    Hoppy...I just recently set up a planted 36 gallon bowfront tank. I am running a 36" dual lamp T5ho Aquatic Life fixture on it. I'm running the 36" because the 30" only uses 24" bulbs. I have it sitting on top of the tank with the included legs. Is this enough lighting for my tank? I am also running pressurized CO2. I am just wanting to make sure this is enough light to reach all areas of the tank as I have dwarf pennywort that I am wanting to carpet the tank with. Thanks in advance for your advice!

    Blindriver, I am making PAR meters differently now. See http://www.plantedtank.net/forums/sh...d.php?t=615762 The best filter combination I have found for this purpose is Roscolux #4307, #3410, and #38. I haven't yet shipped one to Canada because of the very high postage rate, and the paperwork required, but I may do so in the future. Right now I have stopped making them while my wife and I sell our house and find another place to live, then move there. I suspect that will take up to 3 months. I do plan to resume making them after that.

    I have not been able to design a PAR meter that I can make and have it read correctly without lots of adjusting. There are just too many variables involved. All of those I have made I adjusted to match the readings of a Apogee Quantum par meter.

    Hello Hoppy:

    I would like to say what a great write up you did on how to build a par meter. I have a 250 gallon salt water tank with live coral and have been trying for awhile to find out exactly what the light out put from my bulbs is. and compare I run three 250 watt 14000K double ended Phoenix metal halogen bulbs for lighting. I have read your article and obtained the VTB8441BH diode that you talked about. I have also got the Cinegel samples that you mentioned. Towards the end of your post it appears that you choose only to use the 4815 Rosco filter. Is this correct? I am going to attempt to build one of your devices following the directions you supplied. Also do you know what number diffusers you used is this a trial and error thing? (As per the question below if required could I purchase a Par meter from you and if so how much would it cost? I also live in Canada.

    I haven't shipped any PAR meters to Canada, but I suppose I could figure out how to handle that. It does require that I visit the Post Office each time I do that, and pay whatever they decide to charge me, plus filling out lots of paperwork.

    I'm not making any PAR meters now, instead I am trying a new technique for making the sensors, see http://www.plantedtank.net/forums/sh...=453225&page=3 If that works out I will probably resume making them. You can use a Lux meter, as long as you keep it out of the water. Just divide the lux by 78 to get a fairly good estimate of PAR.

    So are you still selling your meters? What's the cost? And do you ship to canada? Are there similar alternative? Lux meters maybe?

    hitmanx, you can just prop the light across a couple of chairs and measure the PAR out in the air, at the same distance that they would be from the substrate. That reading will be very close to what it is in the tank, in water. If anything it is a big lower than what you get in the water.

    My PAR meter sensors are all waterproof, to the extent that a quick trip into the water shouldn't harm them, but they can't be left in the water for more than a few seconds without some risk of leaks.

    Both the 8.5in and 10.5in domes completely surround the Philips 23w 6500k cfl I am using so all available light is being reflected down. Are your par meters water proof? Could place them directly into my existing tank? I guess this is the only way I will actually know what kind of light levels I am dealing with

    Yes, I did some testing with at 10.5 inch dome reflector. But, I have not compared the light output from the two sizes of reflectors. It isn't an easy thing to figure out, because the smaller dome doesn't completely surround the larger wattage CFL bulbs, making it capture less of the stray light. Intuitively, the 8.5 inch dome should give a higher PAR than the 10.5 inch one, for small CFL bulbs which don't extend out of the dome profile. But, when a bulb does extend out of the dome profile there is a big loss of light.
