live rock. FYI im not really new to reefing

well i just wanted to know if a tank done with its nitrogen cycle still needs 1 pound of live rock per gallon and if it needs any at all:helm2:

 

You want to leave your LR in there for filtration. That a a good skimmer is a must!

 

but can you put less

 

You could, but actually closer to 2 lbs per gallon is best NOT 1.

 

so with a fifty gal how many after nitrogen cycle

 

i don't subscribe to any "per gallon" rules.

put the amount of rock in there that looks good to you. LR is the best filtration, but don't think that if you don't have exactly 2.0 lbs per gallon of water (or 1.0) that everything will die.

 

well im just gonna have to make a diy sump

 

any saltwater tank should have a sump

 

its not necessary tho

 

Although I don't subscribe to the per gallon rule, I do believe the more LR the better. If your not comfortable with 2 lbs per gallon in your display tank then add the rest to your sump.

 

if im gonna have a 20 gal sump for a 50 gal tank how many gph

 

It helps on the oxygen issue. The tank surface, the skimmer, and the sump all help the gas exchange. The salinity in the salt water make the water harder to get oxygen than the fresh water. That's why sump is usually recommended.

 

If it's done with the nitrogen cycle, be very careful on added not-so-fresh live rock though. They could cause another mini-cycle.

 

The porous in the live rock provide more space/surface for the nitrifying bacteria to live in. Hence, more the better. You can go without no live rock and just use whole bunch of porous man make material in the sump or any where to provide the same benefit. They just don't look as good.

 

Are you not going to have live rock because you are going to get a cuttle fish??

 

the cuttlefish is going to be hard to look at with all the liverock i have rite now but im going to have a few pounds

 

i called it lol

you know they have short lifespans and some of them get six feet long :shock:

 

oh you dont need to worry about my knowledge of cuttlefish Im know alot about the care of themand only common cuttlefish get big im gonna get dwarf

 

awesome want pics asap!
