Major Algae Issues need expert help lol

ok ill tell them about the feedings, and they only run like media thru it, ie carbon, phosban, um nitrate sponge and one other thing i believe. so there is none of the orignal media they gave me. would my skimmer be enough filtration w/o any other filter? um yes they do water changes once a week about 5-7 gallons. and whats a filter sock? u mean just a sock to sit in my skimmer?

 

Excess nutrients like phosphate, nitrates etc. A dirty canister filter often traps nutrients What is your photo period ie. how many hrs/day do you have your lights on? A good CUC will probably help control the algae, too???

There are some commercial dry foods also contain excess nutrients and other undesirable things like nitrates, phosphates etc so I strain/rinse my fresh/frozen foods before feeding my tank. You can add a phosphate remover and increasing flow in your tan. Also using RO/DI water and a high quality salt with minimal NO3, phosphates etc like Tropic Marin will really help too.
