Anubias Leaves Turning Yellow

[nagukush]

Hi Friends,

I have a lot of Anubias in my Tank and they're the only plants in my Tank. I have DIY Co2 running and very low light, so I dont dose any ferts. I see that a few leaves of some of my Anubias have turned yellow colored and the other leaves are also starting to show these signs of yellowing.

Just wanted to know if this is a deficiency and how do I rectify this. Do I need to dose a little ferts then ? Also is there a particular chemical element that will rectify this ? Somebody told me that Anubias need potassium to grow well - is this true ?

Kindly guide me as I dont want to lose my precious Anubias. I got them with great difficulty and they've been growing so well all these months...

Kindly advice and help me...
Regards and Care
Kush

i would say yeah, you need to add some ferts. i'm not all that experienced though, but i think co2 is not needed in a very low light tank

You don't need CO2 with the anubias and yes you are likely low on iron. A general purpose fertilizer may help. I used iron tabs with mine and it did wonders!
