I brought my floating plants inside into a 20 gallon aquarium filled about halfway and hung a 14w LED grow light (https://www.walmart.com/ip/Great-Va...th-Integrated-Outlet-up-to-10-Units/852904069) over it. It's been a couple of months now and I've had to compost a ton of salvinia because it tries to take over, so it's working well, but I've notice that the frogbit that is directly under the light tends to turn pretty yellow and look unhappy whereas the pieces that have floated more towards the edge that are not directly under the light are looking greener and happier. Is the frogbit just getting too much light?
The light is about 4" above the water surface.
Are there just too many plants and not enough nutrients?
I don't have any fertilizer or fish food to add to it. I've tried tossing in a few pieces of cat food to try to "feed" the plants but I don't think it does anything and I can't afford to buy anything either.
Should I take some of the frogbit out so there's less competition for the nutrients? Or should I try to move the light to one side so there's more area out from under it?
