OK i have heard both sides of the story as far as fish and fishless cycle. That aside, if I wanted to cycle WITH fish should I go ahead and stock the tank pretty good at first to get the cycle started?? I hear that if you just add a few fish and cycle, then when u add more you could get a mini-cycle and I am trying to figure out the point to that!!!!!!!!!! I am not saying completely stock but add most of what i want. it is a 75 gallon if that needs to be known!!!!!!!!!!!!

WOW quick response.

I am thinking about 1-2 Severums as the mian attraction. As faar as the others, i am open. ANy suggesitons?? I have 4 giant danios i am putting in also. Was toild that isnt enuf to cycle with if using fish. They are about 1 1/2 inches big now. Might add Kribs, still thinking about it really, maybe Corys Red tail Shark.

Being that you have a 75 g tanks, if you start out stocking very slowly, theres a good chance you can have a virtually silent cycle depending on the size of the fish you are adding.

if I wanted to cycle WITH fish should I go ahead and stock the tank pretty good at first to get the cycle started

My recomendation is to start out slowly, there again, I have no clue what fish you are going to stock, so I can't recomend how many of what to put in to start with. Adding a large amount of fish at one time will ultimately be a disaster. It only takes one fish to produce ammonia and get the cycle started. Bacteria will not grow any faster with lots of ammonia or nitrites than it will with just a little. What you want to do is add a small bioload, as your ammonia and nitrites get to zero, add another fish. You will have a short spike in your parameters (mini cycle), but it won't be near as long as it took the initial cycle to complete. For healthy, happy fish during a fishy cycle..stock slowly.

I hear that if you just add a few fish and cycle, then when u add more you could get a mini-cycle and I am trying to figure out the point to that
If you add new fish to a fully cycled tank, regardless of how long the tank has been set up, you are going to experience a mini cycle. Depending on how many and what size fish you add to a cycled tank will determine how long the mini cycle lasts and what extreme you water parameters will go and how fast the parameters will rise (ammonia, nitrite, nitrate). Most often this mini cycle is so fast, we do not notice it.

Buy, if you havent done so already, a liquid test kit for testing your water. I recomend the aquarium pharmaceuticals master test kit. Its really simple to use and not at all expensive.

BLUE and HD# Tell me this then!!!!!!!!!

I have spotted a Severum at the LFS, small about 1 1/2 omches. I know impulse buy and all, but I am home now lol. The colors and makrings are incredible and I was wondering if this fish could withstand a cycle with 4 danios. I will be running 2 Aquaclear 70 filters on this tank if that matters.Again it is 75 gallon tank and I do already have a Master kit Blue!!!!!!!!!!!! Thanks for the advice though!!!!!!!!!!!!!

I say yes in a 75 g tank. Just teset your water parameters and change water as necessary (ammonia, nitrite < .25) You want to keep your ammonia and nitrite below .25.

You guys are GREAT!!!!!!!!!!!

Blue--------- or anyone--- If those things rise above .25 what do I do?? I have heard not to add anything and let the cycle take its course. I have then heard to add something to settle the ammonia down to not stress the fish so much!!!!!!! But i would think that would hamper the cycle itself as as I understand it the ammonia turns to nitrite, then to nitrate etc.

If the ammonia or nitrIte go over .25 ppm, do a water change. It won't hurt the cycle. Why not add bio-spira or fritz turbo start and add most of your stock?

True, but it's always best if you let the water sit and not do any water changes during a cycle. You never know what you're introducing into the water during a water change... If chlorine or something gets into the tank it will kill your tiny bacteria colony, and you're starting all over. Just one less thing that could possibly go wrong.

But if you have fish you have no choice...that's why fishless cycle is best
