Help needed with 27L Nano(plant I.D needed and what fertilizers to use)

I setup a nano two weeks ago back with pfp and nutrifeed as substrate capped with pebbles. Light is 20watt cfl 6500k. Filter is HOB. No fish as yet tank was cycling and my plants are dying and I don't know why so once the plants stop dying will put about 10 guppies. I have these plants for a year now and they grow well in my other tank, and are still in that pots they come in, that tank just as a 10000k light and guppies.

Please can you help I.D these plants and if they easy/medium/difficult growers. Also what ferts I should get from the seachem range for these plants.

NO:1


NO:2
This is java fern right?

NO:3

 

NO:1=Ludwigia repens
NO:2=java fern
NO:3=Hygrophila corymbosa 'Siamensis'

 

Looks like potassium deficiency,they look like they also need more light.:idea:

 

Tie tge java fern to a rock or wood. It doesnt want to be plented

 

I agree on the ID - and please take the plants out of the pots! That rockwool can be harmful to your fish!

 

Thank you all for the advise with plant tanks I'm blonde

@DewaldC thanks for the I.D will added another cfl and will buy seachem potassium today what else ferts should I get?

@Ryno I will tie the java ferns to the rocks

@tracyp I didnt know the rockwool was harmful, will take out the guppies from that tank weekend will keep 10 males for my nano and will give the rest to a friend.

 

Maybe get a all in one kind of product.:smile1:

 

@DemwaldC What you recommend

 

Tropica specialised fertiliser.

@DewaldC I did some reading last week on TASA and was looking for Tropica because it's easy to dose, but I can't find it at any of the LPS. And Durban's biggest Pet shop keeps seachem so that's why I want to buy the seachem but don't know what to buy in the range. Do I need excel, flourish, potassium ? and any thing else ?

 

Trace, iron, nitrogen, phosphorus...

 

Hope this Helps http://www.seachem.com/Products/product_pages/Flourish.html

 

Flourish says it as iron will I still need flourish iron? I don't want to overdose

 

@DewaldC I got Fourish, iron, potassium and excel yesterday and started dosing from last night my lps will get me tropica in a few weeks time and I want to know how much more light I need ?

 

How big is your tank?.

 

450x220x300 but the light is about 500mm away from the substrate
