When do I replace a pond liner? 

To be honest, changing your pond liner isn’t that major. What’s more difficult is thinking about the other things you have to do before changing it. When you factor them in, the job is much bigger, exhaustive and time consuming. 

For instance, you have to remove everything that’s in your pond, like the water, fish, plants, rock, algae, dirt and everything else. Plus, try to avoid replacing your pond liner in peak seasons like spring or summer, as that’s when wildlife is at its peak and a key breeding time for fish. Therefore it’s often best to replace your pond liner in the autumn when the temperature is cooling down.

7 things to consider when replacing your pond liner 

Before jumping into changing your pond liner, there are a few things you should take into account. These are: 

  1. Storing your fish 

If you have fish like Koi carp, you’ll want to know how to store them properly. After all, it can be difficult, and you’ll want to ensure you do it right to ensure they survive the temporary period of replacement. The best thing to do is keep them in a holding tank; make sure you aerate the water and give them enough air. 

Following that, make sure the water gets filtration and try to change from time to time. To help with filtration, you’ll want to change the water slightly and feed your fish a bit less. It might be helpful to feed your fish less as the additional waste they create means less work for the filtration. 

2.Size and shape of your pond 

Before selecting and replacing any liner, you’ll want to measure your pond correctly. Doing this will allow you to get a liner that fits properly. When measuring, make sure your factor in its width, depth, length, shape and contours. If your pond has any shelves or ledges, you might want to pay special attention to the design during installation.

3.Selecting the right pond liner 

When it comes to pond liners, there are quite a few to choose from. For instance, you could have EPDM rubber, HDPE, PVC or anything else. EPDM tends to be durable, flexible and resistant to UV. In contrast, PVC liners are often more affordable but have a shorter lifespan. Whereas HDPE liners are difficult to puncture and perfect for large ponds. Also, other ponds have various installation processes; some can be simple, others difficult, so you should be familiar with them too.
