I have a 55 gal tank that has been running since sept or oct. It has 4 40 watt light tubes providing light for the tank. I add Flourish once a week as directed. No CO2. Fairly large fish tank gravel substrate. Most of the stem type plants in the tank are doing very good, but none of the grass type plants (Vals and Sags) are growing at all. Most of the grass plants turn yellow then white then turn to mush. I did have one grass plant that produced another then the mother plant died. The plants sometimes will get new growth. New leaves a few inches long but they are yellowish in color. I was at a petshop in another town a week or so ago and the clerk said that it maybe the gravel in the tank is to large/ harsh for the grass like plants. I purchased a Val in a pot, and put the whole pot in the tank. The new plant is still nice and green. I was wondering if it is possible to add or change substrate on a up and running tank without messing up the fish? Could the large regular tank gravel be the problem with my grass type plants?
Should I just try to replant the plants in pots of some sort? Any other ideas or suggestions?
