Re: [Killietalk] Tank cycling



Hi Melvin,

The best way to do fishless cycling is to buy a sponge filter set it up in a healthy existing fish stir up a little of the gravel let it run for a couple of days.   Bingo instant cycled.   

when I know I am going to set up several new tanks at a time ie: fish coming home from a show.  
I will actually place 4-5 spnge filters around in existing healthy tanks and let them run prior to the show.  

If i should happen to buy more fish than I had planned I swap out some spawning mops with other species.  Usually targeting completely  unrelated species.  ie: Ep. lamottei and Riv. cryptocallus  eggs are nothing alike and neither are the fish.   The mop has a substantial Bio filter already there.   

A good clump of Java moss, water sprite(with good roots), and any number of other plant species will also do the trick.  Having a high surface area!!    DO NOT rinse simply shake them a little and transfer. 

When I worked in a pet shop for 6 years I came up with several alternatives (before bacterial additives like cycle and bio stars).  I used to recommend 50% water changes 3x's weekly for 2-3 weeks then twice weekly for 2 weeks then 25% weekly or biweekly from then on.   What happened was that there was little chance for a major shift in ammonia, nirtite, or nitrates!!   The Customer could moderately stock most aquariums without difficulty or losses.   A much more even load of ammonia allowing time for the necessary bacteria to grow.

The second alternative was simply giving them a cup of wet, not saturated gravel from a healthy tank. This would hold a sound bio load and cycle the tank without fail.   usually from the expensive odd ball tanks ie: electric cats which would stay in the stores for months on end.    Besides It would give the customers a laugh when I got nailed!!  POINT of that was that the oddballs were obviously healthy and the tanks were not exposed to a constant flow of unhealthy fish!!
