I asked this on a different place and didn't get a single answer, so maybe here I'll get an answer.
I set up my 10 gallon tank. Rinsed gravel, *took me an hour*, rinsed large rock and scrubbed with a brush, checked with vinegar to be ok - no fizzing, tied my Anubias to it with some thread. Filled the tank up with dechlorinated water (used prime), planted my Giant Temple's in, place rock w/ plant, put decor in, rinsed filter and heater, put them in and turned everything on. Added API's iron plant supplement.
Now I have a whole bunch of bubbles hanging out at the top by the filter of my tank and all my plants are dying.
