I hear mixed opinions, but went this way due to the volume of solution I am dosing while the lights are out. I have been slowly ramping up each night. Think I am now around 1500ml from 8pm to 8am. Comes out to 26ml every few minutes.Scott - so sorry to hear about the cracked CaRX! Bummer!!!
Recently added a doser Kalk solution to also get pH higher. I’m just using a 3 gallon jug with 2 tsp of Kalk and dosing 20 ml throughout the day. Wondering if Kalk stirrer would be more effective?
I got the Reef Octo 250 which is about 6.5gallons loaded with 180grams of KALK. I have managed to raise the pH floor to just under 8. Still figuring it out, honestly. I have to go slow and keep checking my ALK and adjusting the 2 Part dosing as well.
