ESV 2 Part vs TM All For Reef

[Noodles_Jefferson]

Both methods are good choices.

ESV can raise pH while the AFR will not.

You may want to consider a trace element mix with the ESV since it does not add trace elements against organism depletion, while the AFR tries to do that.

With AFR, you may need alk and calcium solutions on hand in case your tank does not use alk and calcium in the ratio provided, and if demand is low (such as in a soft coral tank), you may want to use a trace element mix with AFR as well.

Thank you. question, if i use the bionic and supplement it with a trace elements solution do i risk adding too much trace elements into the tank. i know you mentioned that too much copper is bad for inverts.
