Sorry, dude... have to stay in my lane on that one. I am no planted tank guy... which makes me the last person that can answer that particular question. I know discus well enough to say the adults will do fine in a planted, so long as you know what you are doing planted tank-wise. There are very few people that have raised juvies in planted tank, and I mean few... I would not recommend even going there with juvies.Well I wouldn't call myself an expert at planted tanks thats forsure but I think I have a pretty good idea what I'm doing. I'm thinking that I'd probably cut back on my fert dosing and co2 until they all got settled in or would you recommend just keeping the same just so that there aren't as many changing variables?
hopefully, someone can give you a more specific answer regarding your planted tank question... I'd consider posting some of these over on Simply as well as this site... both are excellent resources for info on this.
Good luck!
