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?


Sounds like you do not have enough light.

You do not say how many watts you are putting in the tank at present.

If you have a standard florescent bulb, and cannot modify the hood, then
overdriving the bulb is the only practical option. It just takes a minor
wiring job and no modifications to the top or hood are necessary.

Search on ODNO (Overdriven Normal Output) and 'florescent in Google and a
ton of info will come up.
