Java moss and java fern help
Hello everyone,
At the risk of giving too much information, I've included all my aquarium specs at the top. Feel free to skip all of this info and head straight to the question below My Aquarium: - 10 gallons - 3 months old - Lighting: 14W - Temperatu 76F - Fertilizer: None - Substrate: Play sand - Salt: None - Additional C02: None - Ammonia: 0 - Nitrites: 0 - Nitrates: ?? (don't have a test kit for it) My Fish: 2 adult platys 1 two-month old platy 3 one-month old platys unknown number of newborn platys 1 oto My Plants: Java Moss Java Fern Hygro polysperma Hygro "Siamensis" Hornwort Anubias (I think nana) Small amount of bacopa Cladophora algae ball --------------- Okay, now to the actual main part of my message For the most part, all my plants are doing very well. My hornwort grows so fast that I need to remove 1/3 - 1/2 of it every other week. My Hygro "Siamensis" has had to be pruned to half it's height twice now. Strangely enough, the plants I'm having the most trouble with right now are the supposed "idiot proof" plants: Java fern and java moss. Some leaves on my java fern are slowly turning brownish/black. I'm not sure if it's the plant itself or if it's some type of algae on the plant that is causing the discolouration. I have taken a picture of the most severely affected leaf, though it looked slightly prior to this picture being taken as I tried to scrape off some of the discolouration with my finger nails: http://members.shaw.ca/oople/fish/java_fern.jpg Any ideas what is causing the problem, or how I can prevent it from spreading? The second problem is that my java moss seems to actually be dying off! When I first bought it 3 months ago with was a nice deep forest green colour. Now, I'd say about half of the strands have turned brown. Currently, I have a bunch of it tied down with thread to a clay pot / cave. I have a few pics of it so you can see what's happening http://members.shaw.ca/oople/fish/java_moss_1.jpg http://members.shaw.ca/oople/fish/java_moss_2.jpg http://members.shaw.ca/oople/fish/ja...2._closeup.jpg Again, does anyone know the cause of the problem? Is there a way to salvage it without having to buy a new batch and pray that it lives this time? I wasn't really clear on how to die it down properly, so perhaps I just have too much bunched together? One final question. I currently am not using any fertilizer, but with so many plants in my aquarium, I'm thinking that I'm probably running low on nutrients for them. What's a recommended fertilizer for a low light set up with no additional C02? Not that my oto would complain about an algae bloom Thanks in advance! -- April |

Java moss and java fern help
Strangely enough, the plants I'm having the most trouble with right now are
the supposed "idiot proof" plants: Java fern and java moss. Some leaves on my java fern are slowly turning brownish/black. I'm not sure if it's the plant itself or if it's some type of algae on the plant that is causing the discolouration. I have taken a picture of the most severely affected leaf, though it looked slightly prior to this picture being taken as I tried to scrape off some of the discolouration with my finger nails: Welcome to the "Better Idiots Club", open to all who can kill java fern and java moss. I'm in the same situation, and posted a similar message yesterday (the photo of my afflicted Java fern is he http://web.mit.edu/lovell/www/aquaria/java.htm I did a search on google groups and found numerous past postings on this condition, so don't worry, we belong to a big club. Anyway, i haven't yet found a posting that is convincing as to the cause, but most agree that removing all the affected leaves - even slightly affected leaves - will stop further loss. That may mean going back to the rhizome, but at least you'll save the plant. So far the explanations for the cause have been: 1- An infestation of blue-green algae (cyanobacteria) that stunt the growth of the plants in the tank and promote this problem with the java fern 2- A sudden change in conditions leading to a condition similar to "cryp melt", but for the java fern. In my case, the light was left off for several days over Thanksgiving while i was out of town. In other cases, addition of a new carbon filter or even a water change have been blamed. 3- A lack of macro- or micronutrients. Note that none of these are mutually exclusive. I DID notice a lot of patches of blue-green 'algae' around the time problems began, and i began adding fertlizer not long before the incident, so perhaps i adjusted the deficiency to one that promotes the java fern melt. My java moss is browning now, just like yours, but it was previously growing like a weed. I think the culprit is me - i was spooked by the ill effects that adding fertilizer seemed to have had on the java fern, so i stopped adding it. I'd suggest you add some fertilizer and see if your moss recovers. I'm sure more experienced keepers are cringing, but right now i'm just using some Schultz liquid fertilizer, adding a few drops each time i change water or each week. One final question. I currently am not using any fertilizer, but with so many plants in my aquarium, I'm thinking that I'm probably running low on nutrients for them. What's a recommended fertilizer for a low light set up with no additional C02? Not that my oto would complain about an algae bloom Did you read about making your own PMDD? That's what i'm going to do when i get the ingredients i ordered. Good luck. Please contact me if you find more conclusive information than what i shared here. |

Java moss and java fern help
I tend to find that higher light can hurt java ferns...a 10 gallon is really only
about 9" water with substrate, so 14 w is actually a decent amount of light.

Java moss and java fern help
"LeighMo" wrote in message ... That is probably your problem. IME, when nutrients are low, it's the java fern and java moss that suffer. They can't compete with the faster-growing plants for limited nutrients. Tropica Mastergrow is a nice, complete fertilizer. If you can't find that, get Seachem Flourish. Thanks, that makes perfect sense. I'll run out and get some as soon as I can! -- April |

"Flandry" wrote in message om... Welcome to the "Better Idiots Club", open to all who can kill java fern and java moss. I'm in the same situation, and posted a similar message yesterday (the photo of my afflicted Java fern is he http://web.mit.edu/lovell/www/aquaria/java.htm Ohhhh, does membership come with a free t-shirt or a secret handshake? Though I must say, your java fern looks in far worse shape than mine! Yikes! I hope it recovers fully for you. I did a search on google groups and found numerous past postings on this condition, so don't worry, we belong to a big club. Anyway, i haven't yet found a posting that is convincing as to the cause, but most agree that removing all the affected leaves - even slightly affected leaves - will stop further loss. That may mean going back to the rhizome, but at least you'll save the plant. Argh, I didn't want to do that, but I guess I'll have to. It is such a nicely shaped plant at the moment. Oh well, so goes life. snipped some great possible reasons for the cause I'd suggest you add some fertilizer and see if your moss recovers. I'm sure more experienced keepers are cringing, but right now i'm just using some Schultz liquid fertilizer, adding a few drops each time i change water or each week. I think I'm going to try to find the Tropica Mastergrow that Leigh suggested and start adding that. I must say, it's a rare and pleasurable experience on a newsgroup to see multiple people recommended the same thing (i.e. adding fertilizer). Did you read about making your own PMDD? That's what i'm going to do when i get the ingredients i ordered. I've read that many people here use PMDD, but I think I'm too lazy to go through all the work of making it just for a 10 gallon aquarium. A store bought bottle of fertilizer would probably last me forever anyways, but thanks for the suggestion anyways. Good luck. Please contact me if you find more conclusive information than what i shared here. Will do! Thanks for all the help! -- April |
