After a lot help and advice from @arcturus on the other thread, I think the cause of the algae and MC going brown is down to me adding the 2nd light, upping the C02 but forgetting to up the ferts. School boy error. So plan of action is to just run the 1 light but raise it up higher than it was before. Monitor for a week or 2 and if I'm still getting growth issues with the Palustris in that rear corner, then add the 2nd light but increase C02 and ferts this time
Something like this but without DVD cases. Lol
