"Ok I will def start with all that stuff. The guy I buy my salt water from says he gets it shipped in from the ocean and it's at .025 always. I feed pellets and frozen and rotate but I am going to go to just frozen and one block per day and not twice a day. I can remember what good I just a new food today I will look at it when I get home.
Thank you for all the advise"
There's a lot more to ocean water than the specific gravity or salinity. WHERE in the ocean? OUT 10+ miles, or right at the causeway? Test the LFS water next time...you may be surprised.
Some larger water changes more frequently could help. 20% or less 2 -3 x per week til nutrients start to come under control.
Do you have a skimmer? If not, consider getting one.
regarding the frozen cubes.....i like to cut them up into quarters and feed throughout the day. But straining them is a great way to reduce the nutrient import.
Time, attention, and maintenance, making small incremental changes until you arrive at a desired outcome with your system will be the best route. This method of approach to the issues at hand, namely algae and fungus, will be the surefire solution....as the system balances and the system parameters stabilize, the algae and fungal issues should stabilize with it.
More details about your setup and maintenance schedule, inhabitants, etc will help also.
