I'd recommend using a power head versus an air bubbler for better mixing. As long as you mix for 24+ hours and match ph/sg
/temp to the main tank your doing fine.
Personally I use a 32 gal
trashcan dedicated to mixing SW
and use a Mag 9.5 pump
to mix it up and it also heats the water to around 78 degrees. Then I just hook up a 20 ft hose to the end of the pump and fill my tank back up.
of 90 is pretty decent for tap as most tap around the country is 200+ TDS
. Still using an ro
to get it to 0 TDS
will go a long way in keeping your water as pure as possible.
Not sure I understand what you're doing. Taking the tap and mixing salt into buckets is still "taking water directly from the tap" either way. How have you been doing pwc
for the last year on your 90 gal
