The Patented Skimmer Plug offers a simple yet revolutionary method for servicing and winterizing above ground and in ground pool skimmers. A first of its kind, the Skimmer Plug is superior to any other skimmer closure or winterizing device on the market. No installation or tools required. The Skimmer Plug securely fits into the skimmer opening using our exclusive 3/4" thick Rovaseal thermo insulated layer which expands to plug and "grip" the face plate. Thus creating a 100% water-tight seal. Ice is no match for the Skimmer Plug's rigid outer plate. It provides a durable and secure layer of protection throughout the winter. Skimmer Plugs are made to be UV resistant and chemical resistant.
Why is the Ph Level so Important for your Swimming Pool? The Ph level of your swimming pool is one thing you definitely need to keep a close eye on. Each week you should be using a testing kit so you know what the levels are. Ideally you want them to be as close to 7.2 as possible. However, anything in the range of 7.0 to 7.6 is deemed as acceptable and you won't need to do anything else about it. However, if the level is too high or too low than you need to balance it out by adding various chemicals. If the amount is below 7.0 then it is considered to be too acidic. If the amount is above 7.6 then it is considered to be alkaline.
