I was poking around the Planted Tank forum, and I came across an interesting thread regarding java fern and anubias melt in a low light 30g tank.
My java ferns always do poorly, so I got interested.
An experienced planted tanker suggested to dose ferts once a week, and do water changes once per month. He mentioned that weekly water changes put CO2 into the water in such a cycle that plants like java ferns may not like it. By waiting 1 or 2 months between water changes, the water chemistry stays more stable.
I have never heard of putting off water changes for 1-2 months, except for Walstad tanks.
Is this advice sound?
