buildmyled 24" iwagumi 7000k and glosso


Hi,

I ordered the buildmyled.com iwagumi 7000k 24" led: http://www.buildmyled.com/iwagumi-7000k/

I have a 24"x12"16"(height) tank with 2" substrate -> 14" height from substrate to top of tank.

I am doing pressurized co2 and full nutrient dosing.

I want to have enough light to grow glossostigma but not too much to become an algae factory. What should I set my buildmyled dimmer to? (ie 100%, 70%, or?)

Thank you

Glosso can grow well in lower lighting levels, easily.

If you want it to carpet and crawl low to the substrate, shouldn't you run it high and just crank up the co2? If you start seeing algae, you can dial down with the dimmer or reduce the photoperiod.

I've heard the guys over at BML are pretty good at answering these questions.. they have a forum on their site?

Or... you can always buy a Hoppy DIY PAR meter to get an estimate

so my led finally shipped and will be here next monday, i am very nervous about it being too powerful and turn my tank into an even bigger algae farm.

My plan per above is to get some glosso as i understand they are fast growing nutrient absorbers, to keep the algae in check. Will that be good enough? anything else i can do to make sure the highlight doesnt cause algae problems?

one of the biggest problem even now is i notice algae growing on the aquarium glass, not sure how to prevent that.

remember, balance is key. manual removal, a clean up crew and chemicals will only stall the problem. find out what is unbalanced in your tank and research the kind of algae you have ASAP. balance balance balance

You can get a dimmer for the light if you need it.

Yep. I'm running the 6300 dutch with dimmer now. I ran it at 50% light until I got my EI ferts and co2 system.

I'm growing glosso now with co2 injection and the 6300 at 100%. It's starting to throw off runners in only a week or so.

With high light you need good CO2, especially CO2 that stays at the same concentration every day when the lights are on. Without that, algae is almost sure to follow. It isn't a problem of excess nutrients, it is a problem of plants not growing in good health at the rate the light is driving them to, and that means you need plenty of CO2 so they can do that, plus consistent CO2 because fluctuations tend to trigger algae to start growing. You also need very good tank maintenance, keeping everything clean, keeping any starting algae immediately removed or killed, etc.

Thanks guys i have ordered my glosso which should come a day or 2 after the light.

Hoppy, co2 wont be a problem i have no livestock in the tank right now so i can crank it up as much as i want, and it's getting diffused through my tunze powerfilter so almost 100% diffusion. I turn it on 2 hours before the light comes on and turn it off 10 mins after light turns off.

Hi bsantucci, do you notice any algae after going 100%? what's the height of your light to the substrate. Looks like i will be following your foot steps doing exactly the same! thanks

Honestly I have only had it up for a week like that but I don't have any algae issues yet. Not sure how long it will take to show up if it will.

I have a 20 high tank with about 2 inches substrate so roughly 18 inches.

I need to trim the glosso already though cause the week with 50 % lighting made it grow up instead of carpeting. I'll use the extra growth to fill the carpet in though.

hiya,

ive always kept glosso and find that high light and some co2 will encourage it to stay rather low, round leafed and spread more horizontal. Those who have glosso growing up past an inch probably dont have enough light where the plant is reaching upwards.

I'd increase the light intensity or duration (not both) to determine which works best.

i have a buildmyled and i keep it at 50% to keep algae in check.
i have dhg and s.repens in my tank. s. repens grows pretty slowly in my tank.

aquasoil/ei dosing/pressurized co2 is used on my tank. the fixture is pretty high light imo. i'm using a 36 inch fixture

Here it is, all ready! day1

I didnt notice the buildmyled to be high light even at only 14" from substrate, i had it running for a few days before the glosso got here and algae wasn't that bad. Also the dhg, dwarf sags, and other plants in my tank didnt grow either after i replaced the current-usa led+ with buildmyled.

So leaving it at 100%. I hope it's enough light for the glosso!!
