Yellow leaves on water plants

I have a small water garden, maybe a foot and a half by a foot and a half, with a few plants, a fish and a snail. The leaves on the the plants are turning yellow and dying. I don't know why. My books suggest nitrogen deficiency but they aren't specifically about water plants. If I fertilize with a nitrogen fertilizer, will my fish and snail still be ok? Anyone else experience this?
thanks, annie

Go to a pond store, they are everywhere and buy pellets especially made for pond plants. You can buy them at Lowes or Home Depot, as well. However, your one fish is pretty miserable in that tiny amount of water. Rather cruel, in my opinion to have this condition for a poor fish.

The smaller the pond the more difficult it is to keep one stable. I have the same problem with water plants, but their purpose is to remove fish waste products. If you don't have enough fish to fertilize the plants you can use water soluble fertilizer, plant stakes, like tomato stakes, the kind for small pots. I wouldn't use the tree stakes the are sometimes made with ammonium sources. Ammonia is not good so read the label of the fertilizer and get a nitrogen source other than ammonium nitrate. I would use small amounts of a good flowering soluble fertilizer like 1-2-1 (type, like 6-12-6) for floating flowering plants. If your plants don't flower a 1-1-1 type fertilizer is a general fertilizer and works well in water plants too. You may experience an algae bloom from using too much fertilizer, so I would start small and check every 3 days for improvement in color.
Or you can go to a pond place and pay more for pond fertilizer.

Feed you plants, take ordianary 10-10-10 or 5-10-5 and wrap a few teaspoons in a coffee filter or two and bury it among the roots. Your fish should be fine but could live in a bucket for a few days if you were concerned. You could buy pond food but for your pond a small container would last you a long time. High water temps will also yellow the leaves.
