Dissolved Oxygen Testing Kit

It easily could be said that few things are more important to having a healthy, vibrant, well balanced pond more than abundant levels of dissolved oxygen in the water. There is no greater asset for fish, and their welfare, than good oxygen levels.

In consulting with many pond owners over the years, there's been a prevailing assumption by many that there are adequate amounts of oxygen in their ponds. And while this certainly might be true in many cases, others are basing their beliefs on nothing more than an assumption.

And this is dangerous.

When oxygen levels get low, for one reason or another, it's usually the fish that suffer more than anything. The larger fish go first, because they need more oxygen to survive...and in worst case scenarios, many or all the fish in a pond can die quickly when oxygen becomes depleted.

Low dissolved oxygen levels get more common as the temperature rises. Pond water simply can't hold as much oxygen in temps above 78 degrees. Also the daily cycle of plant life affects this as well. As plants thrive in the sunlight, they release oxygen into the water, and at night or in particular, when they die off, they pull oxygen from the water.

In almost every case, if someone is treating an algae or weed problem with a chemical, it's highly recommended to have good aeration running at the time. Bacteria as well must have good levels of oxygen to thrive, and without it they simply won't be able to do their important janitorial work in the pond.

Because of these things, we often suggest supplementing with mechanical aeration.

For many folks however, this can be a hard pill to swallow because a good aeration kit can cost a bit of money...and even if it does represent the best investment one can make in their pond, how can you know if you really need it?

We've searched far and wide to find a reliable, affordable, and accurate test for measuring dissolved oxygen in pond water. We looked at digital meters, which are great, but really expensive. And we looked at inexpensive test strips that were sometimes sketchy in the results and often they were hard to get ahold of in ample quantities.

In a perfect world, every pond owner would have a high end, digital oxygen meter that could measure the amounts at various levels of the pond and in particular at the deeper parts. If you'd like our recommendations on something like this be sure to contact us for more information.

For practical purposes and for something most pond owners would find useful, we've found a more realistic solution.

In our research we eventually discovered a really good test kit that will measure dissolved oxygen and it will do so quite accurately without spending hundreds of dollars. Now every pond owner can have a tool to truly tell just how much dissolved oxygen is in their pond and you'll be able to stay ahead of problems with some routine monitoring.
