I think aquaforest is the best and easiest to use right now in the market ... for about 6 months I have used all of its product line, with "reef salt", my only complaint and it is something that worries me a lot, it is That in my stones there is a kind of algae, not green, brown, it is something like a thin layer like velvet, light gray and about 1/4 inch, the curious thing is that I have never been able to remove it even in my Water changes about 30% each 2 weeks, I try to remove with a brush and nothing I get there ... I use kessil ap 700 at 30% and 2 t5 as a supplement "ati blue plus and actinic 39 watts" But that achievement is when I do not use the t5 light, I see that this algae decreases ... my parameters are alk 8.1, calc 440, mag 1400, salt 0.26, po3-0, po4 0.02 <0.08 and my temp, 76-77 fy I add as they say np pro and pro bio, af build, af energy, af amino mix and af coral v each second day with light off ....

So the corals look good, I have never lost any, I still think they are adapting to this new environment, it was a new system 75g
