Re: Aquarium lighting

Hello fish lovers.I feel has though I have come to the right place with my question! I have rejoint after 40years working.
I have been using daylight for lighting my 40x40x65cm tanks Cold & Warm. even though we receive lots of sunshine here in southern Spain the plants do not look happy after one year. I have now installed a LED lighting tube. How many hours should I have the tank light on ? 10 watts 6500k. which is very bright.

Re: Aquarium lighting

Really depends on what kinds of plants. My planted has micro swords dhg and various other swords my lighting is on 6 to 7 hours a day at 3 watts per gallon. And I am using a DIY CO2 not sure what the math is on led lighting or what size tank

Re: Aquarium lighting

I would start with 6-8hrs, see how the plants respond, and adjust from there.

Re: Aquarium lighting

A lot of the lighting terminology is way beyond my understanding, but based on the info above, couldn't I build an led light using a string of red LEDs, a string of blue LEDs, and a string of white (to increase visibility)? It seems like that would work, since plants like the ble and red ends of the spectrum, and we see things well in white light. Am I missing something, or would it be worth a try?

I doubt it's worth a try. I have TMC Grobeams in my tank and they are exceptionally well designed. Compared to loose LEDs, they're drawing about 3W per LED and all are 6500k. They are also very directional so while they are putting out 80 lumens per watt, it's more like 140 lumens of T5 equivalent because no reflector can come close to the directionality of a LED with it's lenses.

LEDs can give you the right spectrum, direct all the light in the right direction and be more efficient at the same time. I have 24W on a 15g running for 4-5 hours per day and won't need to change a bulb in over 5 years.

There is a downside though - they require very good ventilation to operate for these long periods so ideally, not in a hood.

Re: Aquarium lighting

I have a relatively new tank with plants and not too many fish. I have been pretty overwhelmed with algae, despite a couple of otocinclus and an aggressive water replenishment routine. I have a 29 gallon tank and have been replacing about six plus gallons a day of water to help keep the nutrients down. I have eco complete as a substrate. Is their a happy medium between amount of light for needed for some relatively easy plants and not growing a great algae crop? Not that I don't like green but.......

Re: Aquarium lighting

Pete,
algae is a sign of an imbalance between Light, CO2 and nutrients.
Of the 3, CO2 is the only one that too much of doesn't cause algae - so long as the CO2 levels are high and stable.
So... you're limited by CO2 and need to light/feed accordingly.
You can turn off some of the lights, decrease the photoperiod, add CO2 or do all of the above.
An alternative is to use Seachem Excel in the tank which will increase bioavailable carbon allowing the plants to beat the algae.
Or you can do all 4.

Re: Aquarium lighting

I appreciate the quick reply. I am not currently adding CO2 to the tank. And frankly because I am still new to this was not quite ready to go there yet.

Anyway the ph tends to run low (6.2 or so) and my understanding is adding C02 to the tank might drag it down even further. I had the lights on 12 hours a day and already reduced it to 8 hours. I am enthusiastic about having plants and am afraid if I cut back on light too much the plants will suffer.

I will try the Seachem. At least the fish seem happy in their green little world.

Thanks very much.

Re: Aquarium lighting

Pete, are you running the grobeams?
I'm running mine for 6 hours at a time.
My tank is about half the size of yours so double what I'm doing and you should be OK.
I'm running a soda bottle reactor into a 200l/hour $10 filter and dispersing the bubbles across the tank. If you run 2 of these (2 cups sugar 1 tsp yeast) you should get good CO2 dispersal.
Excel and reduced light will likely save you though. At one stage I was running 4 hrs as those grobeams are intense!

Re: Aquarium lighting

Yes I am using those lights. I made a hood and mounted them. I like the quality of the light.
Thanks again for the advice. I will let you know what happens.

Re: Aquarium lighting

I have a 29 gallon (~30 inches Wide) that I am looking currently try to buy new lights for. I was looking for a dual T5 HO system. From what I have seen, most of the "higher reviewed" items are 48 inches long. I'm guessing that the lights for this are either 28" or 24" as those seem to be the common sizes for bulbs. Any ideas or recommendations? I am planning on having a medium planted community tank.

