Hey Guys, Came across this site as I was surfing the web, I've been running a diy tub pond for months now and everything seems fine in terms of ph/gh/ammonia and nitrates etc. Problem is, each time I purchase plants they either get eaten up or die which I can't comprehend as to why. The only successful plant I've managed to keep was elodea. which has been running for months now. Here's a picture of when I first started and the pond as it is currently. Btw I only keep guppies in that pond right now and the substrate I'm using is aquarium soil. Any suggestions would be thoroughly helpful. Thanks in advance !!!
