Good aquarium maintenance methods will lead to a healthy and balanced aquatic atmosphere and booming fishes, giving years of joy.
Investing half an hour every alternative week on all pond fish tanks seems affordable when compared to money and time spent attempting to solve a problem, which may possibly have been prevented in the first place.
The biggest component for maintenance is tank steadiness.
As long as things are running properly plus your fish are healthy, there is no need for any major changes, even if the pH or hardness seems to be slightly beyond range.
Only increases or decreases of the main water parameters will demand your careful but instant focus.
