Without seeing your water, I am going to guess that the liquid algaecide you are using is a quat (quatenary ammonium). It is an effective algaecide but it can cause the water to get a little "sudsy" or "foamy". You may have had just a bit too much in there. A way the old service company guys would check your algaecide level was to put their hand in the pool and shake it around. If it foamed some, then you had enough. Usually a good shock will clear that up.
It sounds like water mold.

It is easy for soap to get into a swimming pool, because the people who swim in that pool have washed themselves with soap and may not have rinsed all of it off. Soap in pool water then causes bubbles to turn into suds. Anti-sudsing agents are available, although at some point you may just prefer to drain and re-fill the pool.
White suds are usually the sign of a chemical reaction or pollution in the water. So, yes it is possible that it is harmful to the fish.
Suds would not be caused by the generator. Certain algaecides can cause suds, or just conaminates from bathers, in which case an enzyme product will fix that. In some cases very low calcium can cause that.
There are chemicals in them that create a chemical reaction causing suds.
To make suds you put hot water into your sink with some soap. When the water hits the soap, you'll get suds or bubbles.
If you like suds.
Suds refer to the bubbles that are formed on top of water, which contains soap. Water that has been infused with soap or any other similar synthetic detergent can create suds.
It means you have algae in the water.
Pour on talc powder, or puff it out like smoke and aim it at them. I always do it after a bath, simple things make me smile :-) ...
Rice with water!
soap and water
One person suggested:-Try to put salt on the suds... If they are detergent suds try making up a mixture of lightly soapy water. (Soap not detergent)Put it in an atomiser and spray some on the suds, I think the suds will start to self destruct. Detergent and soap don't like each other. Use as little as possible to get the desired effect as I am sure pools don't particularly like soap either!
