Starting a SW/Reef aquarium

I have three FW tanks.....if/when I start a salt water tank, is there any reason I might not want to use water from these established tanks to start a salt water tank without cycling from square #1?

Yes. It's different bacteria altogether and I'm afraid it won't work.

If you can get fully cured live rock, you may not have to cycle at all. Otherwise, you can fishless cycle using raw shrimp or pure ammonia. If you have uncured live rock, the die-off will start the cycle for you. Also, assuming you use tap water in your FW tanks, it is better to use RO or RO/DI water for SW tanks.

and the bacteria's don't live in the water column, they live on surfaces.

Right on the money here. The bacteria will live on LR, glass wall and equipment surfaces . Not in the water. You`ll need to cycle your tank.

So the water is really just a carrier to create the bacteria on various surfaces which provides the lifecycle needs of plant and animal life within the aquarium...........and the addition of salt is what makes the different bacteria grow?

I was thinking that I'd use the PWC water from established FW tanks to charge a 70g tank, then add the medium to change the environment to SW. Guess I won't go that route. It makes sense that fresh and salt water won't support the same bacteria. { I wonder if that is the reason for adding salt to fight ick.....}

I've been tempted to purchase an RO device to deal with my hard water. Perhaps I should make that investment which would serve both FW and SW aquaria.

I'm reading all I can and trying to understand this SW program. I've got a lot to learn.....

Thanks

CH

The water will have a very small amount of the beneficial bacteria. As stated above, the bacteria will grow on/in your LR, substrate, and many other surfaces like some filter media and sponges. SW and FW have their own specific types of bacteria. The ammonia source is what helps to feed the beneficial bacteria. The ammonia will produce nitrItes that are consumed by nitrAtes.

That and raise the temp (in FW) that won't work in SW. There are folks that will do a FW dip to attempt to remove parasites on SW fish. I have read this process can be harder on the fish and QT with a lower salinity with proper treatment is a better solution.
Your best bet would be a complete RO/DI unit.

Been reading here and other sites......Yes, an RO/DI unit large enough to handle both my FW and future SW tanks is where my next 'play money' will go. My practial side would say: "What play money' ......did I say wife?

I'll more than likely going tp start a SW environment in a dormant 70g tank. Love the idea of a bearbottom tank, but have to read more on this and other basic stuff first.

One of local lfs's has three SW set up's with various marine life. One of the employees said....."Oh just get your tank set up, and in a week or so , come back and try a few of these little fish.

I'll keep reading and listening.

I suggest you do not take any more advice from tht LFS. As you are learning, setting up a SW takes time, patience and money. Keep reading and researching like you are doing now. Check out our "Articles" section at the top of the page for great info on using a fishless cycle.

Hey Lando

No no I've been burned too many times....and I don't understand why these folks @ the stores [sometimes they are the owners who should know better] talk like the light's on, but nobody's home!! I'll listen, but I will check stuff out here @ AA et el, and make my own decisions based on experience and common sense.

My fishless cycle will commence with store bought shrimp in an open baggie, so I don't have to watch bits 'n pieces floating around the tank.

Anyone have experience with the bare bottom tanks?
