The inner side will be lined with black ribbed non reflective tiles, I wonder if smooth, hence reflective tiles won't be nicer.
Anyway, the things need to be cut with a cutting machine and I will have to buy one, renting one is presumably out of the question.
But I am not sure if such a cutting apparatus will be able to cut ribbed tiles or just only smooth tiles.
Anybody knows or has experience ??
Thanks for your input, P.
Make sure you have installed a drain system in the bottom with an outlet pipe.
Construct the pond based on maintnance required. Any tile suface will soon be covered with alge ect. Concrete is used in many of these applications. Actually it is in fact a grout. Concrete contains aggregates of a size that doesnt allow the correct finish to be applied to the top surfaces. Grout is simply sand, cement & water.
The grout must be placed properly to obtain a hard, durable surface. This means it must be placed using as little water as possible yet be workable. There are additives sold to reduce the need for water. These look like dark water & are used in very small amounts. Probably hard to find in Udon but you could buy them from a concrete plant.
If its not feasable to do that just add the water in small amounts as you mix the grout. Have enough material & manpower to do the entire placement in one hour. Once the grout is placed in rough form sprinkle a small amount of water on the surface & begin to seal it with a steel or magnizium trowel. A pool trowel is best. It has rounded corners. Working the surface causes sub surface water to migrate to the upper surfaces. Watch the surface for color & texture. It should appear to be dull not wet as you seal it. Keep the trowel edge slightly up as you work. This produces a hard close grained surface.
Even if you used tile it would have to be set on a grouted surface constructed to accept it. The tile is then set in " thin set" type grout. Any rough sufaced tile will soon be covered in the alge ect & will prove to be difficult to clean.
I built or had a pond built for my MIL that lives outside of Udon. It is made from grout. The fish & plants do fine in it. It is emptyed & cleaned every once in awhile to keep it fresh due to the weather as expected.
There may be some merit to the notion of lime in cement products. Concrete & grout also contain sands & rocks. Those elements always have a cetian percentage of natural salts. These leach out over time & can cause harm to plants or fish. However cleaning the pond helps wash this out while the clean water allows for some of this leached salt to be diminished. Over time the lime & salts are minimised.
We lost some fish at first but I thought it was more from my MIL not using the water aireation system properly so the oxygen levels fell. Water is pumped though a statue I placed near the pond so it sprays into the pond. It was all new to her so I think it just took time to learn how it all works. We just talked to her & after 3 years she has no problems with the pond or the fish ect.
