Hello all,
I'm in the process of curing LR for my FOWLR and recently performed an
ammonia test. The test (new) only goes to 8 ppm and in less than 3 minutes,
the test sample showed at least 8 ppm. Due to the size of the tank and the
rate of my RO, a quick 50% water change is somewhere along the lines of 10
days when you consider saltinity conditioning and temp adjustment. I
currently have a 100 gal reservoir for salt water prep in the garage and
have been conditioning water for a good LR scrub down (there's still a lot
of dead growth on them) and will be ready in the next two days.

My system is set up for small simple water draining and was I considering a
daily purge of system water and let the attached RO refill the tank. This
is about 12 gals a day but I know the salinity will slowly declline (~280
gal in circulation for a 240 gal display tank). I was considering preparing
concentrated salt water to periodically add to the system water while I
perform the daily water changes. I figure that the salinity range would be
no more than .002 as I make these adjustments.

Any thoughts on this proceedure? I'm concerned about loosing too much live
organisms on the LR due to the high ammonia and given the time frame it
would take to reduce the level at 12 gal a day, that can take a long time.
Once I have the system stabilized and stocked, I thgouth this would be a
great way to do more frequent maintenance water changes.

Thank you,
Justin
