I have an 18 year old 8m x 4m swimming pool and in previous years I have noticed a slight blackening of some of the white tile joints. This year perhaps because it has been much wetter weather, the area of black joints is much much greater and quite unsightly. I presume it is algae build-up and have tried chrystal chlorine and brushing to no avail. How do I eradicate this.

If it doesn't come clean from brushing it's probably black algae.
You should apply a phosphate eliminator (No-Phos or something similar) as well as a black algae algaecide and
shock the pool. Once the algae is eliminated follow the maintenance doses for the No-Phos. Once you eliminate the phosphates you will eliminate all algae (that's what algae feeds on)>

If your pool is full of water, then the tiles will not know that this year we have had wetter weather, because they're submerged in water all year round.
Presumably there are chemicals and cleaning methods which should be routinely carried out to prevent any build up.
