unit is small, most can fit under a sink. How much LR
are you getting?
You can pick up a couple garbage cans and fill them with the SW
from your tank and then place the LR
in them till you get your RO
unit. You will need a PH
in each can u use. You can also do what you want but IMO
it could be some time till you do enough water changes to get all the tap water out. There are people who have tap water that is fine to use and they never have any problems. There are others when you listen to there stories it can give you nightmares. Its a crap shoot could work out fine or it may give you problems. Adding the LR
to the tank as it is IMO
will not kill the LR
and make it useless. Its a tuff call, what ever you do just don't leave the LR
out of water for too long after you get it.
