Monitor Tank Health & Ecosystem Management

Last update on 2023-09-19 / Affiliate links / Images from Amazon Product Advertising API

Recently, a friend was curious about why I invest all my energy into a device that is “simply” a monitoring tool.

The question is legit. But, Seneye Reef does more than just monitor the parameters of water. As I stated earlier the power of knowledge is in the mind, as Seneye Reef delivers tank ecosystem insight quickly and effectively.

For me, with an active life that is constantly on the go, automating even the most basic jobs can be beneficial.

If you’ve witnessed an accident with a tank you’re aware of how devastating it can be to witness your hard-earned money go down the drain. In essence, Seneye Reef protects your financial and emotional investment.

With its advanced alarm system for early detection, it will be alerted of an upcoming disaster. This alone makes this system worth every cent.

In addition to its astonishingly precise predictive management system, It can also provide automatic alerts on ammonia levels, water levels as well as pH balance as well as other important tank health indicators via email or telephone.

Together with its graphing and historical screen, Seneye Reef provides a direct link between your and the underwater world.

Seneye Reef monitors the following parameters of the tank:

Water Temperature

A fellow enthusiast took an off-season work trip. Thinking that his tank was properly prepared for the trip the next day, he set off. However, the heater broke just as his plane took off. Without a heater, the tank of his reef fell down to the point of dangerously low temperatures.

When he returned to the reef, he was astonished by the findings he discovered. A majority of his most prized corals died due to the temperature drop. After he fixed the issue, however, it took a long time to see his tank rebound.

If he did have a Seneye Reef monitoring device the alarm could have alerted him to changes in temperature which he then could have requested a friend or family member repair the heater, or make the necessary adjustments.

If chillers or heaters malfunction, fixing temperature stability in the shortest time possible is essential. When using Seneye Reef, the temperature of the water is continuously tracked and visible on the display on your dashboard.

Free Ammonia

Yes, monitoring ammonia levels in a tank with a proven system isn’t a necessity. What’s the reason? In established tanks, ammonia is effectively converted. In my opinion, however, ammonia monitoring is crucial for both established and new tanks.

What happens when a large fish dies, or if your auto feeder is damaged and you don’t notice it immediately? Although they are rare are not uncommon, they can cause established tanks to experience an ammonia increase. It may not be something that you’re concerned about constantly however in some critical circumstances you’ll be glad that you have this.

Acidity Levels, pH, and Levels of Water

These parameters for monitoring are crucial to ensure a healthy, happy tank. Seneye Reef continuously checks pH and levels to ensure that both are in the right range.

Personally, I am awestruck by this feature. It’s comforting that I can open my phone as I’m using Seneye Reef WiFi Server. Seneye Reef WiFi Server and can access vital data.

IMPORTANT: In order to use the ammonia monitoring and pH monitoring capabilities, Seneye Reef requires slides for the controller. The slide is inserted into the device and is continuously monitoring the two parameters.

They’re not expensive and last for approximately one month. It’s easy to find these slides for sale in packs of three slides for $30 which works out to about the equivalent of $10 per month.

Obviously, you don’t need to utilize the slides if don’t care about ammonia and pH monitoring.

Seneye Reef PAR Meter – Illuminating the Vibrant World of Corals

In analyzing Seneye Reef, it was easy to identify the most notable aspect. It has an array of amazing features but its PAR meters are the cherry on the cake.

If you’re not aware, PAR (Photosynthetically Active Radiation) levels are just crucial to the growth of corals as oxygen is to humans. Fundamentally, PAR determines the light availability needed by corals for photosynthesis. Without a reliable measuring system, it’s nearly impossible to precisely adjust the lighting.

One of the biggest errors that almost all aquarists commit is that they adjust their light according to their perception. The need for light exposure isn’t only about quantity or brightness, however, it’s also about quality. In most cases, the quality of light and quantity in aquariums isn’t ideal for optimal photosynthetic processes.

Without going into too much detail Lack of lighting is a sign that the cells’ reactions, also called chloroplast, don’t get activated. This results in reduced growth and lackluster color development.

This is the point at which PAR meters are used.

Since human eyesight is able to see and contrast colors side-by-side but we aren’t able to differentiate between subtle color differences. In addition, it’s virtually impossible to gauge the brightness and the color of the light when lamps are placed close to each other. Thus, the only way to ensure corals get the proper lighting is by using the use of a PAR meter.

By utilizing light sensor technology, Seneye Reef PAR meters provide three main outputs:

  • PAR Spectrum and PAR Seneye Reef monitors PAR and Spectrum both are crucial for the growth of healthy corals.
  • LUX is a measure of the intensity of light to ensure corals have ample illumination to grow without reaching risky exposure levels.
  • Kelvin monitors the hue or color temperature that is present in different places throughout your tank to ensure that the temperature of your aquarium is suitable for your specific corals and the overall health of your tank.

What do to do with this information? Use this data to gain an advantage! PAR Meter readings are saved in the software’s dashboard. I love this feature because it provides an exhaustive history of lighting. This can be helpful when trying to solve specific issues.

For instance, following the addition of many new acroporas into my tank, their color diminished. Utilizing a Seneye Reef PAR meter the readings were way too low. After adjusting the light levels to the proper levels, the color returned within four to five weeks. Without this information, this stunning coral would have gone extinct for good.

The most appealing feature? The PAR meters are extremely simple to use. For the most precise readings, you should direct the lens straight to the source of light. It is important to take multiple readings in various locations throughout your tank. Each time, you need to rotate the meter on its horizontal line (spin it about 180 °). It will provide you with the most precise reading.

After adjusting my PAR by using Seneye Reef, my coral began to bloom. I keep my PAR readings between 300 and 400 seems to be the most effective for my beloved SPS coral. It appears to be growing every day.
