I found that beer and wine (champagne) yeast did not like baking soda. Bread yeast does like baking soda. You can add 1/8 teaspoon bread yeast to the mix you have now and it ought to work.
I suspect the champagne yeast is fine in acidic water but not in basic water for brewers try to acidify their grape juice before brewing to keep bad bacteria from growing and spoiling the wine. OTOH, bread is often made with baking soda and the bread yeast is fine with that.
You ought to see some small amount of foam almost right away. Actual bubbles in less than an hour. If you do not see anything in the bottle, then your yeast may be bad,or the water temp may have been too hot and killed it.
If you see foam in the bottle but no bubbles going into the fish tank, suspect a leak somewhere. Check all connections. I was sucessful fixing leaks using Liquid Nails (clear caulk like stuff from hardware store) on the outside of connections that were actively leaking, assuming they are totally dry of course. You may want to clean an area with alcohol if it is damp.
