I use my Apogee PAR meter to measure different places inside the tank to show how the light varies around different areas in a planted tank. Notice how incredibly much just a few plants drop the intensity.
The lighting is 2x24 watts of T5 HO Philips Aquarelle from an Aquamedic Sunbeam with reflectors.

  • Thanks, I've never seen an instrument like that at work!

    What are you using for illumination on that tank?

  • @claudiodelaplata 2x24 watts of HO T5. Not sure about the bulbs. One Philips Aquarelle and one Deltec Midday I think.

  • Hey, I just learned about this PAR meters. Are they expensive? I would like to buy one to see how my planted tanks are doing. Can you e-mail me the site where you got yours or post it here?

    Thanks,

    Great video by the way.

  • @AdrienBCaldwell Sure, put the following into Google "Apogee Instruments Quantum Sensor: MEASURING PPF" and click "I'm feeling lucky".

  • whats dat thing for

  • It measures photon flux inside the tank which enables me to see how much active radiation is available for photosynthesis. Around 40-50 micro moles per square metre is good for a normal planted tank. I like around 100 to get the Hemianthus growing fast.

see all

    Thanks for the response. But I pasted what you told me to Google and I did not find the "I'm feeling lucky." part to click on. But looks like I will be off to a good start. :)

    This was a great video by the way. I cannot wait to try one to see if my compact fluorescent bulbs are suitable for my planted tanks.

  • good job bro. i hope my planted tank would suceed as you did.

  • Very very interesting.

    Thank you for sharing the result of this experiment
