Cycling Quick??

[Holmez221b]

I currently have a 55 gallon tank with a 30 gallon sump. I only have 2 fish and a green brain. I'm upgrading to a system with 205 gallons of water volume. I need to do the swap pretty quick , so this is the plan. Let the larger system run for a week, take 85 gallons from the new system and replace it with the water from the old system along with my fish and coral... I know this isn't the right way to cycle my tank but I'm under a time crunch and wanted some opinions...

Taking water from one and adding to the other isn't really going to do you much good. Very little of the beneficial bacteria is in the water.

You'd be better off taking any LR you currently have and adding it to the new tank. Take a coujple cups of sand or substrate from the smaller tank and add it to the larger. This will be enough to seed the new tank with bacteria that your over-all cycle time should reduce to a week or so.

Sounds good... I thought the water might help the fish and coral
acclimate a little better..

It will help. It certainly isn't going to hurt it at all.

Just not going to help with your cycle.

I used 20 lbs or so LR and 2 or 3 cups CC from my 29 when I set up my 92 and it cycled in about 3-4 days.
