I am wondering about my circulation in this tank. I have approx. 950gph flow between the two Koralia nano's (I replaced the MJ400 in the picture) and the return pump (Quietone 3000 through an SCWD).

Does everyone think this is enough flow for a 16G SPS dominated tank?

that is like 60x turnover... I'd say that is plenty for SPS.. :mrgreen:

Ok, thanks...I look at the water column and it just doesn't seem to move like my 70G so I couldn't help but wonder.

I'm not sure if a Quietone is pressure rated or if the SCWD can handle the back pressure, but you could always try the enductor I made last year when I was bored. If you are interested, I can drop it off this weekend. It's just sitting in my workshop collecting dust.

Cheers

Hey Kevin, that would be great. I will check into whether it's pressure rated. Feel free to drop by, we'll be in and out all weekend.

I'm not saying I'm ready for sand yet, but I was wondering if you had suggestions on the best way to put the sand in now that the rock formation is built? How do I keep it from clogging the rock up?

I put the seeder rock in today...if I don't see any cycle in the next few days I might just try to put the sand in.

Put the sand in a cup or bowl (after it's rinsed if it's dry sand), then gently lower it to the bottom of the tank and gently dump it out. Your tank will still get uber cloudy though. Use a turkey baster to baste rocks 2-3x a day.

Since you are using Eco-rox and just a small seeder rock just put your sand in.
Usually when you cure your rock in your tank you get allot of die off that settles on the bottom. It is easier to remove it without sand.
You won't have this problem because there is nothing to die off.:wink:

Ohhhh yaaaaaaah, I forgot you were using EcoRox. I agree with Marlin.

Well thanks to everyone who said...."get that sand in there" as I was itching to put it in.

It's Fiji Pink Live Sand so hopefully it will help get the Eco-rox going along with the two small pieces of cured liverock that I put in there already. It ended up being about 2" all around the outside...but that will slowly lower as the sand works it's way into the center of the rock formation.

Here's a pic of the sand just after I put it in:

All the rocks have been blown off and I'm hoping that it will clear up over the next 24 hours or so. Any suggestions for removing the scum off the top of the water. I really don't want it going into my sump because I know how pick the SCWD's are and this stuff will kill it.
