I wanna ask, do u guys use pure water or tap water. I've been usuing tap water from the farrer road area for awhile now, and i suspect that it might be the problem for some plant failures.
What are your experiences with tap water? Is there a way to obtain pure water cheaply?
about 25% of my new plants gotten from elsewhere (Trifid park, etc) have perished under my setup, and i dunno why...
Also, anyone know how ta prevent slime and algae?
