The issue with the drop checker has been sorted now and the eleocharis is growing nicely but what is this difficiency with my hc?

Hmm, Im gonna go with low PAR rating at substrate level.

What are your current lighting specs mate?

 

[Nathaniel Whiteside]

Just looked back and have seen its a fluval edge. Is the HC situated close to any corners?

 

[rehman73]

Hi yes it is close to the front corners it is abit shaded also the hc that has the most light is not that bad.i just hope its not light as i cannot do any further mods.

 

[tim]

looks like its melting a bit how often you doing waterchanges mate this is a fairly new setup isnt it

 

[rehman73]

Hi Tim iv been doing waterchange every day for the 1st week and i have cut down to every other day now in my second week,i have read it might be due to high ammonia in the water,could it be something to do with activated carbon in my filter?

 

[tim]

itll be the ammonia leeching out of the aquasoil mate can go on for a while what % waterchange were you doing think most people recomend at least 50% but you can go as high as 90% try going big waterchange trim out melted plants and try to encourage new growth keep co2 high and hc should bounce back with a bit of luck have you added any livestock yet

Any pics?

I think Whitey89 might be on to something, with light. they do need strong light.

 

[tim]

thought most carpet plants need high co2 rehman has a fair bit of light for an edge 2 halogens a pl bulb and led bar from the 46ltr i think mind you whitey is a dab hand at growing hc

 

[Nathaniel Whiteside]

Whos good at growing HC

I was thinking along them lines as the light apparently struggles to get down there. I wasn't aware of any mods. A full tank shot with location shown should help a tad!

If nutrients are all dosed in Ei index
Methods and co2 is looking adequate, as too is filtration. This must relate to lighting being unable to hit the spot due to the beam angle of the LEDs.

He also states, the HC closer to the light source is doing better than that shown.

I'm only an amatuer, but Im sure someone here will be able to hit the nail on the head.

 

[tim]

hey just sayin i wouldnt want him to add more light if its ammonia related mate from the aquasoil rehman mate if you update your journal with some pics mate youll get more advice there and folks can see whats goin on in your tank mate your hc is lovely lookin btw whitey

Tim im doing about 60% water change and i keep ontop of this i dose ei and easy carbo everyother day.

hi i got pics posted in my journal.

 

[tim]

easycarbo i think only has a 24hr lifespan in tank id dose this daily mate just keep doing what your doing and hopefully get some new growth mate worth updateing your journal though good and bad lots of folks check there and offer good advice

This is image is a symptom of poor CO2 at the substrate level. The mechanism of failure is photoinhibition and internal radiation poisoning due to too much light. The plant is starving to death because of an inability to produce carbohydrates.

Reduce the light intensity, increase CO2 injection rate or add liquid carbon and improve your flow/distribution to the substrate.

Cheers,

 

[tim]

thanks clive its always co2/flow related i'd take this advice

 

[tim]

you could use one of these with a diy spray bar across the back of the tank http://www.allpondsolutions.co.uk/aquar ... pumps.html

See, completely wrong end of scale.
Thats why he is the man.

I did kind of barge in without checking specs properly and mentioned that because EboEagles I believe had issues in the very corners of the edge.

Now you know the answer, I expect a full grown carpet by the weekend.

Thanks Clive,i can increase the c02 and flow but if i reduce light intensity then i will get dark spots in the tank also the hc that is under higher light is doing well so im just a little confused here.

Thanks tim for the link i may go down this route if i dont see any results with the flow turned up on the hob iv replaced the impeller for a bigger one (200gph).
