Most of the plants in my 75 gal. are doing horribly, especially the vals. When I purchased several approximately six to eight months ago the leaves were thick, about an inch wide, and healthy. Soon after planting in my tank, I began to find one or two leaves floating on the surface every couple of days. Now the widest leaf is maybe
one-fourth of an inch wide at it's widest point and that's being generous. In everything I have read, people say how they grow so profusely and are such an easy plant and well, even though I am ashamed ... here's what mine look like:
Additionally, I purchased some anacharis about a month ago and put some (floating) in this same tank and I think one piece has miraculously produced one one-inch long root! At the same time, I put several pieces (also floating) in my 10 gal. betta tank and it is growing like crazy and in fact some pieces are almost 18 inches long now with tons of roots that are five or six inches long.
On the bright side, my anubias and java moss grow very well in the 75 gal. tank.
My 75 gal. has t5ho lighting (2x54w) 6500K bulbs. I add 5 ml Flourish Comprehensive once a week one day after my water change. I only have a gravel substrate. For filtration, I have 2 Marineland Penguin 350 HOB's and two Hydro Sponge Filter 2's. I do not use carbon in my HOB filters - only filter pad material.
Can someone pleae tell me what I'm doing wrong and help me figure out why my plants are not thriving?
