upgrading to a 75g

[SaltSolutions1]

I decided to upgrade from a 45g to a 75g. If I put everything I have from my 45g into my 75g will the tank still cycle or can i just add livestock right away?

It will depend on what else you add and the shape it's in. If you add more live rock, depending in the shape of that rock, you could see a cycle. If you add or replace live sand, you could experience a cycle. I would recommend replacing your live sand. Using your existing live sand poses the danger of lots of nasty stuff being stirred up while removing your old sand. There's all kinds of nasty gasses and such just below the surface.

More information will be needed about your plans to accurately answer your question.

Here's the full plan. I like tangs and I cannot keep them in my 45g. In the 45g I have lots of coral, a lawnmower blenny, 2 percula clowns, 1 dragon goby, 1 six-line wrasse, 1 flasher wrasse, 1 decorator crab, 1 sand sifting star, a cleanup crew made up of snails and hermits. sand bed about 3" and 75 lbs. of live rock.

In my fuge (10g) I have a 3" substrate made up of miracle fuge mud and live sand with cerith snails and hermits.

I found a guy locally that is selling a brand new 75g tank still wrapped up in packaging for $125.00

It is not drilled but I thought that for that price it was worth it. Please correct me if I'm wrong. I have not purchased it yet.

I have my 10g drilled now flowing back into my 45g now with a pump pumping water back into the fuge. I was looking to do the same thing with the 75g.

If more info is needed let me know.

Please advise as to whether I should proceed or hold off on this $125.00 deal and please advise on setup options.

Oh I almost forgot:

I plan on using the live rock in my 45g to seed base rock in my 75g.

In other words I will buy base rock and fill in the 75.

well the base rock will still need to be cured just like live rock so there may be a cycle from that. There are still organics bound in th base rock even though it's dead.

You won't notice much from base rock if it has been kept indoors or in a sealed container. If it's been in someones back yard out in the grass you may have some. But I think you'll be fine. You'll no doubt have some kind of spike, but I imagine it wouldn't be that severe.

Can you just keep both running for a week and only move over the non-encrusted live rock? After a week move the fish and coral encrusted rocks over?

I think 125.00 is a good price for a new one. . I bought a 75 gal with stand used but looks brand new on craigslist here locally for 200.00. Also, recently I converted from a 55 gal. to a 75 gal., transferred everything including water and didn't experience a cycle. I used my old sand but only had 55 gal going for about 5 months and didn't have an abudance of livestock. I did get varying opinions on using old sand or not but I went ahead and used. I drained 55 putting water in large clean plastic storage bins, then filled 75 gal up with about 2 inches of the existing water I saved. I then tranferred sand over. Then laid clean garbage bag down on sand to avoid stirring up water that I transferred from 55 gal. Then, I added new water for the extra 20 gal. that was short. Anyway, this worked for me. Btw, after transferring everything I waited a while before adding my livestock back in, wanted to give a chance for water to be filtered a while first. Had fish in large plastic storage bin with existing water with powerhead for circulation until I transferred them to new tank. None of my livestock died.

will a 10g fuge and a cpr bak pak 2 HOB skimmer be enough for a 75g tank? It is not drilled so I will be setting up the 10g which is drilled to drain into the 75 and pump water back into the 10g from the 75 with a pump.

Well it is kinda underpowered but works, i recommend at least a 20 gal refugium/sump and an in-sump skimmer. my thread should help you out (the little red house) though ignore the fish

Your setup looks great! Congrats!

I understand the benefits of a larger refugium and even a sump.

Here's the dilemma:

I have limited space to work with as the 75g will be sitting on top of a dresser and not a stand with space under it for a sump.

I have a 45g on a stand and a 10g sitting on the dresser now. I have to build another stand for the 10g so I can get it to sit next to the 75g and drain into it by use of a bulkhead. No other options as my fish room is also my bedroom.

any other suggestions now that you see the limited space I am working with?

I have a 10g fuge
a 45g reef tank that I am not sure what to do with...... I was thinking of using it as a QT but I can only fit probably one more fish (a tang) and that is pretty much it in my new 75g if I add the fish I have in my 45 now so it would be a waste.
I also have a 10g tank that I am not even using right now.
add the 75g that I want to slap on my dresser and I am looking at a jam packed fish room.

Please help with some ideas.
