C. Helferi
......well, I hope I am wrong and it's something else, but here goes. I have a 75-P ADA's 30"x18"x18" I have a dual bulb T5HO fixture (Coralife Aqualight)....fair reflectors I guess. Anyway, I also have Glosso in the tank and pressurized co2. The Glosso is doing OK, it's growing, but the C. Helferi's leaves are turning brown in spots, starting at the tips mostly. I only have a nitrate test kit, and it reads about 20 ppm. I am dosing a modified EI right now. I dose everything twice a week including CSM+B, P2SO4, KH2PO4, all 1/8tsp. I check the nitrate levels before dosing KNO3 though since the plants were just planted about a week and a half ago. It's not like I can say it's heavily planted because I just planted the plants and the tank hasn't "Filled In" yet. In the tank is the C. Helferi, Glosso, Narrow Leaf Java Fern, and Anubias nana petite. Everything else seems to be growing OK(the glosso is growing a bit in the vertical direction though which makes me suspect a lighting issue.....but I would have expected the Glosso to die before the C. Helferi if the light intensity was the issue. What do you guys think? Thank you in advance for the help.

How long has the Helferi been in the tank?

"C. Helferi's leaves are turning brown in spots, starting at the tips mostly" These plants are grown Emersed, so they take a while to adjust to submerged life.

Lighting is definatly important because they require a lot.

Well, they went into the tank about a week ago.....actually I planted them on the 15th of April. It's been 10 days to be exact. Maybe it just hasn't been long enough? I guess I should expect the same from the Glosso since I did not start them emersed. I would have, but I also ordered the narrow leaf java fern and C. Helferi at the same time and don't have much experience with growing aquatic plants emersed......I figured with all the large plants I ordered, submersed was the way to go.

just posting some pictures of the C. Helferi....I will try to get before and after pictures. It has almost been 2 weeks since first setting up the tank. Here is the progress so far. I am dosing a modified EI. 1/8 tsp of all but KNO3 and that is just primarily because there are sufficient nitrates in the tank right now it's at 20ppm nitrate.

pictures to come shortly.

The Glosso is growing, but I thought it would be lower, this is why I included a picture of the light fixture above the tank. It just looks like it needs to be wider......the C. Helferi better be just getting adjusted to life under water, because it looks like crap :) lol. well not really laughing honestly. Is this just it getting used to submersed life? I hope so.

This is what the C. Helferi looked like 2 weeks ago, just in case you wanted a before and after assessment. And the glosso looked like this 2 weeks ago.

I hate to say this, but that Coralife light is junk. I have it in a 4 x T5HO over a 40B and it just does not put out enough light, especially compared to a Tek light fixture. I wish I did not try to save $100 and went with a Tek.

The reflectors are pretty bad and the distance between bulbs is too close.

cradleoffilthfan 04-28-2012 04:17 PM

I think I am going to place it on Craigslist and buy a different light. Probably going to go with a Catalina light.....I have been talking to him online about a custom light for my tank. We'll see what happens....hopefully my plants survive for just a while longer......the Glosso is doing remarkably well, at least it's growing and green. The C. Helferi on the other hand.....

cradleoffilthfan 05-03-2012 03:29 AM

Just purchased a 30" Catalina fixture.......It will come with 3 24" bulbs......2 switches and 3 HO balasts.......I think the bulbs are 24 watt.......the only thing I was concerned about was the bulbs were going to be a plant gro kind, I think he said 5000K.....Hopefully this works, I was thinking they might have the 6700K but I guess not....I might just have to buy different bulbs later, but at least the 24" bulbs I can find around here are ok....not like my Coralife fixture, you pretty much have to buy the bulbs from them because of the specific size.

how exactly are you diffusing the co2? i dont think that lights are your main problem.

cradleoffilthfan 05-03-2012 03:44 AM

co2 is being diffused by an inline GLA diffuser. This one actually

cradleoffilthfan 05-03-2012 03:46 AM

also have a GLA double drop checker. Co2 indicator is at yellow. No fish or inverts. Just plants at the moment.
