Yes I did say that. I was refering to the Crushed Coral...You can add live sand to seed the other sand. Probably 2 to 5 lbs will seed a 50 gal
nicely. Get sand from an existing tank and not out of a commercial packaged product such as Arag-Alive. It is hype IMO
. I do not use anything other than water flow. The wet/dry is just there for now, tho house the skimmer and return pump. It also provides an increase in the amount of water to the system. You can use the sponge in the wet/dry however, you will need to clean it out daily and that becomes cumbersome after some time...I use the sponge only for a catch for the output of the skimmer, for a bubble catcher. Other than that, it is free flowing water all the way through. The key to keeping the detritus and stuff from collecting is have at least 2 to 4 PH's in the tank to keep water moving in all areas. I have yet to acheive this, but still working on a new design to make it effortless. Another thing is, to have as many cleanup critters as possible..The Astrea and Mexican Turbo snails eat algae good. Astreas cannot right themselves when they tip over, but Mexican Turbo's can. Hermits are good also, but to many can create a war in the tank and some are very destructive.. Red Legged Hermits are recommended because they are good algae and detritus eaters and are somewhat docile. Blue Legged Hermits are somewhat pirates and will sometimes take pride in hunting down a good snack and munching a snail (Astrea) to get a shell out of the deal...They are also good cleaners.
The key IMO
to a good reef is:
1.5 to 2 lbs LR
4 to 6 inches of Aragonite Sand (sugar size)
Good water flow
Good cleanup crew
Good Skimmer to use when needed ( I don't use mine all of the time. My choice)
Lighting at about 8 Watts per Tank Gal
size. e.g. 55 gal
= 440 watts light preferably MH
A lot of reading, talking, listening, experimenting.
Happy reefing/ fish keeping!
