Any thoughts and/or suggestions about trace element replacement? Are the replacements with Instant Ocean every two weeks with water changes enough, or should I add more? I do add Calcium regularly. Two tanks, 30 gal with fish, inverts, xenia, live rock, and a 90gal with fish, live rock, and shrimp. 90 gal has protein skimmer, 30 gal does not. Thanks for the input.
