Seachem's pH 7.0 Neutral Regulator works well enough,
but the reason most planted tank keepers don't use it
is because is adds a lot more Phosphates to your tank
water then your plants may be able to absorb, which
could in turn encourage an algae bloom. this is why
most here use common baking soda to moderate pH.
so I would only advise using that Sechem product if
your tank was low light, and did not already have very
a very high phosphate reading.
