Hey Smite, how much do you dose a day and how big is your tank? Mix reef?
Yeah right now it's pretty much a mixed tank. I had a few metal issues and lost a lot of stuff and pulled my calcium reactor.
There was a local reefer who had some of the nicest sps I've seen in person, Mr.V. He swore by ESV 2 part and also their salt when I was at his place.
I started ESV about a month or two ago. System is 210 gallons. So far I'm only dosing 50ml of alk/calcium daily. It's keeping my big 3 @
9 dkh
440 calcium
1450-1500 magnesium
The ARM media in my calcium reactor really raised magnesium levels for some reason, ESV has just maintained them there so far.
A good amount of my acropora are still pissed (but new additions happy) but my LPS and some of my easier sps pieces are growing pretty well. I have coraline algae like crazy so I'd say ESV is doing a very good job. I bought the 5g tubs, it was a pain in the butt to mix the alk but the pour spouts are awesome accurate.
For two part I really like ESV, long term history of being reliable and consistent. I'm not sure if you get them shipped but they come half full for shipping costs. Same when they go to a LFS, so if they filled them prior to selling, stick to somewhere you trust the water source.
