I have been keeping fish for over 50yrs. When I retired and moved to Fl. I set up a 45 gal planted aquarium. The plants flourished with minimal feeding and no fancy lights.
Recently my amazon sword and the Jungle val started to wilt. I was using 2hr aquarist plant food, and it seemed to work for awhile. In fact I have a 29gal. tank in my shed with the offspring from the amazon & Jungle val. All the plants in the 29 are doing well producing runners and GREEN. I also have a anuba a java fern all doing well in the 45 gal tank.
Flourite is the substrate in the 45 gal and plain gravel is in the 29 gal.
I just tested the water in both systems and the parameters seem to be the same. I also use R/O water for my water changes.
Mystifies me why the plants in one tank are stressed and in the other are growing like weeds.
Any suggestions
I just purchased your plant food and pellets and are awaiting there arrival.
