I decided to test RO
water with instant ocean I had mixed the other day before doing a water change. It has been running in a bucket with a small powerhead and a heater.
I was kind of shocked to see the following results with Salifert test kits:
I guess this explains why I have been struggling to keep my calcium and mag up, eh?
There is probably the possibility of a bad batch, but I'm curious if any of you are using a higher "quality" salt mix that has starting calcium/mag/dKH
around what one wants for an SPS
reef? (~450-500 calcium, ~10.5 dKH
, ~1400 Mag)
I don't care if it's more expensive than instant ocean, as I figure I'm paying around $2 per 5 gallon bucket of water (1/4 bottle of seachem mag) to get mag where it's supposed to be. That and I'm tired of making sand when dosing 2 part due to the stupidly low magnesium I'm constantly battling.
Thanks in advance!
