"One of the first things that you need to look at, is the location of nearby trees. Falling leaves can be a disaster in a pond
, and will quickly foul the water if you don’t keep on top of removing them. That’s not to say that ponds have to be located far away from any trees – they just need to located strategically where few branches will directly overhang the pond."
"The amount of sunlight that the ponds receives is also something that you need to take into consideration, and ideally you want the pond to received between 4-6 hours of direct sunlight every day. However, if the pond receives more than 8 hours of direct sunlight, you will likely experience temperature fluctuations and algae overgrowth
in the ponds. If it does receive more than 8 hours of sunlight, make sure that at least part of the pond is shaded to provide shelter for the fish."
I like my way of stating this, short and sweet.
As I said algae needs nutrients and light to grow, this is a fact... Excess light alone simply does not equal a green pond as you stated, and the website you quoted even supports that argument by stating "can be" and "you will likely" not that it will...
Incidentally I disagree with the 4-6 hours of sunlight. A good pond will be one that stays in shade all day, but is not under overhanging branches. There is never a shortage of indirect sunlight and plants grow just fine in the shade.
As someone who has done their fair share of growing plants in ponds, aquariums, as well as gardening both indoor and outdoor, shade, indirect light and/or low light levels is simply not sufficient for many types of plants, thus many plants will not grow 'just fine' in shade, indirect light or low light levels, this is especially true in regards to many aquatic plants that really need several hours of direct sun light to thrive... Even common pond plants like many water lilies are known to be high light requirement plants that need direct sun to thrive, sure some can handle shade but not all, and many simply won't thrive without the direct sunlight... Feel free to Google aquatic pond plants and direct sunlight, you will probably discover that the general consensus is 4-6 hours of direct sunlight for most, and that is likely why the site you quoted suggested such...
Because ponds generally have so very many nutrients for algae to eat, the slightest direct sun will cause too much algae.
If your pond has an excess of nutrients in the water, it''s not being properly maintained and filtered, a properly maintained pond simply won't have excess nutrients that allows for an algae bloom that turns the water green... And it does not necessarily require a lot of labor or maintenance to maintain the water parameters if you design and setup the filtration and choose the proper amount and type of life in the pond... If setup properly you can create a pretty stable ecosystem in a pond that maintains itself for the most part...
I agree, people can either follow my golden rules of pond building or spend their pond as if it was a people pond. Personally I wouldn't think a pond is worth all the effort, that's why I give the golden rules, to avoid that effort. But I agree, you can do pool cleaning for a pond if you want to position the pond in the wrong place. Some people like cleaning pools, I say great !
Sorry but I don't consider your advice as a the 'golden rule' or agree that not following it equates to positioning your pond in the "wrong place"... Not following your rules does not equate to endless hours "maintaining" and "filtering" or the pond being in the "wrong place" pond positioning is not that dichotomous...
I'm a firm believer that if you are unwilling to devote the time to maintain and provide for your pets then you should not have them, and that includes having a pond with live animals and plants in it...Edited by MeepBeep - 12/17/15 at 1:48pm
