Hi, I’ve a 130 litre tank and changing the plants in there with some redwood. I have fish already in there and wondering if I need to do daily water changes to prevent algae and anything else to make sure it goes ok!
Good idea.Last question would you recommend adding 20% of my old aquarium water back into the tank and the rest 80% of fresh water?
There aren't many in the water column itself, there are many more in the attached biofilm on plant roots, in the upper layers of the substrate and on the filter media.Don’t want to get rid of all the good bacteria
