It is not if water enters your fuel system it is when water enters the system it can cause bacteria growth. Many species of bacteria, mold, and fungus can grow in diesel fuel but not algae.
Algae growth in fuel is a misnomer for the problem. What looks like algae may be in fact asphaltene or diesel sludge/fuel bugs/fuel microbes. Asphaltene is a chemical problem inherent in YEARS OLD diesel fuel or it most likely is a bio-mass that forms around bacteria to protect it.
Until know what exactly what the problem is you cannot treat it and get the desired results….a clean tank and no ore plugged filters or poor engine performance.
Have you used a biocide and nothing got better?
Test the fuel now and we then will know the direction to go.
DS-1 Fuel Test Kit
Individual test per package.
Works in ANY fuel.
This will detect Fuel Microbes (BACTERIA or MOLD) between 24 and 36 hours after exposure.
NO spots are good news. Any reaction is bad news.
Test for water contenet and bacteria.
1 each DS-1 Test and 1 each W-1 water detecting capsule.
Pass or Fail / Water in Fuel Test.
This is a PASS or FAIL test.
This test will indicate the smallest amount of suspended water in diesel. Depending on the fuel blend and the amount of biodiesel you may see between 1000 PPM and 1500 PPM will be detected.
Any detection of suspended water is not good if the detection powder turn 100% pink. The fuel FAILS
The kit consists of 5 each test tubes with the reaction powder capsule in them and one transfer pipette.
1. Remove one of the capsules from a test tube
2. Do not put fuel in on top of the capsule.
3. Take fuel samples from as many locations you see fit using the pipette.
4. Add fuel to the empty tube FIRST. Approximately 3/4 full.
5. Take the capsule and open it and pour the continents into your test tube with fuel. Put on the lid and shake for 10 seconds.
6. Set the tube on the table to allow the mixture to settle and examine the results. 1000-1500 ppm water will give you pink spots in the powder. More than 1000 ppm water will turn all the powder hot pink indicating the fuel contains excessive water.
