This is so that they have enough energy for making their own food by means of photosynthesis. Without sufficient light for photosynthetic activity your plants will remain stunted or die. So part of correct saltwater aquarium care involves making sure that your aquarium provides sufficient lighting for plant growth.To make sure that your plants are getting enough light keep the following rule of thumb in mind: For each gallon of water in a tank you will require 3 to 5 watts of light. Most aquarium lighting systems are below that level, however so you may need to shop around to find adequate lighting to make sure you are providing the proper saltwater aquarium care for your plants.In the natural aquarium the fish and plant populations are perfectly balanced and compliment each other. Marine plants create shelter, shade, and even food for your fish! Plants that are well lit will give off oxygen and this creates a good environment for your fish. So proper saltwater aquarium care makes your tank healthy and provides optimum conditions for plants and fish alike.The fish will, in turn, feed off the carbon dioxide released by the fish. Plants also feed off the waste that fish produce. This helps to absorb some of the waste that might become toxic to your fish. So as you can see proper saltwater aquarium care means maintaining a healthy balance for all the life in your tank.To provide proper saltwater aquarium care for your plants and fish you need to make sure that conditions in your tank are optimal. Plant growth needs water which is at the correct ph levels. It also needs the water to be at the correct temperature for growth and survival.
