Live rocks in freshwater tanks.

[Jamescain31]

Ok, I have been searching and asking more than I would like to ask one question. I am not a beginner, it's just been so long since I have had a tank. My first tank was a 10 gallon, with RTS, Tiger barbs, and red eye tetra's. My second tank was a 125 gallon coral tank. I'm going with a 75 gallon for my first new tank. I want to use as much living organisms as possible. I was wondering if there was any particular live rocks that can be used in freshwater aquariums that will support living bacteria life?

You can use DRY rock. The bacteria will colonize on any/most surface once it starts to grow. SW type rock is porous and will provide a ton of area for growth. Be sure its been dried out for a month or so and be sure to rinse it well and it would not hurt to get a vinegar bath either.

Thank you

I have to say this is the best result out of at-least 7 other sites. I have been trying to find the best ways and most effective ways to build an environment fir bacteria colonies. I am going to be using this item to place under the top soil and gravel for a more sufficient production of bacteria colonization. I am going with mostly live plants, drift wood and I was hoping to finding a particular live rock. I will research into the dry rock and see what I can find. Thank you very for the information.

CerMedia Marine Pure Biofilter Media 8x8x1inch Plate - The Aquarium Shop Australia, this is the item I meant to put in my last post.

I am not sure how well it will work if under the substrate. nitrification (nitrogen cycle) happens in the water column for all intended purposes. Sure there is some anaerobic stuff that happens but thats not what you are talking about. Its really only going to work if you have it in the water column.

I have order a canister for 100 gallon, and a top filter for a seventy five. Would it be best to place it in the top filter where the water overflows into the tank?

I would have them enter on opposite sides of the tank and be sure to set them so they made good ripple on the water surface as this is how the water get oxygenated.
