Out of sight out of mind LOL.
Living in a rural area, we rely solely on
tank water. Our tanks are either FRP or poly tanks. They all stand in the full sun, and the
water can remain in the tanks for long periods of time without drainage, years in fact. Individual
tank capacity ranges from 2,000lt to 25,000lt. We have nearly 100,000lt in total.
Every few years I'll drain the tanks (sequentially) and remove sediment (minimal). However, in the 15 years I've never come across any algae. Maybe any potential algae is killed off by the natural 'additives' (or flavours if you like, you get my drift) contained in the
tank water. The only way sunlight can get in is through the
tank inlet, which is 400mm in diameter. The only substance that I've come across inside the
tank is pollen from nearby gum trees, which floats on the surface.
I wonder perhaps this algae problem that some people experience is maybe due to the quality of the
water? Certainly sunlight does play a role - look at fishponds or poorly maintained swimming pools, etc.
