he he this ones interesting....
I used to keep a 32 gallon brute handy with a powerhead and heater dropped in (along with a pump to the
sump for nice fill automation during water changes) up until last weekend (Switched to a 25 gallon rubbermaid). Since I do 2 * 5 gallon water changes weekly (thursday and sunday) the 32 would hold 3 weeks worth of
SW, I switched to a smaller container originally because the brute sprung a leak and well... heres the other reason!!!
By keeping my W/C water heated I could introduce it to the tank without fear of heat shock... originally I had this heater switched and would kick it on the morning of each water change but decided to let it run all the time... silly me. Imagine my suprise when the
salinity of my water change source jumped way up!! If I didnt have a habit of checking it periodically I would have never noticed... one week of heat and it had evaped out quite a bit, so smaller more airtight and sealed container (less water standing) and heater back on the switch for me. Routinely refilling it every two weeks is still not a large deal and plans are in the works to plop an
RO feed into the tub with a float switch (and a master valve) so that I can mix the salt and such all in one (right now I pre mix in 5 gallon buckets and pour in).
Regardless I think
SW sitting for a short few week period is not a huge ordeal, the biggest problem I see is evaporation and
salinity change!
