    The Journey of Pond Gone Wrong to Something Wonderful!

    This ponds transformation began the first week of September and we are on track to completing it by Christmas this year.  One of our newest members, Aurora, hired a professional Bay Area pond builder, just last year.  She spent a small fortune.  This builder, executed her pond in 3 days.

    We will start with tearing this pond apart and through this blog you will have a chance to learn techniques and equations to creating a pond from scratch.  Here we go.....

    OK, so here is a terrific example of a Pond Gone Wrong.  I will spend some time pointing out poor choices that this builder made in his delivering a properly working ecosystem.  The above view is from Auroras bedroom window and it is the only thing I can say that this builder did correctly.  It is always nice to place the pond in a position that it can be viewed from many different angles.

    From this angle, you can see that the large square (bottom center) is a plastic lid to a skimmer that is best equipped for a swimming pool.  Its placement is also incorrect, the return water coming from the waterfall traveled directly into the skimmer.  There was no bottom drain.  Without a bottom drain, silt and fish waste accumulates and turns into a pea green, mucky mud.  Also, the liner is showing.

    This was the view from across the yard.  It is simply too small for the yard.  It looks like a pile of rocks.  It is difficult to even see the two show pieces of the yard, which for Aurora are those grey bird baths.  One of the problems with the placement of the bird baths is that they are placed too high here, at 3' and 3.5' feet in the air, when the wind blows, so did the water from the pond.  The builder, must have tore the liner when he was filling up the pond with gravel and lining the sides with boulders, her water level was really low.

    Do to the low water, Aurora had to rig a net and stakes, to keep raccoon from eating her fish.  Difficult to appreciate a pond when it is covered up in a netted wad.  A properly built pond doesn't need these type of precaution.  There is no organic use of the rocks.  The water fall was placed in such a way as to need plastic ramps to try to direct the return line to flow into the pond.

    Here, you can compare the over-sized skimmer to the size of the pond.  Although, the soil here is clay based and is really hard, one would not be able to fill this pond up because the top rim is not level.  We haven't gotten rain in years, but if we were to get regular rain again, the top rim can sink or slope.

    Here is another example of how a professional might rig your setup and it is not legal.  I am referring to the grey junction box you see there and the grey conduit.  Several things, are wrong here.  First, is that the power line was laid underneath the waterfall and directly under the sprinkler layout..  Second, the power supply was buried only 8" below the grade level of the yard, it should be 18" below ground. Third, is was tied into the house by being hot wired under the house onto another wire which tripped the bathroom circuit.

    One shot that shows how having the electrical line buried real shallow and directly under the water fall was incorrect.

    This picture shows the bowels of what we now have to work with.  Let the planning begin.  We did some digging here and made the choice to make the main body of the pond to be 4' x 9' x 3.5 deep and it will have a bog off to the side.  In a few more blogs we will start working with math to find out how much the above equation of dimensions = how many gallons this pond will hold.  Since this yard and hole has no actual point of level, we begin with a level line and some orange string to create the ground zero point that every other point of the pond is based upon.

    Here is a sketch of what I propose to create:

    Tune in later for Part 2.

    How to maintain your water garden in the Autumn

    Clear water, a view to the bottom of the pond, clearly visible fish, muscles and crustaceans, all surrounded by wonderful plants at the edge of the pond - this is what makes a water garden really fun. If only the old exasperating issue of algae didn't exist! If you look closely, you may suddenly no longer find it surprising to learn that those very garden beauties around the edge of the pond are, in fact, the death knell for water quality.

    This becomes particularly clear in autumn: Leaves fall from the trees or are driven towards the water by the wind, and bush leaves and branches, once bent elegantly over the surface of the water, begin to die off and fall into the pond. All too often the autumn rains wash soil and mulch into garden ponds. If you don't do anything about it now, all kinds of garden waste will find its way - albeit naturally - into your water garden during autumn. With fatal consequences. Anything that decays in the water now is twice as dangerous. For one thing, the decay of garden waste in water produces fermentation gases which, once dissolved, can endanger fish if gas exchange from and within the water is not possible.  The decayed remains of plants also release their nutrient loads into the pond water, a malicious inheritance indeed. These nutrients feed the algae in the coming year. 

    The most important rule of water gardens is therefore to prevent plants and nutrients from entering the water. To do so, spread a leaf net over ponds and streams to capture larger items. Trim back the plants at the edge of the pond so that no decaying leaves can fall into the water. Extendable shears are useful for this, since you can cut plants which are further away from the bank comfortably without getting your feet wet. Pond grippers with their long handles can also be used now to find and remove plants which have fallen into the pond. Hollow stems on bushes and grasses can be left on the plant unless there is a risk that they could fall into the water due to winds or snowfall. Garden insects like to spend the winter in them. Only cut these stalks in mid/late March and store them somewhere in your garden until the end of April so that the insects can leave them again. The remaining stalks still look beautiful throughout the autumn and winter when they are over-ripe, especially if they are illuminated during these dark seasons with effect lighting (garden lights). 

    Pumping out the sediment or duff from the pond with a mud pump has little effect at present. Fish and natural pond dwellers like to spend the winter holed up in the mud, so save the muck

    Here are a few simple charts regarding feeding and water temperature. When your water gets really warm, I suggest cutting back on a food on the hottest day and lots of aeration.  Remember, warm water is close to hot water and hot water is close to boiling.  Aeration assists in cooling the water.

    Water temperature can dictate how and when you feed your fish. Careful consideration should be given to the condition of the environment as well as the activity level of your pets. Also consider your own knowledge and experience with your fish!

    Koi are most active in this temperature range. You can feed as often as you like any of our color enhancing, growth or staple diets. Feeding smaller amounts more often can actually increase weight and girth more rapidly. Always monitor your water quality and the activity level when deciding how much to feed. Always avoid feeding within one hour of sunrise or sunset.

    Carefully monitor your pets activity level in this temperature range. As the water temperature drops so does your koi's digestive capacity. Care should be taken to avoid over-feeding and offering food during periods of inactivity. Always feed during the warmest part of the day if your water temperature is not stable.

    When your water temperature is in this range you should monitor your koi's activity level carefully and avoid feeding if you pets do not readily eat. Use only easily digested diets like Hikari Wheat Germ. Try to feed between 10:00 am and 2:00 pm if possible.

    When the water temperature is in this range, technically you may stop feeding until spring. If your koi are active and you want you can feed an amount they will consume within a minute or so, but never more. Always try to feed between 10:00 am and 2:00 pm.i

    Your koi should be in their hibernation mode now and no feeding is necessary.

    Our Mtg. in September was at the esteemed home of Grant Fujita.  What an eye opening experience and a realization that 99% of us are actually ornamental koi fish pond keepers, and there is nothing wrong with that.  Grant is that 1%.  I have seen it with my own eyes.  Grant is a true Nishikigoi (Koi Keeper).  How do I round up the information and education we gained from this meeting?  Grant has raised a $50,000. Koi, that is the size of a small seal, pristine confirmation, crisp white and painted red.  Stunning!

    Thanks to Don Chamberlain we have this shot for you:

    Great get together of old members and some visitors that are now new members and we welcome you all.  We had the opportunity to shake hands with our sister club, the Santa Clara Valley Koi & Water Club and look forward to future mingling.

    Heads up to anyone looking for fish for your pond, we have a couple recent posts in the Forum about Rescue and Adooption.

    In a nutshell...we had a great couple hours mingling and catching up.  The koi pond  at the Hayward Japanese Gardens certainly needs some work.  Maybe at another time we could revisit how we could help make it better.
