5 Best PAR Meter For Reef Tank: Reviews & Top Picks

If you own a coral reef tank that is brimming with corals, then you’re probably aware that picking the best PAR meter for reef tank and maintaining the tank in good condition can be a bit more difficult than you thought.

Reef tanks can be quite difficult to maintain particularly when they are unable to provide your corals with ideal conditions for growth and longevity.

For corals, one of the main aspects they have to be able to perform to live is photosynthesis which is why, without this process, they’ll certainly end up dying.

But, how do you determine whether your corals are receiving the right amount of sunlight to remain healthy and happy?

Here is the point an area where the PAR meter is considered. Let’s look at the meaning of a PAR meter as well as our goal to help you choose the most effective PAR meter for reef tanks (this one is our favorite), we have selected our top three that we’ve reviewed in great detail.

What Does A PAR Meter Do?

Before we get into the details of the function of a par meter and the meaning behind it that it does, let us know the meaning of par, particularly in relation to your reef tank and your corals. PAR is a short form for Photosynthetically Active Radiation.

In simple terms in the context of tank reefs, PAR represents the light intensity that enters the water column, and it is accessible to corals to produce photosynthesis.

As you may have guessed, the majority of the food that corals make or consume is created by photosynthesis. If there’s not sufficient PAR or excessive amounts corals are not doing very well.

A PAR meter is a device that measures the amount of light radiation, or PAR that is available to corals to make use of for photosynthesis. In terms of maintaining the coral’s health, this is crucial.

Many have started making use of these devices to boost coral growth and boost the overall condition of the reef tank.

For your information that for optimal growth, some corals require only 40 PAR for basic survival While others may require up to 600 PAR.

5 Best Par Meter For Reef Tanks

Let’s look at our opinion of the top 5 best par meter for reef tank available today.

Any of these options could just be the best option for you, the instrument is needed to determine the amount of light that your corals are receiving.

The purpose of this is to optimize the amount of beneficial light radiation that corals receive to ensure their growth.

1. SENEYE Reef Aquarium Monitor And Par Meter

When it comes to monitoring capabilities In terms of monitoring capabilities, it is the SENEYE Aquarium Monitor is certainly one of the most effective alternatives, in our opinion.

We do believe that the particular unit has been classified as one of the most precise and complete alternatives.

Seneye PAR meter is known for being extremely precise and precise in all its measurements. This is crucial in maintaining the condition of your own coral reef.

The fact that it’s so precise when it comes to measuring different water parameters is an important point, absolutely.

The most impressive feature of this particular piece is that it does much more than just measure the PAR.

It also measures the LUX as well as the Kelvin within the tank also, or more specifically the Kelvin range the lights in your system are located in and how well the lights are performing or changing in time.

As a side note, although corals are saltwater species, however, they can be used to build freshwater tanks.

Seneye PAR meter can do even more since it tracks the temperature so that you know when you’re drinking water that’s too hot as well as cold. It can also tell if the heater or cooler is breaking down.

It can also monitor ammonia and nitrate levels within the water, in addition to it can also monitor the pH level and the water’s levels.

In essence, it can keep all of one of the water parameters that are essential for the survival and health of your corals.

We like the way this product was designed to last and appears to have a decent shelf life.

What must be noted in this case is Seneye Slide must be replaced each month to allow it to be able for this PAR meter to keep working and that’s no huge deal.

Remember that this gadget works via a USB connection, but does not possess any display of its own.

This means you have to take the data collection with this device, but you must also link it up to your laptop using the supplied USB cable to examine the information. Unless you purchase some additional accessories, you are not able to utilize your smartphone to look at the data, but only your computer.

Pros

  • Extremely precise measurements.
  • Durable design.
  • Data is easy to read on your laptop.
  • Measures LUX, Kelvin, & PAR.
  • Analyzes Nitrates, Ammonia pH, Temperature, and Water Level.

Contrary to the PAR meter we examined it is the Sun System PAR Meter particular one is extremely simple.

It doesn’t determine anything other than the PAR level that your corals are receiving. It does not gauge ammonia, pH, temperature, or any other parameters of the water that the model above measures.

However, even though it is a one-trick pony, so to be precise, it can do the job well. It is very precise in its assessments which is an essential aspect of the course.

The Sun System PAR Meter is extremely easy to use. Simply place the probe in the water, and wait for an hour for the readings to be read.

Its nifty part here is that this item comes with its own display and screen.

This PAR meter would only give its results when you connect to the computer through the USB port.

But, it is extremely quick and simple to use due to the fact that it comes with its own display, which is directly connected to the probe.

Make sure you don’t drop the display into the water since it’s not waterproof. The display, though it is functional, it is not the most durable. Additionally, it doesn’t keep track of past and current information, which could be somewhat of a problem.

Pros

  • Very easy and simple.
  • Readings that are accurate.
  • It comes with its own display.

Cons

  • The display isn’t particularly sturdy or waterproof.

Best PAR Meter for Reef Tank Aquarium

FAQs

What is a Good PAR for a Reef Tank?

As the general rule corals require these PAR levels Soft Corals (zoanthids palythoa, zoanthids, mushrooms as well as leathers): 50-150 PAR. LPS Corals: 50-150 PAR. The Hard Corals (stony corals Small polyps): 200-500 PAR.

How Much PAR is Too Much Reef Tank?

A lot of light can hinder or harm corals. There’s no definitive guideline for the best PAR for all corals, however, an ideal starting place would be 150 to 250 PAR.

How Much PAR Do I Need for Torch Coral?

A proper hammer coral maintenance program is dependent on complying with a PAR rating that is generalized to a low level of light. This is between 50 to 150 PAR and you will be able to identify this by purchasing a PAR meter.

Is LUX the Same as PAR?

LUX, as well as PAR, are different. LUX meters determine the amount of light that is usable for humans, whereas PAR meters determine a spectral range that includes the number of photons that hit the plants in a single second within the spectrum.

Can I Use a LUX Meter to Measure PAR?

At the top of each chart is the amount to be applied to each Luxmeter to translate the readout of lux to PAR in units of umols/m2/sec.
For example, if using a UNI-T lux meter and you have a red and white LED grow light, you will multiply your LUX measurement by 0.017 to calculate an equivalent PAR. PAR equivalent.

How Many LUX is a PAR?

It appears to me that the LUX conversion to PAR conversion process is more difficult in the case of LED light bulbs. Simply multiply the LUX measurement by 3.05 to calculate PARS.

Conclusion

In addition, the amount of sunlight your corals receive in your reef tank is vital and directly connected to their existence. If they don’t have enough light, they’ll not be able to produce their own food or develop, however, too much of it, and they’ll become overwhelmed.

A best PAR Meter for reef tank will be able to determine precisely the amount of light your corals receive and allow you to make the necessary adjustments to encourage the healthy growth and development of your coral. Personally, we would suggest using one of these PAR meters that we have reviewed since they seem to be among the top ones.
