Made from corrosion-proof polymeric material, the Hayward S210S is part of the Hayward Pro Series. The high-rate sand filter requires 200 lbs of sand to filter particulates from the water. This debris collects under the sand bed; when too much debris accumulates, the backflow feature flushes it from the filter. The S210S has an effective filtration area of 2.20 square feet and a design flow rate of 44 gallons per minute (GPM). The S311SXV is a high-rate sand filter that works with in-ground pools, spas, fountains, and solar heating systems. It requires 350 lbs of silica sand. The spherical shape of the filter allows pressure to diffuse better within the tank without weakening it. It has an effective filtration area of 4.95 square feet and a design flow rate of 99 GPM. For pools that hold up to 47,000 gallons, the S311SXV filters the water in eight hours. The Hayward Pro-Grid Vertical D.E. pool filter uses diatomaceous earth; as with sand, debris and algae get trapped under the diatomaceous earth while water passes through unimpeded.

The filter needs three lbs of diatomaceous earth. The top and bottom of the tank connect with a flange clamp that allows easy access to internal components. The DE2420 handles an effective filtration area of 24 square feet, and it works on in-ground pools and in-ground spas. It has a design flow rate of 48 GPM for public pools, and 60 GPM for residential pools. It handles pools between 23,000 and 28,000 gallons in size. The Hayward EC65A uses a diatomaceous earth filtration system and requires a total of 6 lbs of diatomaceous earth to filter all dirt and algae from the water. It offers an effective filtration area of 26.9 feet and works at a design flow rate of 54 GPM. The "bump" feature unique to Hayward's PERFLEX line periodically regenerates the diatomaceous earth to keep it lasting longer between changes, as the filter runs continuously. The EC65A works with a maximum pool size of about 32,000 gallons. The Hayward S200 is a high-rate sand filter for in-ground pools and spas.

The corrosion-proof tank features ABS, a thermoplastic noted for its durability. The filter has a design flow rate of 44 GPM and an effective filtration area of 2.20 square feet. It is ideal for pools that hold around 21,000 gallons of water. The S200 features sight glass to show when the filter needs backwashing, the cleaning method that runs water backwards through the filter to flush dirt from underneath the sand bed out of the filter.fish tank for sale in redditch The Hayward S220T uses 250 lbs of sand to filter pools no larger than 24,000 gallons. fish tank for sale in riyadhIt has a design flow rate of 52 GPM, and an effective filtration area of 2.64 square feet. fish tank for sale in pretoria

Perlite is the white, light weight material that's added to potting soil. Perlite has a very high surface area. It would seem to offer great possibilities for either mechanical or biological filtration. Another plus, for freshwater systems at any rate, when the Perlite needs to be changed, it could be immediately reused as soil for house or garden plants.

As an aside, when doing water changes, water from the aquarium is a great source of fertilizer for plants. The largest distributor of Perlite on the east coast is The Schundler Company . Perlite Being Used In A Fluval Filter Perlite is available in three grades: fine, medium, and coarse. The fine is a powder with the appearance of flour. Fine Perlite can be used instead of Diatomaceous Earth in a Diatomaceous Earth filter. The medium grade is twice or three times the size of grains of sand. The coarse grade is about the same size as gravel. The coarse grade is what's generally used with house plants. I set up a tank using the medium grade of perlite in a fluval brand aquarium filter. It's distributed by the Hagen Company of Canada . With the relatively fine grade of perlite, it was necessary to sandwich the material between sponges. This was easy, for the filter is designed with three chambers for this very reason. Peat moss is often used in the center chamber.

A Closer Look At The Perlite In The Fluval Filter Cartridges The next morning, the water was crystal clear. I placed a dozen Blind Cave Characins in the tank the following day. The fish are extremely active and are doing very well. Their appetites are phenomenal. The water remains crystal clear. To give the perlite a thorough test, I next set up a fifty gallon aquarium with oscars. I continued to use the large Fluval filter with the Oscars. A smaller Fluval went to work on the Blind Cave Characin tank. I'm now using the coarse grade of Perlite in the middle cartridge. The medium grade continues to serve in the top and bottom cartridges with the sponges retaining the Perlite within the cartridges. I've found the Perlite to be great for both biological and mechanical filtration. It really cleans and polishes the water. Before you put the Perlite in the filter, rinse it out in a net under the tap. If this isn't done, the filter will, at first, give a milky output.
