Before I dump rid-x in my tank, could someone give me a walkthrough

Hello all
So algae has gotten out of control in my tank - the curse of having tap water phosphates over 3 ppm. Just about every type is in there (no bba…yet). Considering the only occupant is a red wolf fish, anything that will eat algae is out. At the moment, the main type is cyano. Ive tried chemiclean in the past, but after a few bad experiences I’m done with it.
That brings me to the probiotic method. I remember a while ago I was suggested to use rid-x but that it would take a while to see an effect. Me being impatient went the chemical route with little success.
So that brings me here.
I have a good enough idea of what to do from the sticky on it, but if anyone has any wisdom on the topic they’d like to share, I’d be glad to hear it.
Thank you and happy holidays!

I put a tbsp in a filter sock below a slow flow, hanging in a sump.
The beneficial bacteria are inert in dried form (the way it came packaged, at the hardware store), in a sort of flour mix, which can get pretty dusty, especially in the tank if left to float around
After a couple days, I assume the bacteria have dispersed, I pull the sock , and dump the glob of odors flour in the trash, or compost.
If no sump, hang a sock, or some sort of bag (the feet of pantyhose might work) near the effluent flow of of a filter so they disperse, even the bag inserted and used in a hang on back filter might work, near, or that that gets plenty of dissolved oxygen.

I'd put a tbsp per week into a sock in the sump, running about 400 or 500 gallons of tanks
