New tank and existing tanks all have one thing in common, lights.  Knowing how your lights perform is not as plug and play as it was before LED lighting.  Thinking about getting a new light and need an experienced professional to shed some light on the topic.  Technical testing from Reeves' Reef will get you dialed in to the setting and spectrum that you need to set it and forget it.  No more guessing how high to turn up your adjustable lights or guessing if your non-adjustable lights are doing the job.  Somewhat new to the marine fish tank hobby? Make the call and sit with someone that cares about getting you started or helping you overcome challenges.  Lighting Services consist of testing the Photosynthetic Active Radiation (PAR) produced by your lights at the primary setting, through your water to the bottom center in your tank.  Also available, A PAR map could be created of your tank so that you will always be able to reference the best light conditions using the primary and an alternate light setting of various locations in your reef.  Also available, A light spectrum graph will ensure that you are producing a correctly dialed in spectrum of light for your tank needs.  Annual testing of this type will also validate the performance of your lighting and water conditions to produce the required PAR and spectrum for your specific tank needs.  General PAR testing, detailed PAR mapping, and spectrum graphing at reasonable prices so you are not in the dark about your lighting's performance.
