Viewed under microscopes, diatoms show a huge variety of shapes with many interesting and beautiful patterns. It must be free from interfering cell components. The cell wall (frustule) is composed of two halves (valves) that fit into each other like a pill capsule. Take the scrubby out of the tank and squeeze it out in the bucket. So phosphate is literally a part of life and there’s no getting away from them completely. Pick the gravel vac up out of the sand, unpinch the hose and get up as much of the cloud of algae as you can.5. Nerite Snails – these little guys are great at eating up brown algae. Bacillariophyceae. A particularly important feature of diatoms is their silica-based cell wall, producing an especially distinctive appearance that can vary greatly between different species. During this process, the daughter cell also takes a valve of the parent The hydrated silica that makes the cell wall of these organisms looks more like opal, which is transparent, forming what resembles a glass house for the algae. Diatoms also have ranges and tolerances for other environmental variables, including nutrient concentration, suspended sediment, flow regime, elevation, and for different types of human disturbance. The diatoms pop up to eat these excess nutrients. As fish waste breaks down, it puts off ammonia (NH3 ). Read more here.
