Bought some a while ago off a forum member elsewhere and when I put it into the tank it died off bit-style. I thought I'd lost it all, but let the remnants floating as it did not die completely. It has grown back a tad (few mm of leaves up to a few cm of leaves) but I can't keep it in the substrate.

Substrate is rounded pea gravel. There aren't roots on this plant to talk of but when I push it into the substrate it stays for as long as I'm facing the tank then (I suspect) the SAE's, cories or loaches 'inspect' it and it's back at the surface. Unfortunately, with the amount of the flow I have in there now, it ends up in the corners of the tank and doesn't get enough light to actually grow - it subsists.

Any ideas?

I'd give plant weights a try.

Mature, sensible signature required for responsible position. Good prospects for the right candidate. Apply within.

Thank you for the suggestion, but it isn't possible. There's nowhere for the weights to be placed unfortunately.

Shouldn't Blyxa have roots? /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

Cake or death?

I imagine it should, but they haven't regrown from the initial die-off. I'm quite surprised that what I have is still alive, but it has regrown leaves (a little!) nothing else. I'd heard that blyxa was extremely sensitive to changes in it's environment (especially CO2 levels) but I was pretty shocked at how drastically it died off after I put it in the tank.

Aaah I see. Have you ever kept crypts Chrissy? Most are a bloody nightmare at first too. The only suggestion I have is to try pushing it further into the substrate than you would normally. I know everything you read generally tells you not to do this but true aquatics like Blyxa will be ok ime.

Yes Matt, got about 4 varieties in the big tank and I know what you mean! Will try shoving them in there a bit more. TBH, whenever I struggled with a plant like this, I let it float for a bit to encourage the roots to grow (crypts included) so that I had something to shove into the substrate.

I've also bought a solenoid so that I can 'overdrive' my CO2 during the day. I'm running approx 30ppm atm, but blyxa is alleged to love the old CO2 and I gather that it is becoming a little more popular to push up the CO2 during the day a little. Will need to be careful with this obviously but if I can get the Blyxa to survive until I start it, it will be my indicator of success.

Will let you know how it goes.

TONS of light (above 2.5 WPG) and TONS of CO2 with lots of nutrients (very phosphate hungry) and Iron.

If any of the above are missing it melts to nothing very quickly.

Only grown it succesfully once and that was more luck than judgement. Might try some again in the trigon in a couple of months.

Ah yes, forgot about the lighting. I'm only just over 2WPG unfortunately. Dosing full EI though I think I need to up my dosage a bit more.

It is your substrate... Blxy will take off like a rocket when the right conditions are met. I just threw away about 2 quart-sized bags full... I use ADA aqua soil, but the cheaper and still almost as goo IMO Eco Complete will work great for you. I know this is a huge undertaking swapping out substrate, but if you are serious about the planted tank hobby then you are gonna wanna make that change eventually or I fear you will continually have these types of heartaches... Blxya is a HEAVY root feeder but will also pull from the water column but prefers not to. It is actually a stem plant and will through out TONS of roots to anchor it. If you are dosing in EI and injecting CO2 with 2 WPG of light your problem is substrate. Hope this helps. Good Luck!
