|james1542||Glad I could help make sense of it. Don't worry you can beat BBA!|

Did I say it's maddening?

Thank you for the considered answer you gave. I am always being scolded about light/fert vis-a-vis CO2 and so this approach with high light and root ferts interests me, if not for any other reason than that it broadens my education.
I have yet to bring it to the cognoscenti here because I'm afraid I'll get blasted out of the room with why I'm wrongs, but I have a typical pressurized CO2 setup with a cerges reactor on a closed loop spray bar being pushed with a Mag 7 pump choked back enough to keep the tank from looking like 7-Up. Drop checker YELLOW on opposite side of 40b from spray bar. Excellent circulation via FX5/spraybar, etc..
I get BBA GROWING on the CO2 spray bar! I received a batch of plants from someone who was tearing their tank down and with these plants were a few patches of HG that had a tiny little bit of BBA in it. BIGGEST MISTAKE was thinking "oh I'll just tweeze it out" when I put it in my tank. One year later and this stuff is like a 50's monster movie and nothing I have been able to do has curtailed it any.. All I can do at this point is pluck plant leaves and scrape it off walls and fixtures. This is all with three 23w 6500 twist CFLs on about 8.5 hrs a day...

|james1542||Oh and I guess I never really answered why do this... I've never come across a tank yet that I felt had so much light that is was unpleasant to look at (unless the light is shining in your eyes).|

Moose I don't know if this much light would work with the EI, or any water column fert regime-without resulting in algae soup, For me I get away with high light, but my strategy is to have lots of plants, and keep the water column fairly sterile and keep the nutrients in the substrate. Now this may rule out some plant species all together, especially if CO2 is not used. I think being conservative with bioload and photoperiod are also important when playing with fire to keep the right balance.
Consider it a diffrent strategy perhaps. It could go horribly wrong if you are not careful, but it can be done and there are lots of examples on here, even sans CO2.

Ok maybe I'm missing something here (wouldn't be the first time LOL!) but that 3w led unit seems like a dumptruck load of light for a planted tank of any normal depth. This other thread talking about 20, 30 and even 40w led outdoor spot lamps...I don't get it...Seems to me that unless you have pretty awesome luck you're just asking for an algae machine.
Someone care to give me the Reader's Digest version of why this much light is desirable?

Aquatraders doesn't offer too many sizes in the freshwater spectrum though, check amazon and [Ebay Link Removed] That being said I've read some bad reviews on them. Once those LED's fail, maybe you can just replace them? Quite a bit of bang for the buck though.

Look at this one then?

I wonder if you saw these? People on the East Coast Cichlids forum seem to think they're pretty ok./QUOTE]
It might be ok for a fish tank light. It is no where near a planted tank light.
Each LED is a .05 mW unit. No comparison to strings of 3 watt emitters.

I'm dosing with flourish every few days and I've started adding root tabs.

I was considering this for the 20l
And this for the 29g
Am I still way overshooting the target here?

|fermentedhiker||Have you looked at the finnex fixtures? the fugeray would work I think for you setups(and be within your budget) assuming you don't add CO2 and the Ray2 fixture should work if you do. Just a thought. I just started using a Ray2 on my 40B so it's too soon to tell you how good it is, but it seems to be pretty good so far.|

|kevmo911||Remember that 20L's are really shallow. You'll probably end up being amazed at how easy it is to give them too much light.|
