DiverJohn Posted January 11, 2005 Report Share Posted January 11, 2005 Hey Peoples , last week in another post Warren identified one of my plants as Rose Amazon Sword (Echinodorus osiris). I am not exactly sure but I dont think it is doing too well. When i bought the plants they looked health with nice long stems and good looking leaves. These died off after a couple of weeks so I pruned back quite hard and left them in to see what developed. Slowly leaves have developed, but they just dont look healthy. Black veins on the leaves... http://img.photobucket.com/albums/v626/DiverJohn/Sword001.jpg And then they seem to get holy and die off... http://img.photobucket.com/albums/v626/DiverJohn/Sword002.jpg These plants are quite low in a tank 500mm deep - 1.1x.5x.5 approx 250l. Lights are on 11 hours a day, 4x30W (3footers). DIY CO2, and a JBL 7 Balls close to each one. 5 ml of floursh exel evry 2nd day. Blue Hygro, Cambomba growing well, Japonise Rush growng "OK". pH 7, evrything else 0, gh 4. Any suggestions - could the Hygro and Cambomba be stripping the water of a trace element?

Plantman Posted January 11, 2005 Report Share Posted January 11, 2005 brother, from your description, i believe you have done well for your plant. i may suggest you double your dose of DIY CO2 into your tank. thats what i did and my tank plant is growing again. you can triple dose but your must check you Ph (prefer 6.8 - 7)and Kh (3-4). cheers Quote Link to comment Share on other sites More sharing options...
spooky Posted January 11, 2005 Report Share Posted January 11, 2005 I had a normal amazon sword which started having problems despite everything else in the tank growing well. The ends of the leaves fell off and I was about to pull it out. Instead I moved it into a clear area in the middle of the tank and out from under the Hygrophilia Diformis which had grown up around it. As a result it has sprouted three new leaves in the past week (after a couple of months of being dormant). My guess is the better light, and less competition from its neighbours helped. OK, so it's not exactly the same plant and not exactly the same problem, but I thought I'd share anyway . Quote Link to comment Share on other sites More sharing options...
Warren Posted January 13, 2005 Report Share Posted January 13, 2005 Looks like you are low in iron. Echinodorus osiris should have fairly red new leaves which fade to a green/red when fully grown. The veins should be dark but the rest of the leaf quite red to start with. Add iron tablets to the substrate as this plant is predominantly a root feeder. Do you have Bristlenose? If so, this could be causing the damage to the leaves. Osiris has a very delicate membrane that Bristlenose damage easily... Quote Link to comment Share on other sites More sharing options...
DiverJohn Posted January 13, 2005 Author Report Share Posted January 13, 2005 Could be right on both counts Warren. Tested Fe last night (dupla test) was 0.1 is that OK? Should I bump it up a bit? This plant also has a JBL 7 Balls under it. Also I have started another small tank for plants and purchased a box of Laterite. LFS chap suggested adding a small amount around my plants in the big tank as a "general" fertilisation regime. Did that last week. Earlier this week I also added another 30W tube (5 in total 8) ) Last couple of days I have noticed there is some new growth coming out that is a distinct red/brown colour. And yes I do have bristlenoses and a plec, they might have to go. Thanks for your help. Quote Link to comment Share on other sites More sharing options...
Warren Posted January 13, 2005 Report Share Posted January 13, 2005 0.1 is ok. Do you add trace elements? Replace bristlenose and plec with SAE's Quote Link to comment Share on other sites More sharing options...

DiverJohn Posted January 14, 2005 Author Report Share Posted January 14, 2005 Hey Warren, is this looking any better?? ( And playing round with the camera :lol: ) Quote Link to comment Share on other sites More sharing options...
Warren Posted January 14, 2005 Report Share Posted January 14, 2005 Cool 8) However, now that I see a better photo of the plant, I don't think it's an osiris. I don't know what it is. Anyone else?... Quote Link to comment Share on other sites More sharing options...
cees Posted January 14, 2005 Report Share Posted January 14, 2005 I used to have that one. Always thought it was Echinodorus bleheri ?? http://www.tropica.dk/productcard_1.asp?id=071 New leaves are red-ish. Leaves on stalks. Quote Link to comment Share on other sites More sharing options...

DiverJohn Posted January 16, 2005 Author Report Share Posted January 16, 2005 Thanks Cees. Will post the occasional pic and as it progresses. I really do wish the LFS would name the plants properly Quote Link to comment Share on other sites More sharing options...
