Aqua Ultraviolet UV Series Test

Aqua Ultraviolet UV Series Test By Manufacturer

Real Science . Not Science Fiction

At Aqua Ultraviolet as with any successful business, competitors will attempt to mimic your products. While the old adage states “imitation is the sincerest form of flattery,” some of our competitors marketing claims have unfairly maligned our products and distorted the facts.

If you follow our competitor’s information then our units shouldn’t work at all, we wouldn’t even be in business, and yet we are number #1 year after year. Aqua Ultraviolet designs, tests and brings to market innovative products each year while our competitors criticize, then copy us.

We sympathize with the competition, how can they possibly market against the best? By making misleading claims about lamp performance, ultraviolet exposure, and chamber design, they are basically creating propaganda.

Let us give you the facts.

Simply put, Aqua Ultraviolet sterilizers will clear your water in 3 to 5 days, sometimes overnight and keep it that way. We don’t require you to slow your flow rates down to accommodate dirty green water; we eliminate it.

Aqua Ultraviolet has been in business for over 27 years, we have designed units for many industries including drinking water purification, food preparation and manufacturing applications. Remember that in many of these industries the specifications are very stringent. Some of our competitors, have even sought us out to design and produce UV’s for them.

Why do our products trump the competition? Here are a few reasons:

  • Our UV sterilizers are easier to use than the competitions, and they offer a longer lamp life – 14 months over about 9 months for the competition.
  • Our products are generational. We keep parts and supplies for all models, and the parts will always work within the generations.
  • Our high-powered units are compact. The competition’s are larger and need more space for installation.
  • Our lamps are rated at the end of life, not at the beginning.
  • Our initial testing is performed in-house and field tested, and then results are verified by independently laboratories. Therefore, the testing is fair and unbiased.
  • Our products come with Technical support people to help with installation questions and other inquiries.
  • Our technical support staff has even assisted consumers with competitors products.
  • A live person is available Monday through Friday 8:00 am to 4:30 pm.

Hand Feeding Koi Instructions

hikari_adL

Steps to Hand Feeding Koi

Choose the right Koi
Some Koi tolerate human presence more than others and some Koi are not shy about coming close. Koi are very sociable fish that live in harmony with humans that are very happy to get close, and will often take food from a human hand.
Select the feeding place
Whether it is going to be your own pond, your aquarium tank or even a local park, it is important to choose one place that you will always treat as your “feeding spot”. The feeding spot should be free of sudden noises (such as splashing water), sudden movements (such as other humans walking by) and too much light/shade contrast.
Start slowly
At first, just throw the fish food into the water and observe the Koi as they eat. Make your presence obvious (that is, don’t move away). The first Koi to eat will be those that are bravest. Their determination to eat will encourage the less courageous to come along later. You may need to repeat this process of the Koi just getting used to your presence several times.
Move your hand closer to the Koi as they feed
After a few tries with you standing close to the Koi, start to stretch out your hand towards them. Leave it hovering above them for a short time as they feed, so that they can see it.
Try food in your hand once you feel certain that the Koi are used to your presence and your hand
One way to observe their familiarity with you is when you see the Koi getting excited by your presence, as they have come to associate your being around with receiving food. Do this at the same time as your other attempts at getting the Koi used to you, with the same food and in the same place as before.
Set your hand into the water, and doesn’t make fast movements or the Koi won’t take the food
Release some of the food into the water and leave your hand outstretched with some food still in it. Wait for the boldest Koi to come close. Again, this may take several attempts before the Koi feel comfortable enough to share from your hand.
Continue the feeding by hand regularly
If you want to continue feeding your Koi by hand, practice it regularly so that they remain friendly towards you and are not scared by your hand. It remains important to keep a regular method so that the Koi are not spooked; this is less a problem once koi are trained but might be a problem with smaller, more delicate Koi.

Feeding Koi Recommendation

Steps to Feed Koi

Take the temperature of the water your Koi is living in
Because Koi only eat certain foods in certain temperature.
If the water is under 70 degrees Fahrenheit, feed it once per day or every other day
When the temp lowers to 63 Fahrenheit or lower, feed it every other day. Another option is to feed it a cereal-based diet because cereal breaks down quickly.
In warm water
Koi under 8 inches in length should eat around 5 percent of their own body weight, while Koi over eight inches in length should only eat around two percent of their own body weight.
Provide the nutrition your Koi need
A healthy Koi often have brighter colors than a malnourished one. While your koi can’t just live on live food alone, your koi should enjoy the treats now and then. There are earthworms, which is the favorite of koi, prawns or cockles.
Use koi food in pellet form for their main diet
While Koi eat everything you gave them, most aren’t nutritional and can harm them.
