Hello, I started my tank cycle already but failed to put a divider in yet. I read the tutorial that was posted on here that you have to use aquarium sealant and all that.
Since I already started my tank would I be able to just take more water out when I do my water change before the fish go in and do the divider tutorial like that? I would take out most of the water and keep about 3 inches in so the rocks don't dry out (that's where the benefical bacteria is right?) and I would let the filter sit in water so that doesn't dry out too.
The divider would still go down all the way it just wouldn't have the seal on the bottom 4 inches.
Would this work? Then I would just fill it back with pre-treated water, test the water again and then pry let it sit overnight so the water could heat back up.
Please let me know if you need anymore details. I have a 14gal tank.
