Ok I have a 20 gallon tank and I used conditioned tap water. Real ocean sand that has been kept wet. I have diatioms. my reading were
ph-8.3
am-.25
ni-0
na-5
sg-1.025
Does this mean that my tank is cycled it has been about 20 days since the beginning. I didn't use shrimp or a fish to cycle, it did it, itself.
does this make sense.
