Is this considered high light?

[Mikeybabs]

Lighting: 24" 2x24W Miro-4 T5 High-Output Retrofit Kit w/ Bulbs

55 gallon standard

2" seachems black fluorite sand

Driftwood and rock decorated

How many hours should I leave the lights on? Right now it's on 8hrs a day with 4on/off/on/off and seems to be doing ok

Do I need to worry about co2 or excel?

Tank is IMO heavily planted but maybe moderately stocked.

Thanks everyone!


Any guidance is appreciated. I've only been into planted tanks for about 2 weeks now and still learning

I am not sure if you have a single retro kit, with the 2 bulbs in a line to form basically 1 single line of light or if you have 2 retro kits and 2 lines of lights over the tank.

If it is 1 line, you're good. If it is 2 lines, you have very high lights and will need CO2 and a fertilization plan and high light/high growth plants.

your tank looks good. On here, most would say it is lightly planted. You have mostly slow growers, crypts and anubias. With these, you need to stay in low/med light. They will benefit from periodic ferts or root tabs (no need for daily dosing) and always love CO2/Excel but will be fine without it.

set your light schedule to when you want to view the tank and stay at 8 hrs.

Hi,

My only concern with your light timing is the 4 hr on/off periods. IMO (with no scientific evidence to back it up) is that the plants MAY not process optimally with a daily 4 hr interruption of the assimilation/light cycle.

I realize that nature gets cloudy, rain, etc but the sun doesn't go OUT daily for 4 hours....

Your tank looks nice but you may want a few more plants. I would not consider your scape heavily planted.

thanks so much for your input. it is a single line of bulbs, so would you say its medium light then? i think im going to add some fast growing plants to the mix to make things more interesting, do you have any recommendations? How about water wisteria? can you suggest a dosing plan for the ferts and excel? i want minimal ammount of work! right now the lights are set for 8 hours a day and on during the times im viewing the tank... on my days off can i increase the viewing time from 8hrs to 12 hours or is that bad? im only off 2 days a week... any names of nice looking fast growing plants would be great... thanks a lot!

hmm i have read on other forums that people have had success with the 4on/off/on schedule and people actually switch to it to reduce algae? you might be right though as i can't back anything up with scientific evidence... in fact if i had a choice i would choose to do 8 consecutive hours every day, however the problem is i work from 2:30-11pm every day, 2nd shift, meaning i like to view them for 4 hours before i go into work, then 4 hours when i get out of work, so the schedule is 10:15-2:15pm, and 9:15-1:15am... if i did 8 consecutive hours starting before i went into work then i would be missing them all day long and they would be off when i get home thanks for your input though! now that you said that about not being heavily planted i would have to agree and i think i should add some fast growing plants to the mix... thank you!

Hi,

I would regard yours as a low light tank, which is great if you wish to stay away from CO2 and such. I keep tanks with little or no lighting beyond the ambient light (we have lots of that here).

I agree with Gerry I would add a few more plants, dose on the light side with the fertz.

Hmmm if you already had decided other forums had the “right” answer (the one you wanted) why bother asking the question here?

Gerry gave you an honest answer based on his experience and understanding.

Personally I agree with him, I am aware there are some, particularly those that like very high lighting claim “siesta” times allow the higher light without algae. Okay if that is there experience, fine.

I agree with Gerry I just do not think that "siesta" times provide optimum situation for the plants, particularly at lower light levels.

Hello. Thank you for your reply. I didn't say the other forums had the right answer I was just stating what I read on other forums to be a possible answer. I was questioning this on this plant forum because I felt like I would get a more accurate answer...

So you guys think it's bad to do the 4 on/off/on schedule?

Also I was told by the person selling my lights that they would grow almost any plant and they are moderate to high lighting and not to pay a huge deal of attention to the WPG rule. He said the reflectors make them intense or something like that. Me being a newbie doesnt really know who to listen to lol

If they are low lighting I will be happy because I don't want co2 and i just want to dose lightly on the ferts.

Since you said dose lightly is there a specific guide or amount you can direct me to?

I plan on adding more plants soon... What is a siesta time?

Thanks everyone for helping out a newbie

BTW, when cloudy condition exist, the PAR is still around 500-1200mmol.......or a LOT of light..........as Gerry stated, the sun does not go out for a few hours, this is not in the middle of the day, it is much more typical late in the afternoon/evening.

I think many folks that honestly do not know and do not KNOW me or Gerry from Adam....so they are going to ask....the web loses some of the innocence we all have when we are new to all this. It can come across wrong, believe me......folks think I am very different on line that when they meet me in person. I come across harsh on line. Who's to say who's right?

Well, you can convince the honest folks. Be straight with them. The others? Nope. No convincing the faithful believer.
A siesta will not hurt a tank.....but I've never once been able to show it helps a tank either.........That darn P. Hiscock put it in a book and everyone thinks it is some "real solution".
There is no support for it.

There are many examples where the treatment neither helps, but importantly, does not harm the tank etc.........so a few folks will get some correlation and their tank improves, but others try it and find no impact.
You can try this several times also. This is not a bad treatment to test, it cost no money!

So you are not out anything, but you gain nothing also.
It's more a marketing thing that appeals to wishful thinking and sounds somewhat reasonable till you realize how much light is still coming down and into the water even on a very cloudy day.

Thank you for replying! Since you say it has no negative impact then I will continue to do the 4 on/off/on routine.... The only reason I'm doing it is because it fits in with my work schedule better. Otherwise I would continue to do 8hrs in a row everyday cuz it feels more natural but I don't know the science behind it and am open to honest explanations

Thx everyone for supporting my newbism

Hi,

BTW, I think that 48 watts of t5ho on a 55 gal IS high light and this may cause issues going forward. As far as a 'siesta' this is simply a rest period for the plants as they will 'shut down' when the lights are off for 4 hours. My concern is that the plants now need to wake up twice daily.

If the plants remain healthy then no reason to change. I think the high light will cause issue going forward. Planting much more heavily will help somewhat. However, light is what drives nutrient demand for c02 and macro/micro ferts.

Since you don't have c02 this could be a problem with the high light.

What about using only 1 bulb and leaving as is?
