Algae Needs Sunlight

Algae is a plant and thus needs sunlight. Not much sunlight in a fuel tank. It is a mold or fungus. You either didn't treat it correctly to get rid of it, or where you are buying your fuel keeps reintroducing it. That is the only way it can get in the tank. There are two kinds. One is black and grows on the walls of the tank. The other is like snot and can be found in the fuel. Both will plug fuel filters when it breaks loose after treatment, and has been known to plug fuel lines on rare occasions. I always carry at least two new fuel filters at all times, and have learned how to change them on the road.

We owned diesel trucks for several years. All of our trucks carried spare filters, and drivers knew how to change them. No matter what happened to the truck, if it wasn't running right, the driver was instructed to change the fuel filter, before doing anything else. Usually solved whatever the problem was...

I store full and get my diesel from a large station that turns over their fuel often, no problems yet.

As had already been said, low/empty tank is a problem waiting to happen. We always store our MH with a 'full' tank. I also use one of several products to condition the fuel for long term storage. So far have not had an issue.
The 'other' reason to store with a full tank, is that we always have a safe place to 'retreat' to when/if something goes bad. If there is a major earthquake, power outage or if there is an issue with our house, we can always goes to the MH.

The algae grows at the interface between the fuel and water. I try and keep the tank near full but at todays prices.....
Anway, I haven't yet had a fuel problem, guess I've been lucky as I haven't bought any bad fuel either.
I very seldom add any treatment and have never used a biocide either.

I often have diesel in my tanks that is a year or more old. To keep the microbe problem away, I use Biobar JF, which is very popular in marine and aircraft applications. It works.

I always have nearly full fuel tanks to keep the condensation down. Water in the fuel is the way microbes can grow.
