Hi all,

I have a sand substrate tank and was trying to grow Amazon sword plants because i heard they were relatively easy to grow.

The leaves seems to be appear very brown and look like they are dying.

I have tried using root fertilise tabs and water based fertiliser from a bottle but they are still struggling to grow?

Any suggestons?

i dont really want to go down CO2 route due to my inexpertise in this rea and costs etc

If your lighting isnt good you wont grow anything properly...(If it happens to be old flourescent tubes they need to be replaced every nine months) The light output diminishes over time in flourescents..

Also maybe try liquid Co2 (Easy Carbo) as opposed to an injected Co2 system...It has the added benefit of acting as an algecide...Algae hates it and plants love it!

Is the Amazon sword newly purchased or have you had it awhile Dk1981?
If it is new I ẃould think that the leaves are melting back as most of the shop bought plants are grown emmersed.
The leaves have to go through a physical change once we immerse them as they are not absorbing things like co2 and oxygen by being in direct contact with them in the air .
The plant is now being limited by the dissolved amount of both in the water column.
The new leaves that grow will have physically adapted to its new environment and may not look the same as when it was bought.
If it is an established plant that is dying back ,lighting, co2 levels and nutrient deficiency may be at fault like gunnered72 previously mentioned

bought it about 2 months ago.

have T5 bulbs as my lights i think they are called, not especially strong as far as i know.

i did some root tabs and lquid fertiliser but they dont appear to be thriving at all

i preumse both the lights and sand subtrate are my key limiting factors?

What other plants do you have in the tank?
Are they suffering from the same symptoms?
Is there any new growth visible on your swords?
