Tank cycling - Moving fish into bigger tank

[BrentE]

Hello, i currently have a cycled 100ltr tank with 1200lph internal filter with proberly 20kg+ of rock. I have a new 4ft 300ltr tank and was just wondering if i transfer the filter, water and ornament rocks (not gravel) from old tank to new tank and add fish straight away would this be ok? I also put another 1500lph internal filter in 100ltr tank to 3 days ago to try and get some bacteria flowing through it which will also go into new 300ltr tank.

Thanks sorry if its confusing lol.

HI Mate,

if you moved all the 100L water and all the rock with the current filter and all the fish, the fish should be fine as it will be the same as massive waterchange but try to feed less amount of food and get some stability.

The thing that should watch is the temp, use safe or prime and slowly add the 200L water to the new tank and ensure your fish already in the new tank when you adding the new water.

Try to be patience to add more fish within a couple week.

I did this few time in my tank

All the best
