I have just started a new 60liter aquarium in which i plan to keep mainly aquatic plants. i have purchased some aquarium planting stuff (sorry, im not sure what its called) its mainly peat, clay, organic matter, and so on. the brand is JBL. I know that when filling the tank your to try your best not to go directly onto the medium of gravel to try not to cloud the water. well im absolutely sure i didnt mess it up. but the clay is suspended in the water, not all of it, but you can see clouds floating around the water. i;ve done a 99% water change and its not helped much( visibility has improved by 40% - 5cm) any tips, suggestions are very much appreciated.
