Upgrading from 70 gallon to 105 rimless

[Arnaldo24]

I did 3 upgrades last year, everything done the same day with a few more than 8 fishes and i dont think i run into any problems. Adding 30 more gallons of ro salt water is like doing a big water change to fix any problems. Is not like u upgrading to a 200 gallons

I disagree.

If he adds no new rock and just new sand, it would barely if anything at all cycle. And if it does, he can just do water changes to keep the params stable during it. you could even add extra bacteria if you really wanted.

Selling all of his fish/coral or removing them is silly. He has 100+ pounds of mature live rock, that is plenty to start with in a 105g system.

+2. Every upgrade i did i change my sand with no problems

Do NOT add any of those 'instant cycling' products - they all contains a large amount of nitrites - and you definitely do not want to add additional nitrites to your tank!

Not to hijack, but he moved his stuff already anyway. But does it really? I cycled my 120g from scratch and around week 2 I bought a bottle of some brand I forget the name and dosed the whole bottle. Cut about a week or so off the cycle and my nitrates were steady.

Is it just bad brands or all of them? (For future FYI)

Alright so i moved about almost 2 weeks ago and everything is running and healthy and i didn't lose anything. i even moved the sand from the the old tank and added 40 more pounds
