thanks,Fastuno and Zig. it's funny every time i see people worry about 9ppm coming out of their RO water. I only use RO and no DI. the water that comes out of my RO is 10ppm from 220ppm coming in.
I don't use Refugium. my sump still have Bio wheel. no dosing just 15 gallon weekly W/C. what I learned in reefing is keep it simple. never ever panic.
Very healthy & colorful chalice. When I fed Cyclop-Eeze YEARS AGO my phosphates & algae started to bloom. Drop the feed back down & all was good at that time.
It is interesting how you can go changing 15g/week & another dude comes in & does something totally different. Both systems seem to suffice & result in a healthy tank.
Look at 28:00 into the video & newyorksteelo will say he did not do a water change for one & 1/2 year.
