ok i have a 10 gallon i'm trying to setup as a nano, what i want to do is add about a 3/4 inch of crushed coral, but it's like the crushed sea shells about the size of a bean. the company that makes it is caribsea, it's called seaflor, it is marked puka shell. it claims to be high in magnesium, and strotonium. so what do you think about 3/4 - 1" then a sugar sized arag. sand? is the puka shell a bad idea?
I am using the same stuff as a substrate in a 1 gal pico reef. However, I am use to using southdown here and I am about to tear down the pico reef and rebuild it into a 3 gal nano reef with southdown. (Basically having a hard time maintaining flow and I guess prefer having the option to have a power filter)
ok for lighting i'll have 4x13 watt cf, 1x18" no atctinic 03,
1x18" no 50/50, for a grand total of 82 watts for the 10 gallon. in case i didn't explain myself clear enough, i'll be adding 3/4 of an inch of puka shell, then i will be covering up the puka shell with 8 pounds of sugar sized sand.
