Hey guys,

My tank is fairly new, about three months old and I've noticed I'm getting some pretty significant alk swings. I been raising it with baking soda slowly, but it depletefrom 9-6 DKH in 2 days or so. So instead of dumping baking soda in there every two days i corrected it to 9 and want see if KW in my ATO will help stabilize my levels.

Mag- 1400
Alk-9.4 dkh

My question is regarding how the kalk/RODI water should look before uits ready to go. I'm using 4 tsp per gallon in a 5 gallon bucket. I mixed it in and let it sit for about 3 hours. Now it looks like it has a thin film on the top and the water is not clear. Is this how its supposed to look before i plug my ato back in?
