Based on the lumens and the especially the cri the sunlight bulb is better than that daylight. It's also more purplish in color isn't it? At 5000k vs 6700k I would think it would be.

Yea it is.
Purple no, its just a real soft kinda light more like sunset if you will!? I really like it a lot for the overall look of the tank and the fish sure do love it.

Cool. I may have to change my lighting. Or get a mess ton more floating plants. Those 65w pc are bright. Doesn't seem to bother the fish but my Vals I am wondering about. If I change I'll be stuck with a damn expensive light.

I was actually surprised when I took the 4ft daylight out I was expecting some kinda dramatic dimness int he tank...you barley seen any difference others then looking "softer", that did indeed surprise me.

Well now THAT one you can not pin on me ...I sure was NOT the one advising you to buy expensive lights but would have send you to buy exactly the lights I have here from Lowes, Home Depot, Walmart.

What substrate do you have with that high light for the Cory's?
Also as Lisa said Cory's don't do well in new set ups so check your parameters there
And you can "hijack" and ask all you like here that's what we all are here for.
Hmmm... would you recommend I replace the Aqua-Glo, then? I was actually looking at the Life-Glo bulb in the store the other day, which, IIRC, has close to the lumens of the Sun-Glo (~800?), but a temperature of 6700K. So, total of ~1600 lumens?

As for the corys, one had developed pop-eye, so I isolated all of them in a 5g hospital tank for time being until the main tank is stabilized and the ammonia gets down closer to 0. The Zebras and Tetras in the big tank all seem to be doing just fine, but I guess they're a bit hardier...I don't know where I got the idea that the Cory's were a good, hardy starter fish.

Byron, my tank is the standard 55g. Holly is the one with the tall tank.

I have the lights in already (the GE 2x20w Daylight) and I like the look of it. If you think the plants would benefit more from one Daylight at 6500k and one Sunlight at 5000k I can simply exchange one. I did order quite a few "red" plants. I got red wendtii, tiger lotus red, ludwigia repens, anda red rubin (among swords, Vals, pgymy swords, anubias, and they are throwing in some Salvinia for me).

@LMychajluk any light between 5-6500 kelvin and if florescent T8 tube anything that equals 1 watt per gallon or less will do for plants. I pers do not buy any of these Glo series at the pet store simply because they're the same then the mentioned bulbs from Lowes, Home Depot or Walmart but like 4-5 times the price of them.
If you want to just leave it for now and observe your plants if they start looking like melting or poor growth, yellow leaves etc. Then when your bulbs are a year or so old it would be adisable to replace them anyway and then give that a 2nd thought.
You may have to do more then once a week water exchanges until the point where your Ammonia is permanently 0; some people that cycle with fish have to do as much as daily w/c.
Hope your lil Cory there will pull through it!



@Lisa I would leave it with what you got right now. That will be just fine. Thing is in each tank it'll give you a diff look because of the plants in there, the color of gravel etc. So me I just bought 4 diff lights to find the ONE I like best in there lol and played around with it. So if you like play around with it when you have the plants so you'd see the difference and then see what you like. Or leave as it is and when its time to change bulbs in a years time just consider maybe doing the mixture.


On a side note my ludwigia actually looks 'glossier' since I changed lights. Before it was just nomral green -red leaves and now the top of the leaves almost look like wax coated shiny...I think its kinda neat.

I would not use Aqua-Glo. I have one, took it out and here it sits. The light is purplish and very weak (lumens are 1/3 or 1/4 of the Life-Glo as an example). Not in my view a good plant light, plus it makes the tank look goulish.

The Life-Glo is good, one of the best single tubes period, but expensive. You can achieve the same look with less expensive tubes from hardware stores. Get ones that are fullk spectrum (or daylight or enhanced daylight, ultra daylight, whatever they call various ones) with kelvin ratings around 6500K. I explain in part 4 of the sticky series about this.

I agree with Natalie's subsequent response, leave what you have, it is good light.
