I'm hella jealous of the hydracotle japan carpet you got going on. I've had 1 sprig I've been trying to grow out for almost a year now and I've had 0 luck with it. I have no idea how people get it to grow so fast.
5.5 with occasional excel and t5no coralife light (24 inch) and standard petco black sand and osmocote tabs. I think my problem is my floaters. My salvinia minima is so fast growing I get a tank cover every 4 days and I rip 90 percent out each time. H. Japan has always been a plant I have trouble growing. I'm thinking of putting it in my mini-m in my signature and see if it does well in there instead. Same ferts but higher lightIt grows like a weed once established.
What setup are you running?
Do you dose?
Run pressurized co2?
What substrate do you have?
This plant carpets kinda strange. It forms together more like a push than say grass. On several occasions ive pulled an entire mat of this stuff up, moved it, placed it, threw on some rocks as anchors, and it re_rooted.
It never gets so compact that aerobic gases form or anything. Unlike when i uprooted a mat of baby tears😔
