Upgrading a tank for the first time how do I go about it? What do I need to know

[Dendro Dude]

If Im using my sand and live rock Will I need a full cycle? Going from say a 29 biocube AIO to say a 35 gallon with a sump so probably an extra say 25 gallons of water? Will I need to temporarily rehome? my live stock? I just want to know what I'm a up against any tips would be helpful. Thanks in advance people !

If you move sand, rock, all the water and just add some to make up the difference you shouldn't have a cycle. Use some dr.tims just to help out with the nitrates you'll release by stirring up all your sand.

I think you should be fine. I wouldn't add anything new until your 35 is up and running a bit. \. Just make sure to keep as much of the water as possible for the switch. I recently did the same thing and had no problems. Make sure your testing every day for the first little bit.

Lots of back up water , extra containers for holding livestock, pump/ heater. Get bacteria for new tank

Is there any way you can go bigger? My only suggestion would be to go bigger than a 6g display upgrade. You will be happier and it will prolong another upgrade haha

If your going to add a sump and go tru all the change i would say 50g would be a better option

if u use the same sand ur tank will cycle again, it will release all the nasty stuff burried below ur sand!! i upgraded 3 months ago n went with new sand instead, think its a better option. if u use the same sand ur going to need to wash it

I concur with kam, 6g upgrade is is not going to make an impact. 50g-70g would do u justice for about a year. I would transfer everything except for the sand. When your draining the old tank try not to stir the sand to much and leave bout 2" of water.

I went from a 22 gallon to a 70. Used same rock and some new rock. Used brand new sand. Dr Tim's and everything was fine.

dr. tims is bacteria in a bottle that helps cycle the tank.

you can re-use the sand but wash it out completely before adding it. Why such a small upgrade?

Yea but going from All in one set up to a sump system I'd be getting 26 gallons in water volume 6 inches front to back & 10 inches right to left to my display that's a pretty good amount of real estate. Remember the way am Aio is set the whole back part of the was just for filtration. Plus I live in an apartment & don't want any crap if you get my meaning. I think a 50 gallon cube would get some unwanted attention
