I have a 120 ltr tank (jewel rekord 120) that has a mixed community fish and
gravel base.

The main problem with the tank is that it is low light (i.e one tube -
Arcadia Freshwater). Fertiliser is added, and a yeast C02 is used.

I have planted previous a mixed plant pack (requesting more low light plant)
but over time a number of these plant have died off. I have added a second
pack, which again over time a number of plants have died off. This has now
got to the stage where I have no plants left except for Java Fern which is
truly flourishing to the stage where either I will have to take off the
babies and replant, or take large amount out of the tank. The fern is
growing directly in the gravel and has large root systems when removed.

Is there any specific reason why Java Ferns does so well and everything else
dies off slowly? is there something I should be doing (I cant add more light
due to the design of the tank)

Even the basic pond weed

I would like to add some other plants to the tank (preferably something tall
at the back). can anyone suggest something that is likely to do well in the
current conditions?

I would restate your problem. You have the wrong plants. There are
many plants that do well with low light. I have 5 tanks with low
light levels and all have healthy plants. I don't use fertiliser or
CO2. Just the natural fish waste.

Do a web search for aquarium low light plants. I just did a Google
and got 82,500 hits. Ask your LFS for suggestions from what they have
in stock.

Others will suggest increasing your lighting. This leads to many more
plant choices. I found plenty of low light plants and I am well
satisfied.
