I’ve had an algae problem ever since I can remember in my 28 gallon cube and I’m starting to wonder if it’s because I didn’t kill all the stuff that might have been in it when I first got it (it was used from a friend) I cleaned it well with plain water but didn’t use bleach or anything to kill lingering algae and who knows what else.
I’m going to upgrade but I plan to clean the cube again and thought this time I’d run bleach through the tank, rinse well, use prime rinse again before I add new sand, and salt water.
I’m moving a smaller tank into it and planned to use the rock, and salt water from it to start off the cube.
Will that be sufficient or do I need to go through a cycle all over ?
I definitely do not want to harm my fish by moving them if it’s not safe

It was beginning to seem under control and the phosphate was dropping now it’s gotten worse. I do weekly water changes and have been consistent for several months
