Looking for some input/help; my tank is suffering a big GHA & Cyano issue

While the debate continues ...

Thanks for your input seabreeze
I've been doing everything you listed with a couple small differences;
I use HCGFO
WCs I'm doing weekly and may change to bi-monthly
I wasn't regularly basting the LR
My Strawberries and Turbos died - I suspect due to Cyano
No coral snow (coral frenzy in my case)
No vodka or vinegar dosing (yet)
All my frozen is rinsed well with RO in large batches, with garlic and aminos added before being frozen in small cubes
