’ warmth. Our many other heaters will provide more sustainable warmth.

If you have any worries about your pond or the behaviour of the fish, give our team a call on 01243 698284 or 01243 572762.

Have a good winter season

Aquatics Live at London Olympia Exhibition 19th- 20th November, Healthy Koi undertakes water quality management

Fishkeepers are in for a treat this November as a new major aquatics exhibition is taking place in the UK. Based at London’s Olympia, Aquatics Live 2011 is the first of its kind in the UK, combining expert seminars and live demonstrations with major manufacturers and leading British retailers.

Over two days in November, Olympia will play host to the UK’s greatest event for the aquarists and will bring together exhibitors drawn from all over the country, giving visitors a unique chance to shop, ask questions and see first-hand the widest range of available products. They will also have a rare opportunity to talk face-to-face with manufacturers and see demonstrations of the latest innovations in fishkeeping.

In order to ensure the best possible conditions for exhibitors with aquatic livestock displays, Healthy Koi have been commissioned to undertake the water testing for the mains and tank water supplies to both floors in the exhibition halls. The results, together with any recommendations and comments have been issued to the exhibitors to ensure that they undertake any necessary measures required to suit the particular species that they wish to show.

Spring Health Problems & Seasonal Preparations

This year, we have again had a very harsh and severe winter. In some cases, ponds were frozen for a prolonged period and without pond heaters to keep part of the surface free from ice, many Koi suffocated. Others, who have been weakened by the prolonged cold spell will emerge in the spring with depleted strength and not in the best of health. As a result, it is important that their environment is well looked after, they have excellent water quality and you start feeding again with wheatgerm/ multi-season feeds as soon as the temperature allows. Blood samples taken at this time of year often show the Koi to be anemic. The resumption of feeding will help them with any nutritional problems and to regain their former condition.

Some of the fish problems which are occurring at the present time is due to water toxicity. This often occurs when we have had a poor winter and a lot of debris can end up in the pond. A good clean-up and controlled water changes usually cures these problems.

Pond & Environment

Test the water

  • Clean and vacuum the pond.
  • Strip and clean pumps.
  • Check all valves and pipework – now is the time to undertake those changes before the heavier feeding starts and the filtration system builds up efficiency.
  • Re-direct / re-connect waterfalls which have been bypassed during the very cold winter spells.
  • Clean and flush the filters – use pond water and clean alternative biological bays at weekly intervals.
  • Reinstate any reduced air supplies.
  • Replace the UV clarifier tube so its at peak performance when during the summer.
  • Test the water – this is most important when the feeding protocol changes (ie resumed/ increased feeding rate or food type).
  • Remember that it will take time for the biological filter to build-up again.

Your Koi

Bowling up
Sit by the pond, have a cup of tea or coffee and just watch the Koi for a while – they will tell you if there is a problem.

  • Look for any surface blemishes, marks or changes in behavior.
  • If there are any changes, bowl-up and carefully inspect the Koi – invert and look at the underside of the body and the gills.
  • Do not treat the pond as a matter of course.
  • If you think you may have a parasite problem, check with a microscope and mucous scrape first. If it’s confirmed, select the best medication to treat the problem, bearing in mind water temperatures.
  • If you find costia, remember that this is a secondary parasite and is only found on 1 or 2 unwell Koi – look for the cause.
  • Keep an eye on the water temperature and feed accordingly. If temperatures look like dropping again, slow the feeding rate.

If you need any advice or have any concerns, do not hesitate to contact on 01243 698284 or 01243 572762.

New Filtration for Healthy Koi

Healthy Koi are pleased to announce the launch of the Sansai shower filters. The Sansai shower filters are an attractive and economic way to provide extra biological filtration and aeration to your pond.

Sansai Junior Filter

Made from UV resistant high density polyethylene, these filters are less prone to heat loss than metal equivalents. They are available as a small or large model, for 3,000 or 6,000 gallon ponds respectively. Both models have a 50mm inlet and a choice of a weir or 110mm pipe exit. The choice of exit allows you to mount the shower either, beside the pond, with the weir exit, or in your filter area with the 110mm piped exit.

The showers are fed by a pump, preferably after a pre-filter or existing filtration. The water passes through spray bars at the top of the unit, which distributes the water evenly over the filter media. As the water passes through the unit, it will move through the layers of media, splashing and aerating as it descends. At the same time, oxygen is drawn through numerous vent holes, which is used by the bacteria and to aerate the water. After its journey through the unit, the water arrives at the bottom collector unit where it is returned to the pond via a 110mm pipe or weir.

Although these units are available from £395 (Small) and £595 (Large) without media, we would recommend buying the unit with the filter media. Healthy Koi offer the Sansai Small with media for £455 and the Sansai Large with media for £715. The Healthy Koi packages use BioPore filter media, which is an excellent and effective ceramic media. BioPore is extremely porous and lightweight allowing for a larger colony of bacteria and for more biological filtration, than other medias.

For an easy and attractive way to improve your water quality speak to Healthy Koi on 01243 572762 about the range of Sansai shower filters, or go to
