6" DSB Fuge to be transported.

I'm transferring my 120 Gal reef tank to a 210 gal tank. The 120 has only been setup for less than 3 months. I know I'm crazy already but I have some questions. I have a 6" DSB of Caribsea Oolite and I have cheato, live rock and some red slime and hair algae in the fuge. If I dig all that sand out could I find some pockets of nitrates that could kill inhabitants in my new tank. Should I just pull out a few cups to seed the new location and add new sand? Should I forget about sand and rock alltogether and just have cheato? I'm going to be transferring all my equipment to the new tank so there won't be too much of a change in biological filtration. My RM300 sump and Marine Pro 300 skimmer are designed for a 300 gal tank. With the 6" of sand in the 12"x16" fuge that's part of a 36" sump that's about 45 lbs of sand, it might be too heavy to work with and get it out of the stand and into the new one.

Just a little concerned with that red slime as I saw under the sand in my display tank a red coloring. I got in there with a cleaning stick to clear it out. But still worried a little. Any ideas out there?

 

Wow that new tank looks really nice. Is you refugium and sump seperate? If they are, then you could move everything over and just run your sump. Hook your new refugium up, but leave the intake off, and the return. Just just give it a few days so the chaeto can obsorb any of the nitrogen that has been trapped in the sand. Or just go with new sand and move your rock and chaeto over. The red algae isnt bad in your refuge, as long as it isnt in your display tank.

But you should create a thread about the progress of your move and post some pics, I hope it goes well for you.

 

The sump and refugium are together and I can't run the sump pump without water running through the fuge. I don't think I'm going to take a chance and just get new live sand and seed it with sand from my display tank.

 

Thats probably your safest bet.

 

Yeah I think that's the way to go. Do I need 6 full inches of sand?

 

Anything over 4" is considered a deep sand bed so you don't necessarily need 6".

 

I wouldnt think you could have to much build up of any nitrates if the tank is only 3 mo old. A new tank already. You have got it bad.

 

I have a 4" sand bed and I have read alot of posts that say anything over 4" is kind of over kill.

 

I've heard that too I just didn't want to take any risk.
