Kind of a self-descriptive title...all my vals, rather than growing, are having their leaves turn brown and dead. Any idea why this is the case? The tank is a 29 gallon with a cat litter substrate, the light is in the front of the tank while the vals are in the back, the tank usually recieves a 1.25 ml excel dosage, and the fish are 8 white clouds, 13 danios (11 zebras and 2 pearls), 5 variatus platies, and 1M2F paradise fish. The vals are the only plants that did not clearly benefit from being moved from a sand substrate to the current one.
Have heard from other's that val's don't do well with application of excel.
Some other plant's also, but I have never used the excel so only sharing what other's have mentioned.
Also believe the val's enjoy harder more alkaline water
for they are able to get their carbon from the carbonate hardness of water.
From the fish you have though,it sound's as though you may have fairly hard water so maybe it is the excel causing the plant to not perform.
I haul out handful's of leopard val's from my tanks about every two week's
GH 11-12 pH 7.6.
