Cheers Clive. The one in the back corner has only been in a matter of days really, I thought it might hide the filter which I've decided to replace anyway. If I remove the outer leaves some CO2 might reach it. I have the Koralia facing towards that direction which is directly above the diffuser. So hopefully it might circulate. I'm in the process of getting an external, just trying to decide which Eheim and one that fits in the cupboard.
Ill trim the outer leaves and see how that fairs. I kinda guessed at some point it might get too big. I have 2 others aswell at the back.
I liked them and in my previous set up they didnt get very big. But I didn't dose ferts, co2 or root tabs etc. now I'm going all out, things will have to change.
This is why i appreciate all your advice Clive. Ill give it a week dosing etc. and ill take a pic of my entire tank and see if you have anymore advice for me 🙂
