chernyi Posted June 25, 2016 Report Share Posted June 25, 2016 Like the title says, my pogostemon helferi is dying off one by one starting from the right and now working on to the left, so far 6 out of 11 have died off and the single one on the right is fine. The other ones are healthy and green. All other plants are fine and my temp is at 30. One dies every week or so. Anyone experienced such things before? Its like they are slowly picked off one by one and nothing is there to bother them (eat them). Could it be that my PSB bacteria is eating them?

jem_xxiii Posted June 28, 2016 Report Share Posted June 28, 2016 If I remember correctly they love CO2. How's the CO2 situation going in your tank? Quote Link to comment Share on other sites More sharing options...
Shrimp Life Posted June 28, 2016 Report Share Posted June 28, 2016 what type of substrate are you using... and lighting? Quote Link to comment Share on other sites More sharing options...
Pescador Posted June 28, 2016 Report Share Posted June 28, 2016 As JEM_XXIII has mentioned it likes CO2, it also likes a nutrient rich substrate, ferts especially micro nutrients in the water column and needs fairly strong light to maintain compact growth. It is a very beautiful plant but because of its requirements above can be a challenge in a shrimp tank. My guess in your situation is that the plants are using up the available nutrients, then slowly dying off. Your substrate is providing enough short term but not enough to keep the plant healthy long term. Quote Link to comment Share on other sites More sharing options...
chernyi Posted June 29, 2016 Author Report Share Posted June 29, 2016 Update: The other 5 are now doing fine but the symptom has passed to another plant Alternanthera reineckii (rosaefolia) to the left of the tank and overnight 70% of the plant are dying from root to the top. The top 30% looks fine (very healthy) and the other looks melted. Just before I slept it looks healthy and fine. I'm using T5 lighting with a green (healthy) indication for my co2. Substrate is ADA amazonia. Quote Link to comment Share on other sites More sharing options...
Fishprinceofca Posted June 30, 2016 Report Share Posted June 30, 2016 Curious. Sounds like something might be affecting the roots, which would diminish the plant's ability to absorb nutrients from the substrate. My Pogostemon helferi died similarly until I switched to higher lighting. How big is your tank, and what are the dimensions of it and your light fixture?

chernyi Posted June 30, 2016 Author Report Share Posted June 30, 2016 My tank is 45*29*35 and the light is 2x45cm T5 tubes 16 watts each running at 12 hours a day. Quote Link to comment Share on other sites More sharing options...
chernyi Posted June 30, 2016 Author Report Share Posted June 30, 2016 Sorry I cant take a pic right now but this is from some time ago before i switch to a lighting with more intensity. Quote Link to comment Share on other sites More sharing options...
jem_xxiii Posted June 30, 2016 Report Share Posted June 30, 2016 Is your downoi being grown from tissue culture? Quote Link to comment Share on other sites More sharing options...
chernyi Posted June 30, 2016 Author Report Share Posted June 30, 2016 Yes it is! Quote Link to comment Share on other sites More sharing options...
jem_xxiii Posted June 30, 2016 Report Share Posted June 30, 2016 Well I think I may of solved part of the problem. Tissue culture plants tend to take a while to adjust to being submerged. I had absolutely no luck growing downoi via tissue culture. So the CO2 situation in your tank is...? Mr. F 1 Quote Link to comment Share on other sites More sharing options...
chernyi Posted July 1, 2016 Author Report Share Posted July 1, 2016 I don't really know, I use a permanent indicator to tell me if its healthy levels or too much. Quote Link to comment Share on other sites More sharing options...
jem_xxiii Posted July 1, 2016 Report Share Posted July 1, 2016 How are you supplying your CO2? Is it a DIY set up? A paintball tank set up? etc. Quote Link to comment Share on other sites More sharing options...
chernyi Posted July 2, 2016 Author Report Share Posted July 2, 2016 Canister to regulator to bubble counter to atomizer, its even safe for my shrimps. Quote Link to comment Share on other sites More sharing options...
Fishprinceofca Posted July 3, 2016 Report Share Posted July 3, 2016 12 hours seems a bit long. When was the last time you changed the bulbs? How long has the tank been set up and the Pogostemon planted? Quote Link to comment Share on other sites More sharing options...
chernyi Posted July 17, 2016 Author Report Share Posted July 17, 2016 Hi guys, sorry for the late reply but the situation seems to be stable now after a 70% water change and starving my tank of nutrients. Don't know how it worked but whatever floats the boat I guess. Quote Link to comment Share on other sites More sharing options...
JuanSan Posted August 8, 2016 Report Share Posted August 8, 2016 When you say 30 do you mean celsius? Like 86F? That seems a bit warm! Quote Link to comment Share on other sites More sharing options...
