I think the biggest advantage to doing water changes is replacing trace elements. For people using calcium reactors I doubt there is much value. For those of us who dose 2 part, we either need to do water changes or use trace element supplements to keep them up. It may not be a problem for a few months but I would worry about it longer term.
I don’t use a calcium reactor (seems to complicated for my brain and looks like a bomb! lol) but i do dose the foundation elements daily and the trace elements are replaced via Red Sea Coral Colours so basically everything needed is re added as it’s used up. And most bad stuff is removed with the skimmer, activated carbon, Nopox, rhowaphos and Purigen. So hence my thinking.
No waterchanges unless there is an emergency, 3 years 4 months old, I don't see the point!
2 heaters and 2 return pumps, oh and 2 refugiums, because they told me I couldn't do this!
Precisely Simon! Lol
It probably will be the long old debate for years to come so ‘you makes your choice’. The mixing station is on!
