SpongExcel is an ionic silica solution designed to enhance the growth rates of sponges and gastropods in marine aquariums. By adding just one drop per gallon of water, you can increase the ionic silica concentration by approximately 0.20 ppm, providing a controlled boost that helps improve water quality by increasing the rate at which these organisms absorb latent organic material. This product is particularly beneficial for systems housing spongivorous fishes such as marine angelfishes and butterflyfishes, offering them an enhanced natural food source.
