. Is there any additive I can add at this point to help after blowing whatever back in tank.

Long story short I bought my boat and left to deliver her, got about 5 miles before engine
shut down from a substance that looked like putty in the dip tube, removed tube, blew it out and drove on. Got about 10 miles happened again. Probably happened 6 or 7 times total before I got it all out, but since then no issues.
You don't know if you have a golf ball sized piece of biomass, a pea sized or the whole bottom of the tank covered in the stuff. I didn't sleep well, I just knew I had the whole bottom covered and when we hit rough weather
it would break up and we would be screwed, but seems my total amount was about maybe a tea spoon full.
Do you have an access cover where you can get into the tank? If so it will be work, but it can be cleaned or at least you can get an idea what your facing. Some services can push a hose down your filler tube and recirculate fuel through a filter to polish it, I doubt this is a perfect answer to your problem though.
I know of no additive that will break this stuff up so that it can go through the hose and be caught in your filter, you do need in my opinion to be using a biocide additive in your fuel as a preventative, but as far as I know it only prevents growth.
If nothing else maybe bumping your problem to the top again will get someone who knows of a fix.
Post your boat type, maybe someone else who has one of the same can help?
