How to raise the pool fence height

[coolnav]

Hi,

I am in the process of improving the usability of my back yard and decided to install a Deck. I am planning to stretch the decking all the way to the pool fence. This is going to raise the ground level and thus need to increase the height of the fence proportional to the increase in deck height. I am inspired by the low level DIY decks in this forum and decided to go with, the deck will be between 300-400mm above ground level. Would like some suggestions to increase the fence height. I have limited budget, so removing and installing a new  fence will be out of my budget, appreciate any suggestions or help.
