Many beginners think tank maintenance means that twice a month, you take out the fish, drain the water, take out the gravel and anything else in the tank, and wash everything except the fish thoroughly! This is rather extreme, and unfortunately, anyone who practices this method will be out of the fish hobby very quickly.
A partial water change takes place when you change a part of the water in your aquarium on a regular basis. The key word here is part. So many novice owners will take out half of the water or more, add back fresh water, and not bother to add any sort of water conditioner. Then they wonder why they usually have a fish death or two after each water change! Novices have been known to exclaim knowingly to others that changing the water in an aquarium will kill your fish!
Nothing could be further from the truth, but unless you know how to change the water properly, it could seem to be true. Your fish may seem to thrive without regular water changes and proper tank maintenance, but they will more than likely be very stressed due to the poor conditions they must live in.
How do you know when it is time to perform this sort of maintenance on your aquarium? Generally, aquarium hobbyists to prevent a drop in the water’s pH, or a spike of the nitrate values will change the water every week or so. If the sides of your tank have started to collect algae, this is another sign that a partial water change is needed. By paying close attention to the appearance of your aquarium, subtle changes are more easily seen.
So, how do we do these partial water changes, and do them correctly? You will need certain equipment to do this job. It is best to have a tool called a gravel siphon to help to drain the water and clean up part of the substrate at the same time. You will also need a couple of buckets, water conditioner, and a scrubbing pad made just for aquarium use.
How much water should be taken from the tank during a partial water change? Most of those who have experience in maintaining fish tanks will say that no more than one-fourth of the total amount of water in the aquarium should be removed. Of course, if you have gone too long between water changes, you may well have to remove more than this amount. This is why it is important to do these changes on a regular basis. Removing too much water stresses out the fish, and also upsets the bacterial balance of the water, which contributes to the stress felt by the fish.
That is why the addition of an EcoBio-Block to your aquarium is one of the best things you can do. The EcoBio-Block not only keeps the tank water crystal clear, but also establishes a friendly and beneficial bacterium that will multiply freely for about two years. Other nutrients and minerals are added to the water as well. You do not have to worry about the bacterial balance with an EcoBio-Block product! This product also dramatically decreases the number of times you will need to do a partial water change and vacuum the gravel. The water stays clean and clear, with no discernable odor, and you have saved both time and money. Using the EcoBio-Block can give the novice to the world of aquariums a good feeling about his new hobby.
