Tank Upgrade Strategy?

I'm upgrading my "show" tank from a 72 bow w/ a canister to a 210 with a sump

My 72 *seems* to be doing fine, but I'm worried for a few reasons for moving the water, sand and rock over to the 210.

1.) I have a couple flatworm outbreaks. I used Flatworm Exit to help with the problems. All appears well right now.

2.) I get what I think to be too much red slime. I think this is a combination of my diminishing clean-up crew (cc star is about 6.5" and hungry) and source water quality (I do not use RO/DI).

3.) My current live rock has plenty of activity and life, but it seems to have developed some redish carpet-like algae.

4.) I've not used RO/DI and am reluctant to move that water to the new 210.

5.) The two "show" fish seem a bit timid due to their size (mostly the reason for the upgrade) and not having the proper room to swim.

The upgrade is fairly substantial. In addition to the 210, I'm moving to a decent sized sump, an AquaC EV400 skimmer w/Mag 24, a 60 gpd RO/DI system, Solaris 20K LED lighting, a Dolphin 4800SP return and a Dolphin 7500 Amp Master for my future closed loop. All equipment (except the 210 and lighting, of course) will be located in the basement-- thus the larger pumps. I'm using flexible PVC for all piping where appropriate.

Now here's where I need some advice...

Should I start "fresh" in the new tank with all RO/DI and new cured live rock and new sand; or should I move my water, sand, and rock over?

All additional rock will be coming from coralreeffarm.com, which apparently is fully cured with decent shipping practices to avoid die-off.

In either case, I'll be upgrading my 54 to the aforementioned 72, so some investment will need to occur during that process as well.

I'm just looking to accomplish the upgrade in the most efficient manner possible, with minimal stress on my fish.

Any advice will be appreciated.
 
zenkick,

Personally, I would start fresh in the new tank. There is really no benefit by moving your old water. You will get all you need from your LR and the new LR. If you can, get the new tank set up first, put in your new rock and slowly move your old rock (if it's possible) If you don't see an ammonia spike after the rock has settled, move your livestock.
 
I wouldnt use any of your old sand either as it is totally disgusting when you go to move it. I would just take a little bit of it to seed new sand. It is definately better to have the new tank up and running and "broke in" before you move everything over. HTH
 
Thank you both for the advice. I was leaning towards the fresh start and obviously *not* rushing the move.

Now I just need to build my rock scaffolding and pick out some sand.

I'm thinking of utilizing some of the pvc scaffolding as return jets for my closed loop. Anybody have any experience with this?
 
no experience with pvc scaffolding

but penductors (i know thats not what their called... could someone correct me) are popular.

their like a little nozzle that goes on the end of pvc or loc-lines that help spread out the flow
 
If you had issues with your old tank (red slime, etc) maybe consider going barebottom on ur new tank? then, you can really kick up the flow. Besides, the bottom of the tank will cover nicely in no time with coraline and zoas, shrooms, etc... just a thought. I will be doing a similar project this summer, and plan to go barebottom, as I had an issue with cyano, and the sandbed is more trouble that its worth. I should mention that my tank is and will be predominantly SPS, so I need it to be REALLY low in nutrients, etc... with LPS tanks, I would keep a sandbed. JMHO!

I have a couple 3/4" female penductors....they do need to be run on a pressure rated pump. I like the idea of the scaffolding but did you ever think of using a masonary bit and drilling 1/2 in holes through the rock and using pvc pipe to stand them up? I did this and it allowed for a rock wall that didnt have to rest on the back of the tank...HTH
 
Yes, I thought of that after reading some suggestions on aquascaping-- building a base with a pole going up the center and stacking rocks on it. In this case the base is just to keep the rock off the bottom, of course.

I may do both. I haven't decided yet, and am in no rush-- even though my massive order arrives tomorrow and my tank stand should finally be in.

Must... resist... urges...
 
I have a 90g that I got about three weeks ago and it's still empty. I was in rush mode at first when I brought it home. Now I'm slowing down. My 50g is less than 3 months old. It was established for 2 yrs when I got it but I still went through algea blooms and now trying to stablize the water quality. Too many swings in DKH/Calcium. No more live stock until I get this figured out. And I REALLY don't want to jump into a larger system and have much larger issues. So it can wait. It just sucks seeing it sit there.
