Seachem's pH regulators are dependant upon the unique buffering properties of
phosphate, which works a little differently than carbonate. I don't fully
understand this one yet, but there is a reaction betweeen two variants that
keeps the pH where you want it.

I would wait if you have courage. Don't if you're chicken. It takes more
than phosphate to cause an algae bloom, and that's the only threat here.

If you are sure you need more alkalinity (buffering), then that is one way to

You see, it's all a game. The simplest solution is to pick fish compatible
with the water you will end up with after your tap water sits around, and
then you pump the CO2 in. A lot of fish which the books say like slightly
acidic water actually thrive in pH levels of 5.0 to 6.0 in the wild. Maybe
that's what they mean by "slightly acidic". Some of yourf plant choices may
be restricted also by the lower pH, but they aren't as sensitive as the fish.

All those plants should do fine in acidic water. Don't be so quick to mess
around with chemicals unless you absolutely have to.
