Do I really need to adjust my water’s pH level? | Decorative Ponds & Water Gardens Q & A

Do I really need to adjust my water's pH level?

Q: Do I really need to adjust my water’s pH level?

Terry – Bishopville, MD

A: Sure, you’ve seen those pH tests, like the Pondcare® Master Test Kit, online or at your local pond supply shop, and you’ve overheard veteran pond keepers talking about pH level adjustments. But what in the world is pH and why would want to monkey with it in your water garden or fish pond?

pH Defined

In super simple terms, pH, which stands for potential hydrogen, is a measure of how acidic or alkaline a water body is on a scale from 0 to 14. Pure water is neutral. It has a pH close to 7.0 at 77 degrees F. Blood is also close to neutral. Ammonia’s pH is ~11, which is high on the alkaline charts, while stomach acid’s pH is ~1, which acidic enough to burn through your chewed-up chow.

pH in Your Pond

So why is the pH level in a pond or water garden such a hot topic? Because pH affects the health of those things swimming around in the water. Fish love a liquid environment that strikes the right balance between acid and base. Your pond’s pH level affects their ability to reproduce, to fight disease, to metabolize their food – to do just about everything. The pH level also affects the health of your plants, frogs, turtles and any other living critters that call your pond home.

Adjusting to a Proper pH

Don’t worry: You don’t have to keep your pond at a perfect 7.0 pH all the time. In fact, an acceptable pH reading for a pond is 6.5 – 8.5. But you should use caution when adjusting it because doing so rapidly can harm your aquatic life. If you absolutely must adjust your pH using a pH Stabilizer like pH Lift or pH Drop, apply enough treatment to shift the levels 0.5 at a time, wait several hours before re-treating, and test the waters often with your Pondcare Master Test Kit.

Why Does Algae Keep Growing In My Pond, Even After I Treat With Algaecides? | Ponds & Lakes Q&A

Q: Why does algae keep growing in my pond, even after I treat with algaecides?

Cathy – Bagley, WI

A: Algae seems to take on a life of its own sometimes, doesn’t it? Once that green slimy, stringy or seaweed-looking stuff crops up, it keeps growing and growing until you wind up with a messy situation in your pond or lake. Even if you treat it with algaecides, it still grows back.

Turns out that all these tiny plants need to grow is sunlight and food source – both of which are abundant during certain sunny times of year and when there’s a healthy mix of detritus built up along the bottom of the lake. To make things worse (or better for the algae!), when a pond is treated with chemicals, the process just adds dead algae to the pond, which is actually a food source for the growing algae.

Rather than battle this green monster after it has a foothold, it’s best to take a proactive approach. After you verify that you’re dealing with algae and not weeds (read here for a quick lesson on chara and other types of algae), we recommend you follow these four all-natural steps for preventing algae attacks:

1. Use Aeration: Aeration systems, like Airmax Aeration®, circulates debris that has accumulated in the lake or pond so it doesn’t settle at the bottom and become algae food. Aeration also spreads the debris throughout the water column, making it more accessible to beneficial bacteria that break it down.

2. Use Natural Bacteria: Natural beneficial bacteria, such as Pond Logic® PondClear™ Beneficial Bacteria, power through nitrates, breaking down fish waste, leaves and other organics that accumulate in the pond. This naturally improves the water clarity as the bacteria devour the sediment.

3. Use EcoBoost™: Pond Logic® EcoBoost™ Bacteria Enhancer is an innovative product that binds algae-feeding phosphates in ponds and stimulates the growth of essential beneficial bacteria, which are essential when controlling algae in your lake or pond.

4. Use Pond Dye: Because algae thrive in sunlight, Pond Dye filters those rays and stops them from reaching below the surface, thereby preventing algae from growing. Plus, the cool colors mask the soupy green hue of the algae.

We can’t guarantee your algae problem will disappear, but if you follow these steps you’ll be creating a pond that’s inhospitable to algae invaders.
