In our FAQ section, you will find our recommended time frame for opening your pool. We would like to expand on that information in order to help you make an informed choice for your opening date. We typically suggest a solid cover as they tend to do a better job protecting your pool finish and keeping the water clear. However, we routinely install both mesh and solid safety covers.
We always suggest giving 7-10 days before you plan on swimming. Many factors can affect how your pool sits over the winter, from the condition of the water at the time of closing to how mild (or severe) the Winter is along with any organic material that gets into the pool. And if you have any mechanical problems and the parts need to be ordered, that will also delay the opening process.
For mesh-covered pools, we suggest opening in the first half of April. The mesh is permeable, allowing rain, melting snow and even sunlight to get through. This will affect your water balance, and once it starts to warm up in early Spring you risk having an algae bloom in the pool. This can end up costing significantly more in chemicals at the time of opening, even more so if the pool needs to be drained and cleaned. Opening a mesh-covered pool in early April cannot guarantee you will not have algae, but it gives you a greater chance of pulling the cover back and revealing crystal-clear water.
For solid-covered pools, you can usually hold off until early May, but much longer than that and you are risking an algae bloom as well since the weather is usually getting quite warm by that point. The warmer it gets, the faster algae can grow.
Keep in mind that both mesh and solid safety pool covers are designed for just that – safety. Wind will lift the edges up from time to time, allowing debris and leaves to blow in over the course of the winter. Pool owners with both types of covers should expect to need the pool vacuumed at the time of opening.
While nothing can guarantee that your pool opens up crystal clear, there are steps you can take to try and keep everything in good shape, such as a monthly winter watch while the pool is closed. This means lowering the water level in mesh-covered pools, clearing debris off of solid covers, and balancing the water to ensure sure the PH does not get too high which can cause scaling and calcium crystals. Balancing the water once a month over the winter can also help prevent severe algae blooms, especially in mesh-covered pools. And if you have a mesh-covered pool and do not get a monthly winter watch performed, it is a good idea to at least balance the water one time, about a month before you plan on opening. This can also help prevent problems.
