Newbie to fishless cycling, help?

Postby AlicesAquarium » Thu Aug 10, 2017 10:19 am

So I think I have understood the basic principals of the fishless cycle routine. The problem I have is that over the next 2 months I'm away from home (and the tank) for a few days. I go away on August 18th until the 21st so I am going to start cycling when I get back. That's all fine and nothing should go amiss (fingers crossed) however, I go away again for 5 days exactly as I would be hitting the 4 week mark of cycling. If I leave the tank will I be ruining the cycle and cancelling out all the work I will have put in up until that point?

Would it be easier to just dose with a biological additive and keep testing the water accordingly? What other methods are there I could use that might be easier for my situation? I'm not in too much of a rush but I don't want to wait months or lose all progress I make over a few days away.

5 days won't hurt much and sometimes it even helps.

add ammonia as soon as possible nothing will happen for a few days anyway. so you will be ok leaving for a day or two early on.

ammonia only needs to be added when its level drops.

do not be in a rush only bad things happen fast in fishkeeping.

Hi daz4321, thanks for your reply. So the ammonia dosing only happens when it drops? Could you explain the process to me - I think I've misunderstood as I thought it was daily dosing until the nitrite started to make an appearance?

Also when do you begin with the water changes? Is adding fish food required as well?

Many thanks

https://fishlady.co.uk/fishless-cycling ... h-ammonia/

read that carefully it is one of the best guides

water changes only if you get extremely high nitrates while cycling (100ppm +), once cycled my preference is 2x90% water changes to remove any waste products left from the cycling.

no fish food required (ammonia is the food source that the bacteria use (rotted food produces ammonia)

Thanks again for the link, its really useful. My main question still stands though and doesn't appear clearly to me from the article - the initial 10 (ish) days of the cycling, should I be dosing the calculated amount daily? Or dose once and in 10 days it should start to decline?

dose ammonia to required level then wait testing every few days initially, when ammonia levels drop below 1ppm redose to the starting level then wait for the drop again, repeat (testing more often) until ammonia and nitrite fall to zero at least 24hrs after dosing(some recommend 12hrs)

Thank you! Started my cycle this evening so look forward to seeing progress in a few weeks :)
