    Hi Hoppy, I was wondering if you could check out my lighting question if you get a minute.-

    http://www.plantedtank.net/forums/sh...d.php?t=185831

    I've been trying to read through you older posts and it seems that in your opinion a T8 is enough for a 12" deep tank with low light plants. I guess my question to you is, are the marineland T8 fixtures ok, and would you recommend 1 or 2 of them for a 20 long 30"x12"x12". I would also love to get your opinon on bulb choices, I listed several of them in the thread. Thanks in advance if you find the time to help.

    When I quit using a drop checker I was using 1.7 dKH standard solution instead of 4 dKH. That would be yellow at around 30 ppm of CO2. When I was doing that I was using DIY CO2, as I am now, and with that you don't need to get too concerned about having too much CO2, but I liked being able to see that I had a significant amount, using 1.7 dKH. All of this was over a year ago, and my memory isn't good enough now to remember all of the details.

    Thanks. Any advice on calibrating the drop checker to be bright yellow when at 30ppm instead of green?

    I don't think I wrote a "guide" on the drop checker. That was long enough ago that I kind of forget just what I did. There is a thread in the DIY forum about it though.

    Hey Hoppy, did you ever write a guide on that DIY drop checker? I'd like to make one for myself, I love the look.

    You can light a standard 55 gallon tank with one T5HO bulb, in a good quality light, for example http://www.catalinaaquarium.com/stor...oducts_id=1837 This should give you medium to high medium light with it sitting on top of the tank. Using the feet it can be purchased with it should give low medium to medium light.

    LED lights have some advantages, but cost a lot more than T5HO. The Marineland Double Bright, 48-60 inch light should give you good low light. Or, you can DIY a custom light to get whatever intensity you want, with a dimmer so you can adjust the brightness. That is the best light for functionality, but can be pretty expensive too, perhaps $200-$300, and you first need to learn how to design and build it.

    Hi Hoppy, I'm glad I found your posts, I hope you can shed some light on my situation (mind the pun).
    I have a 55gallon fresh water tank, I currently use the regular LED lights that came with my starter kit and am keeping low light plants for now. I would like to upgrade the lighting to be able to keep more interesting/prettier plants.
    I'm getting a lot of contradicting information from my research on the internet as to what type of lighting to get, flluorescent vs LED's. I need a light strong enough to reach the depth of 24" and am overwhelmed by various considerations such as watts/PARS/kelvin/lumens/colour temperature...
    People who have fluorescent swear by it and say absolutely do not get LEDs and those with LEDs strongly urge the use of those.
    I found your charts and thought maybe you could help since you seem to know a great deal.
    Thanks so much for your time. My fish, plants and I appreciate any help

    If I were you I wouldn't use any driver that isn't dimmable. There aren't a lot of them available for that much current, but there should be a Meanwell one that is the same as that only dimmable. I think I would keep the two rows of LEDs closer together, and rely on the spread of light to get the whole substrate lighted. If you use 60 degree optics you should be able to light the whole tank with the rows about 5-6 inches apart. And, for that a single heatsink about 6+ inches wide would work. For that much current the heatsink needs to be a good one, and some fan cooling will probably be needed. If you use the calculator spreadsheet in http://www.plantedtank.net/forums/di...-tank-led.html you will know all that I know about how much PAR you can expect.
