I agree that sand beds are the topic of conversation and opinions, and will continue to be.
I think its up to the individual to make their own decisions and to research and do what they want to do.
Just because I say it doesn't make it the best way or the only way, Just because
@flower says it doesn't make it the best way or the only way.
Everybody's tank is different, everybody's system is different & the person themselves is the only one who can make the final decision. I mean 10yrs ago a ton of people started putting DSB's in their sumps instead of tanks, I know here it is really popular to have less rock in your tank and tons of rock in your sump. People are staring to realise not that flow is more important in the tank, and less flow through the sump means more efficient nutrient control, who would have thought. .
But as you all know things change in this hobby all the time, sometimes we just have to agree to disagree, move on, I personally think that's what makes this hobby SO interesting and fascinating. . And what works for me may be the totally wrong thing for someone else and visa versa.
