Ok well I recently got a 50G tank and put pretty much all the plants from my 15g in there (god knows how my fish swam around with ALL those plants in the 15g) and have started to notice the leaves on the plants turning yellow. Well that is on the green looking plants eg Amazon Sword and Jungle Val. The Elodea looks a little yellow but not overly and the Ludwigia looks fine. The Jungle val in particular had entire leaves that are yellow where as the Amazon sword just seems to have more of a yellow/brown tinge happening.


Has anyone got any ideas as to what might be causing this so I can correct it asap? I did have a bubble stone in there for a little while but have since removed it. Could it be that the bubble stone was injecting too much O2 into the water and the plants were starving for CO2? I'm hoping they'll pick up now that the bubble stone is gone but need to know if it could possibly be anything else that's the problem? I don't have a CO2 system in place (no did I when they were in my 15g and they grew fine) but they do have a lot more light now than they used to. Water temp is 28C (82F) and for stocking levels refer to my signature.

Anything else that you need to know please just post here and ask, I'll try to provide the info!

Thanks

Edit: I also fertilise them with a fish safe liquid fert with the recommended weekly dose.
