i use a lot of macros in my predator tank but they also need lots of attention trimming and such , they help cut down phosphates but there's always a detectable amount
I find phosban to work best in my main tank , if you don't mind the extra work macro's will work but need constant attention as they grow fast , macro's are also a good way of telling if your water chemistry is out of whack , so it can be corrected
but if your new to
sw I would recommend a reactor over macro
once you get more comfortable than take on the macro challenge
this is a macro tank I had a while back before I upgraded
lots of work and constant attention helps for a healthy macro tank
