Wondering if anyone could help shed some light on my situation. I have a 30 gallon trash can ( covered) I store my ready to use salt water in. I typically keep it in there about 2-4 weeks ( depending on how often / much I do my PWC
). I use RO
water, and I have a TDS
so it's pretty pure. I have 2 heaters ( its below freezing here now) and a small powerhead ( about 150 gph
) in it.
Tested the water from the ro
directly and it came back as 0.
Oddly enough, went to go do a PWC
today and looked inside my can.. theres a velvety looking light brown / gold 'dust' on the side of the can. Is this diatoms? If so how could this be? I'm a bit confused. Things seemed a bit ' slimey' to the touch too. Maybe is it something 'sneaking into' the can ( eg: lid isnt tight enough?)
I'm battling still a bit of hair algae in my main aquarium and want to make sure I have the purest of water..
any ideas would be great!
