Lifer Posted December 31, 2021 Share Posted December 31, 2021 (edited) Link: PAR Mapper Tool After clicking the link, you should see a preview of the PAR Mapper in Google Sheets. Click the "Use Template" Button in the upper right hand corner. This will copy and save the template under your own Google profile. Instructions are provided with the PAR Mapper Tool. Send me a PM with any issues or feedback. Original Post Below: I recently borrowed the club meter and wanted to map out my tank's PAR like on the BRS videos. I recorded 20 PAR measurements in a 4 x 5 grid about 8 inches below the surface and then used interpolation to create this map in Google Sheets. Red are higher-PAR hot spots, blue are lower-PAR cool spots, and white are average PAR values. I have a T5 hybrid, and the mapping suggests that the front 2 tubes (ATI blue plus) are brighter than the back 2 (one ATI blue plus and one actinic). The left LED puck is also brighter that the right one (despite identical settings). This creates higher PAR on the left hand side of the tank and the hot spot in the left front. I can share the Google Sheet if anyone is interested. I've set it up to be fairly autmotated, so all you need to do is plug in your PAR values and the x,y location in the tank.

Lifer Posted January 2, 2022 Author Share Posted January 2, 2022 Hey @Parzifal, I updated the original post and added a link to the PAR Mapper Tool. Check it out and let me know what you think. I've never really used Google Sheets before, and tried to make it a template so others could save it and modify it. I'm keen on seeing if it actually works!

You can’t just put your monitor outside in full sun and call it energy efficient lighting. Quote Link to comment Share on other sites More sharing options...

True enough. nor should energy efficiency be a primary consideration when choosing a coral light... Heat your tank with lights or heat it with heaters. Either way, your going to pay.

John Vinson Posted January 16, 2022 Share Posted January 16, 2022 yikes...my light setup is crap! I just did some preliminary testes with a PAR meter and the best I got was about 155 at the closest to the lights in the middle of the tank....went all the way down to 35 by the sand bed......glad I'm swapping to the StevesLED upgrade tomorrow LOL Quote Link to comment Share on other sites More sharing options...
