my tank is sps/lps dominated and i use seachem reef salt and natural salt water. Water changes are not just for trace element replenishment, its also a way of nutrient export.![]()
The salts I have had the best results with is Tropic Marin Pro Reef and HW Reefer. I have also used Coral Life is good results. IO is crap, low Ca, ph and alk. IO Reef Crystals is good on Ca and alk but has a low ph and potassium. I think I will be going back to Pro Reef or Reefer.
I use SeaChem - pretty good levels so I don't have to dose as much, it's readily available in my area, and there's usually a group buy or sale going on. After experiencing low potassium in my tank and losing several corals to it while using Reef Crystals several years ago...I realized its a bigger issue than I first thought.
Thats not true Pro Reef is perfectly balanced and very consistent. I have been using RC for like 2 years now and have never been happy with it. But it is less costly. So I think I have been using the same salt for long enough and my parameters are very stable. I was referring to IO and RC be low when freshly mixed. I would rather have a salt that is ready to go and worry free once mixed and needs less dosing. I only have a buffer and Ca for doing when I used Pro Reef or Reefer. Since I have been using RC I need to dose iodine, potassium and strontium to keep sps colored up.No salt is perfect and is exactly hos we stated earlier...Stay withe same salt and weekly/daily changes and you will figure your tank out. Sounds like you need to stick with one so your tank can become a little more stabe.
