Well, I have decided the tank is cursed. LOL I got rid of the algae problem with the light issue. Had them on way too much. And I have lost more fish. I lost the last golden algae eater and two of the guppies that I decided to put in it. One day they are fine the next they are dead. I sat there for a good hour examining all of the fish. None of them appear to be sick in any way. Nobody swimming funny, no slime, no white spots, no visual signs of external parasites, nothing. I think my daughter is just going to get a new 29 gallon tank for her B-day in December. Maybe even sooner so it can cycle. My son has a 20 and that is the smallest tank I will do after I get rid of this one. Maybe I will turn it into a terrarium or something.
It definitely has something against fish.
