1. NEW REPRINTED AND IMPROVED VERSION "The Perfect Pond Recipe Book" Unique DIY Book and Manual by Peter J May ...
I am pleased to provide this space for Peter who has helped myself and my readers so much over the years. I fully endorse this book. I first got it around 1995.
Do any of these questions or statements ring a bell with you?
Have you ever contemplated building your own pond or water garden?
Were you scared off by the complexities of designing and then costing and then actually doing the work of building that water feature in your garden in order to increase the value of your property or just get more pleasure out of it?
Were you afraid it would become a nightmare rather than a dream?
Did this prevent you creating that dream pond your family and yourself always wanted?
I am afraid the water will go green and smelly ... will it?
How many plants must I put into the pond?
How can I put a pond in my garden ... my garden is not flat or level?
Should I use a flexible liner or a preformed pond?
Is it possible to use a liner and create my own stream or waterfall?
How many fish can I put into the pond?
Can I create a wildlife pond?
Just remember this .....
"To have the sight and sound of water near them in a garden has been an almost instinctive urge to people of all cultures in all ages. Now as then, the beauty of reflection, the relaxing sound of moving water and the life that it attracts make the water garden as desirable to many people as a lawn or patio." Peter J May AND ....
Don't worry because you were right to have these fears and feelings ... a pond is an important investment in money and time and you must get it right. All these fears are answered and allayed in my book. This is a book to be used ... it is not for the coffee table. It contains all my hard earned experience over many years actually putting ponds into water gardens ... all shapes, sizes and in all sorts of challenging environments My book does not contain boring descriptions ... you will see how everything goes together. All the tools required for each stage are explained and as it happens; the things NOT to forget are covered, the real time-tested tricks of the trade, estimating and budgeting tips are covered too.
Building a pond can be simple and a great pleasure especially when the pond idea was yours in the first place; especially when you designed the location, the shape, organized the bill of materials, bought the right equipment and conceived the intricacies of waterfall flow and design too. Let my unique extremely practical DIY manual and book help you get it right first time too .....
I am Peter May. I am an author, horticultural journalist and garden photographer. My specialist field is water gardening, about which I have written five books, two of them were called The Perfect Pond Detective. Not only that though, for 17 years I owned a landscaping company that specialised in the construction of water gardens and we built hundreds and maintained many of them for years. Now, I write regular monthly features for two specialist water garden magazines and have covered aspects of water gardening for most of the garden magazines on the British newsagent racks. I also answer any queries of a water garden and horticultural nature for a specialist Koi carp magazine. I have built award-winning gardens at The Chelsea Flower Show, I have created water gardens for Time/Life Horticultural Library as well as instruction videos for Television.
In 1994 the first edition of my book "The Perfect Pond Recipe Book" was published and quickly gained a well earned reputation. Many thousands of this low cost practical book have been sold through bookstores all over the world. It became out of print. It stills remain an unique book.
"The Perfect Pond Recipe Book" was written by me and I also drew the many detailed landscaping picture ideas and practical in-situ sketches that characterized the uniqueness of the book. The book was created when I was a professional landscaper in order to be able to show my clients how complex some water garden situations were and this was a reason why so many projects done by the DIY enthusiast went wrong. Well as the result of many many requests I have now completely updated the original successful version. You will find "The Perfect Pond Recipe Book" ...
"The Perfect Pond Recipe Book" empowers, informs and enables even the maladroit novice on the necessary processes involved in creating a water garden. It doesn't confuse the reader with fancy outmoded techniques like puddling nor does it underrate the skills required for concreting; instead it describes the simple landscapers' techniques for using the products that are available for you to buy like preformed ponds, and flexible liners.
"The Perfect Pond Recipe Book" is not just for those flat perfect bowling green situations. The techniques shown in my book enable you to put a pond or waterfall into any terrain.

Information on Alfagrog
Without getting too technical this means that 1 litre of Alfagrog can hold the
same amount of bacteria as 200 litres of plastic tubes. In other words a box
using plastic tubes needs to be 200 times bigger in volume than one containing
Alfagrog to get the same biological performance.
Alfagrog looks a bit like cinders, it is lightweight, comes in different sizes and you can literally blow through it because it is so porous.

3. Ozone Use In Ponds by William Kelly
Ozone in Koi ponds. It's fairly new but it does work. Before I forget, please visit www.happykoi.co.za for details on our next lecture! Sat 17 July lunchtime, good food, good discourse and good sensible advice and discussion on filtration and filter systems. Please book online be sending me an e-mail - no booking taken at the door!
I had an interesting conversation with a Koi keeper/developer of products with regard to the use of ozone in Koi ponds.
Ozone is a most wonderful substance, provided you're not a really small living organism. It is the second strongest oxidising agent known. This means in a nutshell that ozone rushes around like a mad thing, finds something it can attach itself so and oxidises it. By oxidise I mean react with, but in a specific fashion. Ozone can thus be used to supplement existing filter systems in Koi ponds to varying effect.
This is great news. Ozone thus has the potential to wipe out any free floating algae, viruses, pathogens, free swimming bacteria and so forth, reducing itself to beneficial dissolved oxygen in the process! Is this too good to be true?
Well, yes and no. Yes, if you run too much ozone in the pond, so much that it starts getting into your biofilter before being completely broken down - under these circumstances I would think that most of your Koi would already be dead (oxidised!). No, if you run it in appropriate quantities. This is yet another reason why it is important to know exactly your Koi pond volume...
Too little ozone won't do any harm. It just won't do much good either. As with all things there is a balance. To all intents and purposes Ozone is measured in milliVolts - the more ozone there is, the higher the mV reading. The table below serves as an illustration. I sourced it from
http://www.ozoneapplications.com
0-150 mV ... No practical use
150-250 mV ... Aquaculture
250-350 mV ... Cooling Towers
400-475 mV ... Swimming pools
450-600 mV ... Hot Tubs
600 mV ... Water Disinfection *
800 mV ... Water Sterilization
In water, ozone's half life is remarkably short - from the same site:
Dissolved in Water (pH 7) Temp (C) half-life is
15 degrees ... 30-minutes
20 degrees ... 20-minutes
25 degrees ... 15-minutes
30 degrees ... 12-minutes
35 degrees ... 8-minutes
A half life is the time taken for the concentration to halve. So at 15C, the concentration of ozone after one hour is a quarter of what it was at the start.
I recently installed an ozoniser into my little plunge swimming pool. I have been battling with black algae in the thing since last summer as it stands all day every day in the full sun (nice and warm but forget one cup of chlorine once and you're swamped with algae almost overnight so fast does it grow). I have noticed that the pool water is crystal clear, I don't need nearly as much chlorine and my algae growth seems contained if not actually reduced. But it's still early days and we will have to see how it goes. In principle however, so far so good!
Now, will I be adding an ozoniser to my Koi pond?
I think I will most certainly consider it. It will have to be installed after the bio filter stage, as a final stage of my koi pond filter system (if I put it as the first stage after my bottom drains I would wreak havoc with my biofilters). The appropriate sized ozoniser will have to be considered to develop an ORP level of approximately 250 mV.
More on this to follow. I think the topic is important enough and that ozone can help play a significant role in maintaining koi pond water quality - it has after all been used in major aquariums for well over 15 years already.
