I personally wouldn't trust the place that offers their own premix here. I have my own RO/DI unit -- saves a lot of lugging around, I wouldn't even consider it as I go through about 4 gallons of topoff a day.
+1…When I first moved to my mother’s house…her water was so bad I couldn’t even trust an RO unit to clean it up..the filters would clog up in a few weeks. I had to lug 48g of water every 2 weeks to keep the tank going…I have since moved and have my own RO unit…sweet bliss!
My LFS sold premixed, they never got my numbers right…I landed up just getting the highest amount of SG they sold in premixed water and added the RO water I got from Wal-mart to make it right.
I had hair algae when I used their water as well, so I don’t think it was a very good place to get my premixed. However if I had an emergency like a leaky tank…I at least know where I can get some water in a pinch. So I won’t write them off completely, they are just the last resort.
