Clams
Are fresh water clams harmful? Someone told me they help to clean the water.

Clams
True, they DO help to clean the water, but one would need to stock
them in a ratio of one for every 2-3 gallons of water for them to have any effect on water clarity... also keeping in mind that they are living, breathing organisms just like the fish and/or snails... remember that they also consume oxygen and contribute to the bio-load in the pond. On top of that, they release insane amounts of contaminants when they die, more so than fish; and it is often difficult to tell when they die as they don't keel over or float like a fish... you'd have to pick each one up and visually inspect (and smell) it to determine whether or not it is still living. Therefore, it would me my recommendation to not keep them, or if you're absolutely bent on doing so, keep just a few as a curiousity. If your pond needs filtration, you would be best off to purchase a good-sized foam filter with a pump sufficient enough to turn over the total volume of your pond twice in an hour. Some disagree with this formula, but I've found it much more effective than lesser GPH to volume ratios. |
