If all goes well, it looks like my wife and I will be buying a new house. :D One of the biggest task in the upcoming move will be to move my reef tank. I have never moved a tank so I am sure that will be adventure. Any suggestions on this are appreciated.
However, my main question right now is about my sand bed. I currently have a plenum system set up which is uses about 4" of 2mm sand. Functionally the system seems to work fine but I not really excited about the look. The lower 3" is a mottled green-grey color. The top 1" is white with a some grains being green-grey. The grain size is pretty chunky. I have also heard of older plenum systems crashing due to some form of sulfate build up. Plus plenum system are not very popular so it is hard to find info or opinions on them.
So, my question is would it be a good idea to change over to different type of sand bed and if so what type. I know I don't want bare bottom. I really like the look of white sugar sand like Southdown. What are the pro and cons of shallow sand bed (1") versus deep sand bed (4")? If any one has good article please point me in the right direction.
It makes sense to me, to change the sand bed when I move it but is there any danger in this? I have a large amount of seasoned LR in the tank (approx 100-120 lbs) and a low fish count (3) so I think the biological filter will be fine.
Any ideas, suggestions, or opinions are welcomed.
