Oxygen is one of, if not the most vital element on the face of this Earth. Read any science journal you can find or even look it up on the Internet. You're not going to find anyone that will dispute that fact. The truth is that oxygen is vital to many different organisms on Earth, not just humans.
Our watery friends are no different. They just get the oxygen from a slightly different source than we do. Fish and aquatic plants get oxygen from the water, so your pond is bursting with life because of the oxygen in and around it.
Some way to tell if your fish need more Oxygen
If you catch fish in Carlisle, Mechanicsburg, Harrisburg and Hershey PA gasping for oxygen at the water, you may want to look into the oxygen level. There are a couple test kits on the market that can help you find out if your pond is up to par with oxygen.
Finally, don't forget that ponds are meant to be a relaxing oasis, providing relief from the troubles of the day. Running out and testing a pond every day is not relaxing. If the oxygen level in the pond is good, there's no need to try to improve the levels. The fish and plants in the pond get used to their surroundings and have probably already adjusted to the pond's chemistry. Just remember that favorite pond pets are just like you, living and breathing the same air ... just a little bit differently! We at Gordon's Pond Utopia care about your fish.
Yes, the formula for water is H2O, but the formula's oxygen contribution alone isn't the only oxygen present in your pond. Just because oxygen is a part of the formula, doesn't mean there's enough of it to sustain aquatic life. The oxygen actually comes from several different sources, but the most common is good old-fashioned absorption. Oxygen from the atmosphere is absorbed into the water. Agitation at the surface and splashing (as in a waterfall or pond aerator) increases the absorption of that oxygen into the water because of the expanded surface area created.
Another way that oxygen gets into the water in Carlisle, Mechanicsburg, Harrisburg and Hershey PA is through aquatic plants, but you certainly can't rely on aquatic plants to do all the work. It's a double-edged sword, really. Lots of folks know that plants with submerged foliage can produce massive amounts of oxygen. When the sun shines on them, they use carbon dioxide and produce oxygen. But plants don't grow much by day, so they store that energy. When they grow at night, they use that stored energy, producing carbon dioxide and using up oxygen. In other words, when nighttime hits, submerged plants (a.k.a. oygenators) are not your fishes' friends.
Some of the best oxygenators (also known as submerged aquatics) are fast growing plants with lush foliage that grows under the water line, including anacharis, elodea, and cabomba, as well as a not-so-favorite plant, algae.
Where Does It Go?
Hot weather isn't the only villain in the dissolved oxygen saga. There are a few common ways that oxygen levels get reduced. The most obvious is fish and plant respiration, which is why it's so important to make sure you don't overstock your pond. One inch of fish per square foot of pond is the recommended stocking number, keeping in mind that fish grow and you need to save room for them.
Bacteria are also culprits in oxygen respiration, and beneficial bacteria have especially voracious metabolisms when it comes to consuming oxygen. Your pond's bacterial flora consumes more oxygen than your fish could ever attempt. So basically, the very things you need and want in a pond consume the most oxygen. Isn't that ironic?
Less common ways that may cause dissolved oxygen levels to fall include decaying algae, treating with chemicals, and the depth of your pond. Algae eats up oxygen as it rots away, consuming massive amounts of the precious element. If your fish are sick, you may also want to keep an eye on the oxygen level of the water. The use of certain chemicals in the pond for treating fish diseases can consume a lot of oxygen. It's a good idea to agitate the water while treating the fish.
Also, the depth of your pond plays a role in the available oxygen in the pond. Ponds over five feet deep, for example, will have low dissolved oxygen levels at the bottom. This will be true unless there is a means to bring the bottom layer of water to the surface.
Pond owners in colder climates always seem to get the short end of the stick in other areas of water gardening, but in the case of oxygen levels in backyard water features, they've got a bit of an edge. In case you don't remember from Chemistry 101, colder water (under 60° F) dissolves (or carries) more oxygen.
Regardless of whether you're in a warm or cool climate, you'll want to be careful with your fish during clean-outs. Putting fish in a tank or tub in the heat of summer for a clean-out can be risky. If you don't aerate or agitate the tank or vat, or the tank or vat is in the sun and heating up, your fish may be in danger due to low oxygen levels. You can simply aerate or agitate water that's over 75° F. An air stone makes this task simple and easy. For a little extra help from Mother Nature, pick a nice, shady spot for the fish to hang out while you do the dirty work!
Fish Pond Algae Control in Carlisle, Mechanicsburg, Harrisburg & Hershey PA.
Fish Pond Algae one of the most common problems pond owners in Carlisle, Mechanicsburg, Harrisburg & Hershey PA will face with their ponds. So understanding the basic pond algae is half the battle this will save you time, money and frustration in your water gardening experience.
Common Pond Algae Issues
Improper Pond Circulation
Poor pond circulation occurs usually when encountered with the cost of replacing a burnt out pond pump. Most often people opt for a smaller pump to save money, but ultimately cause major circulation issues, which then they battle with endless additives and mixtures trying to solve a problem caused by less circulation.
The improper usage or complete lack of natural water treatments promotes pond algae. A pond is only as healthy as the water in it. Gordon's Pond Utopia carries a full selection of pond water treatments necessary to create a balanced, healthy, and happy pond. Treating pond algae with pond chemicals is not a long term solution to this pond problem. It’s a quick fix that puts additional stress and loads on your pond. So take care and read all directions before just dumping into your pond.
Lack Of Routine Maintenance
Unfortunately with pond filtration systems that look like pool filter, regular back-washing and refilling expelled water can put a strain on your free time, and make it easy to neglect, causing a backup of alternate issues that compound themselves in multiples. You see green water, we see crashed ecosystems.
Too Many Fish or Over Feeding
Ponds that are overstocked with too many fish certainly promote pond algae.(A rule of thumb is one inch of fish for every 100 gallon of water in your pond) It is so tempting to buy and buy not forgetting that the koi we buy are babies. As it grows we have even more acute lack of space and process ever growing waste. Imagine a 4 inch baby has grown to 1 foot, 3 times in few months! The end result is increasing nitrogen levels, which in turn becomes nutrients for algae blooms.
Improper/Not Enough Filtration
Contrary to popular belief, a pump sitting at the bottom of your pond is not an actual working filter. Most pieced together ponds have a mix match of products in hopes of proper filtration. Their are many systems that work really well, but they all take a pre-set amount of routine maintenance.
