Looking for some opinions or your thoughts on tank cycling following a rescape.
I have a dirted tank capped with BD blasting sand. It has been four years and I'm ready to remove the substrate and swap it out. The tank scape and plants have been neglected for a bit after my CO2 ran out a bit ago and it's time to start fresh.
*Note; I haven't chosen a substrate but if I go with a nitrogen releasing one, does that change your thoughts?*
The plan is to move the livestock and a couple plants to an empty 30g with the existing filters for a day or two while I rip down the 75g tank and rescape.
When the main tank is full again, will the media in my filters be enough to handle the bioload or will I need to run a good full cycle again before putting the fish back? I know that by chucking the substrate and some plants/rocks I am also tossing the good bacteria. Am I getting rid of too much to for the mature filters to handle it?
Here is my setup to help form your opinions;
I am over filtered with a SunSun304B and a fluval F6.
Fauna: 1xAngelfish, 3x turquoise rainbows, 3 SAEs and 8x red tetras. I will be adding to the livestock when the tank is set up and good to go.
I will only be transferring my Java fern, some crypts and my 2 swords, all other plants will be new, not sure if this influences your choice.
Thanks in advance for your time in reading and responses!!
