    Default Lighting help please


    0 Not allowed!
    Many of you here have seen my 10g tank journal. I have pfs substrate and low light plants with root stick ferts. I have some growth but not phenomenal and I'm wondering about lighting. Right now I have a 10 watt and a 15 watt CFLs. Would it be to much light if I got two 20 watts like this

    Or am I better off sticking with what I've got? I use a multi purpose liquid fert big Al's brand one a week and dose 1/2 cap excel daily.

    Well in my experience the more light the better. Then again Ive had success using as much watts as you are. If you don't mind spending the money I think it may help.

    I guess I'm concerned about having a lot of algae problems if I have to much light.

    I think the CFL that you've linked to is the wrong color temperature for freshwater plant growth and my cause unnecessary algae growth. Do you know the color temperature of the CFLs you're using now? A kelvin rating of 5500 to 6500 k are the best for freshwater plant growth.

    When in doubt, do a water change.

    Yea, look at any store for the CFL bulbs, check on the box for the color temp (K or Kelvin Rating)

    Ideally you want 5500K - 7000K

    I assume this is the bulb - Zoo med ultra sun cfl - http://www.bigalspets.com/6-500k-ult...lamp-10-w.html

    those are 6500k bulbs - 2 of those over a 10 gallon tank I think would give plenty of light?
    Current tanks:
    37G FW - 3 Pearl Gourami, 4 Black Mollies, approximately 20+ Molly Fry, 5 Assassin Snails | 10G Planted FW - 14 Molly Fry, rocks, DW and an Anubias Nana - journal

    Yes that's it, OK wonderful thanks so much. I've tried to wrap my head around the whole lighting/co2/ferts but it just doesn't click. I just need someone to say this is what you need.. Get it.

    More lighting is not necessarily "better". Excess lighting without proper CO2 levels and high enough nutrients is an algae explosion waiting to happen. Algae is set off by an imbalance of nutrients and low CO2 combined....now if you have a long photoperiod or intense lighting that is simply pouring gasoline into the fire. Your algae will have what it needs to over take the tank. I have ran 40watts on a 10G...it was medium lighting. This requires some form of CO2 be it Excel or a DIY setup...and regular fertilization. Is this something that you were wanting to commit to? If not then I would simply stick to around 30watts on the 10G. You can pick up a twin pack of spiral CFLs at Wal-Mart in the daylight 6500K spectrum for around $6. You need to replace these spiral bulbs every 6 months as they tend to wear out quickly.

    Probably the best thing you can do with these incandescent hoods...is to paint the inside of them white. The reason behind this is that the spiral bulbs you are using are not that efficient at reflecting light due to their spiral shape, rays essentially get knocked around all sorts of places. The reflectors in those incandescent hoods also are not that great...they are honestly more of a heat shield than anything. Simply tape up the electrics...remove the reflectors and give it 2 good coats of Krylon fusion white. Once it is dry replace your reflectors(heat shield) and put in a pair if new 13-15watt CFLs. You will see more improvement in lighting from improving your method of reflection than going higher wattage.
