Besides cutting them off because I want to encourage the plant to be bushier I've always thought that the lilypads floating on the surface will block light out for the other plants. Ok, off to google the flower to see if it's worth it to stop cutting off the lilypads.
Trimming it back will increase bushiness. To me it's really a trade off - up or out. ;) I think the flowers are lovely! But we do different tastes in plants. *lol*

*more research* Seems the best way to trigger Lotus blooms is going open-top. This would rule out all the florescent fixtures I've found; they were ugly anyhow. *heh*

Would 24W HO T5 at 6700k be weak enough to discourage the cyano? Specifically the 24" Hagen Life-Glo. They make an attractive water resistant single-bulb fixture that I'm checking out.

I'm hoping the extra few watts are ok since I have a sprinkled layer of duckweed and lily pads going on in there. Cause it seems (so far) that is as dim as it gets while going open-top. I double-checked the LEDs; they too require a canopy.

Yep, no open top for me, I have some serious jumpers. So for now I'll opt for bushiness.
I'd think you'd be fine doing 24W at 6700K and it should diminish the cyano. My lighting system prior was CFL 6700K at 130 watts. Stepping down those few watts and going T8 really helped my situation, I also added Purigen to my filter. So it's hard to say it was one or the other, or both combined. Either way it's all good now.
I'm convinced it was your massive wattage that was the culprit here.

Just picking up on a couple of questions/issues since I last posted.

Spectrum is as important if not moreso than intensity. Red-leaf plants need more red light than green-leaf plants. The colour of the leaves is due to the light colour that is being reflected off the leaf. This is one reason why plants do not need green light, only red and blue--they reflect green. In the case of red-leaf plants, more intense light is needed to compensate, otherwise the leaf will tend to be less red and more olive green/red or brownish/red, depending upon plant species. Having blue-heightened lights over the tank as you have is not going to help a red-leaf plant. And therefore, providing the proper spectrum will allow you to reduce the intensity.

Watts per gallon really means little as there are so many factors plus the type of light--T8 for instance is more intense than T12 in identical sized tubes of identical spectrum and identical watts. And some manufacturers make tubes with more intensity and less wattage (to save energy), so a 32w can be equal to a 40w of the same spectrum/type.

As for red tiger lotus, I have this plant in my 29g and 33g tanks (one in each) under one Life-Glo tube (6700K). The 29g tube is 20w, the 33g is 25w, and the plants are growing fine for me though I know I could increase the light and get brighter red. Flowering in an aquarium is, according to Kasselmann, very rare. And the flowers only open at night (in darkness).

There is a balance in all this. Light must be adequate in spectrum and intensity to begin with, and then nutrients must be in balance with that. If anything is missing, the plants will slow their growth, and in extreme cases may die off. You big issue is the light, as I think I have explained, but if not please ask and I will elaborate.

Second though is the lack of nutrients. Without adding fertilizers the plants are struggling. They cannot make use of the light, which is why algae and/or cyanobacteria appears. These organisms do not care about the type of light. Algae will flourish in very blue light, in which plants would not even last [I'm talking total blue, just to be clear]. In mixed light that is not balanced, plants can make use of it and algae/cyano will. You obviously have high organics from the fish, fish food, source water--otherwise cyano would not be so bad. But something is bound to be missing. Plants need 17 nutrients, and while some occur in tap water (if it is hard), some in fish foods, and some from organics (decomposing waste, etc), some are certain to be missing.

Thank you both again for all this amazing information! Earlier today I placed the order for the Hagen single HO T5 strip and a Life-Glo bulb. So we are on track for lights. :D

I also ordered some Purigen and The Bag (gotta love the 'original' name *sarcasm*). A lil pricey, but after aunt kymmie's mention I researched the *bleep* of out this stuff and it sounds very worthwhile.

Looks like I also need the Purigen for my new reef tank; my reef-expert friend confirmed today that what I'm seeing in there is also cyano. The lighting on that tank is appropriate for my long term plans, so I gotta attack it from another angle. Luckily my clean up crew in there is eating the stuff, just not quite fast enough. :)

I don't want to change too many things at once. So I'm not going to use ferts immediately. But I'd still greatly appreciate your advice on which type/brand is good for my given situation. My plants are in 'black beauty' gravel; which I vacuum with each water change. I only use Prime with water changes. :)

I have all my tanks lights on from 1pm-8pm 7 hrs all on a timer from Home Depot. 12 hours of light is alot of light.

Yes, it's a little pricey but well worth it, IMO. It lasts six months, can be "recharged" by cleaning it in a bleach soak. I don't plan on recharging mine, I will just replace it. 1077 turned me onto using it, he used it in his discus tank, and so far I'm really impressed with the results. I think you will be too!

I know Eileen mentioned she only has her lights on from 1 to 8pm (seven hours total) and if you are keeping low light plants that's not a problem. I'm not sure of Eileen's plant list.
If I did any less than my lighting schedule (timers-on at 10am and off at 9pm) I know my particular plants would suffer. You and I keep alot of the same plants in our tanks so I think somewhere in the 10 to 11 hour range is good. Congrats on getting new lights, I know you and your tank are going to be happy with this change!!

Seachem's Flourish Comprehensive Supplement is the best I've found. You use very little so the initial cost long-term is actually much less than other brands, which are not all as good anyway.

Most of us with planted tanks rarely if ever vacuum the substrate; you will remove organics the plants can use. There is a host of bacteria living in a healthy substrate. Let nature do its thing.

No vacuuming, eh? Good to know!

Do you also use/recommend Flourish Excel? I don't do CO2 injection because I want to keep a simple setup. The idea of carbon in a liquid form is intriguing!

Got the new light and Purigen in place. Looks great so far!! :)