Re: Aquarium lighting

I would have to say I really like the quality of the LED lights and certainly they are cheaper to run, but at more cost initially. I keep them on about 7 hours a day. In the beginning I had a terrible algae problem, but with time that seems to have cleared up as the plants became established. Perhaps the Seacham helped. To be honest I was thinking the plants and substrate were a bad idea.....but after a couple of months every thing has settled down and the tank turned out really pretty. The advice on this site was very helpful. Without it I might have ended up with a sterile looking tank with a gold fishautolinker.com autolinking image or something. Thank you everyone.

Re: Aquarium lighting

I also like the idea of LED's. In a ~29 gallon tank, do you need to have more than one set? I have seen them in a "pod" shape and also in strips. There are so many types of LED's I'm not sure which get. I've seen some with red, blue, green and white strips as well. I understand the purpose of the colors but are they necessary? Why are some colored and why are some more blue/white? Is is just for those people looking to feed plants with different spectrum needs? OR is the coloration more gimmick??

Re: Aquarium lighting

Water depth plays a big part in how much light the plants need. The LPS by me that I rate a 9 on a 1-10 scale is owned/operated by an ex school biology
teacher. He regularly points out that all his 55 gallon tanks have regular T8 lights on them and the plants do just fine. But he is referring to the two bulb
shop light type fixtures and not which kind of bulbs he uses. I'll check on that the next time I'm there.
For a 55 I would start/w one Zoo Med Flora Sun max plant growth bulb and one 10,000K.
I have the T8 (but on a ten gal) and I like those because the fixtures are one bulb. They can be on separate timers that way. I have one (a Zoo Med Flora grow)
on from 9A till 6P in summer. The other bulb is a Zoo Med Ultra Sun 6500K and it is on from 11A till 3P in the summer. You likely would not think that two of
the Zoo Med Flora Grow bulbs are enough visible light for your viewing the tank. An option for a less expensive one is the Aqueon Full Spectrum (8000K) but
it has substantially less light(visible) than the 10,000K but may be a suitable alternative to the ZM Flora Grow as it advertises it has good plant light.
With two bulbs in a T5 set you will need to limit your light to 7 hrs to keep down the algae. Really any two bulb fixture because you can't regulate each bulb.
BTW: I don't remember where, likely in a review of a bulb, but I read recently that a person said he had tried the 10,000K (it was a T5 and I presume it
was a two bulb set) and found that he got better plant growth/w the 6700K bulbs. As far as I know only Coral Life Nutra Grow comes in 6700K in a T8.
Have never tried one of those as "if it works then don't mess/w it" is keeping me buying the ZM Flora Grow 6500K. My "other bulb" changes from time to
time but that one stays.

Re: Aquarium lighting

Ok so I have a question. I have a 10G lightly planted, mostly anacharis. I have a 18" 15w zoomed ultrasun. I found a aerogarden in my basement and have gotten the light from that to sit above the tank. The light says it is a aerogarden grow bulb rated at 26w. But the thing is on this new bulb I looked up the kelvin rating and its only around 4000-5000k. I know the 6500k of the ultrasun is better but the aerogarden one puts out more watts. I just put the aerogarden one on this morning but which do you guys think would be better?

Re: Aquarium lighting

Watts can be deceptive as some bulbs put out more for less so to speak. The K rating say's that the aerogarden is less than what we normally
would use on most tanks but on a ten which is only about ten inches from top to the top of the substrate, that may be enough.
I'm curious as to why you wouldn't use both of them as I have two 18" x 15W bulbs on my ten's. I used to use that ultra sun as one/w a zoomed flora grow
as the other bulb on each tank but now I am experimenting/w different ones on each. Just curiosity to see which combination works best on the plants.
A caution though. This level of light causes algae a bit more than just one bulb.

Re: Aquarium lighting

Yeah well the aerogarden one takes up a big top of the tank. I have a florasun bulb as well. I might try to have both the florasun and the ultrasun. I also have diy co2 and dose with seachem comprehensive

Re: Aquarium lighting

The more blue the lighting is, the more useable light actually gets to the plant or coral. The reds scatter almost immediately when they enter the water surface.

Not totally accurate
10k is a blue light

22k is Blue straight up.
The 420nm lighting is more in the purpleish range
