I used the h2o salt for like a year it was good not great ,and half the time its not available in stores if it is its a lot of $$$ so I'm making a switch to ESV seen some tanks that run on esv and I must say it does the trick from what I saw so far .
Bro! ESV is in Hicksville I believe. Check it out in person. Also, BulkReefSupply is selling a bucket of Red Sea Coral Pro for $45.99 on sale right now if you ready right away.
