    You probably don't remember but you sold me a converted par meter a couple of years ago. Just wanted to drop you a note that I've been using the meter quite a bit recently and I wanted to say thanks for taking the time to make one and ship it out to me. Your par meter has been extremely useful for making making my light intensity adjustments. I really appreciate it and I enjoy reading all of your post. Thanks for sharing all of your thoughts and insight into the planted tank hobby.

    birbaliktanki, go to Ebay and search for "digital lux meter". The first one that came up is the one I have used extensively. Other online stores sell them too.

    You are correct about how to get the lux reading and convert it to PAR. If the room light where you measure the intensity is too low to register more than a few hundred lux by itself, you can just ignore it. Otherwise, subtract it from your readings.

    hi hoppy,

    hope you dont mind me sending you a pm. i saw your post in phil taylors thread and i have a some questions about it.

    can you recommend a decent luxmeter with reasonable price?

    this is what i understood in your procedure, please correct me if im wrong.

    i will take out the lights from the tank and put it somewhere in air. simulate the distance (from lights to substrate) with the test area and run the meter. divide the result by 65 and i will come up more or less with the par level in the tank. does the test area needs to be very dark or brightly lit?

    thanks in advance for your time.

    Thank you Hoppy. I actually ordered a Current Satellite Plus LED for my tank. It had great reviews and claimed to have 35+ PAR at 12 inches. Should work well for my 29 gallon low tech. I figured the money I would save in bulbs and the efficiency of the fixture would be well worth the cost.

    Nazasaki, that light should give you about 40 PAR at 12 inches and 30 PAR at 18 inches. That should work OK for a low light tank. I would use the full spectrum bulb since it has worked for you. The lower PAR will probably slow the growth of the anubias noticeably, but they should still grow well.

    gradstudentnerd, sorry to be a bit late, but I don't monitor this section very often. I think you will get around 45 PAR with that light, which is enough to grow carpet plants. They may try to grow higher than you want, but I have read that people do grow carpets with that much light.

    Thank you for your lighting advice for my low tech 20 long. It's been a month using my single full spectrum T8 and my anubias and marimo are flourishing! I'm ready to move up to a 29 gallon and transfer my plants over (my anubias are a little too tall on the driftwood for the 20L). With this in mind do you belive my t8 will still suffice despite the 6 in height increase? According to your PAR charts I'm okay but I have people recommending T5HO and Planted Plus LED fixtures (way to much light in my opinion!). No CO2 in my tank. Only flourish 3x week.

    If this is the case would it be best to go with a "plant bulb" such as the Aqueon 17 watt Floramax which peaks in all the right spectrums but appears dim to the human eye or stick with my current Aqueon 17watt full spectrum that is the correct spectrum, given me good growth so far but is more "appealing" to us rather than the plants? Thank You!

    Thanks again for your advice on my lightening situation with my 65 gallon tank. I do have one follow up question to my thread: with my AquaticLife Marquis Freshwater 36 Inch Dual Lamp T5 HO Light Fixture above my tank about two inches - if go pressurized co2 and ei dosing regularly, there should be enough light intensity to the bottom of the substrate to my light, lets say total 24 inches to grow things such as pearl weed right?
