Can't really tell by the pictures. Question??? Are they solid or do they look like there is solid partials and look like a fuzz on the partials? if this is the answer it is trapped food with a bacteria trying to break them down. remove them by cleaning the intake tube and sponge you have around the intake. in clear hot water. Do not use soap. If need be use white vinegar and rinse in the hottest water you can until there is no vinegar smell. If all look just like fuzz it could very well be algae. Again to clean see the above.
