Plants going yellow!

[MissClaire]

Hi all, just curious on the cause/reason for my plants going yellow in colour, they arn't looking too healthy and how can I fix the plants before they all die!
Is it disese/lighting/nutrients/snails etc etc

Difficiencies, probably iron.

Get fertilizers.

Might not be enough CO2. Need to decrease surface turbulence (not recommended with discus).

Don't rush off, though. Get more opinions, first, seeing as how discus are not very strong and might get hurt by additions to the tank...

Mmmm, yeah I better not change or fiddle around with my tank at this stage, as in the past I have had issues and everything has settled down really really nicely as of late (discus laying/breeding ph behaving etc)
So its mainly a nutrient issue? Not a disease?

 

[Tempestuousfury]

Most likely, no.

A lot of the time, the problems don't require medicine, just additives

 

[handsomeboy]

if its disease youre screwed anyway, as discus might get messed up by med. just feed ferts like iron and substrate ferts in small amounts.

 

[Silly me]

lights?? what lights do you have over your tank.. watts per gallon and type of light.. ie color or make

my plant show the same signs when I dont have enough light over them.. or old tubes..
