New tank fishless cycling for about 3 and half weeks an a little stuck?

**livvyy** · 02-07-2013, 01:52 AM

Hi (information for tank below) I am currently fishless cycling (used the frozen prawn but have taken out as i have run out) I just brought a nitrate test today. In last 3 weeks I have had my ammonia level up in the first 2 weeks was 8.0 so i did a massive 90% water change because nothing was happening; now it is sitting at 4.0 and not sure but I don't junk I was dou f my nitrite test properly but today have defently tested for 0.25 nirIte. I tested for nitrATe and it is 5.0. My ph is currently 7.6 (coukd be higher have bot been able toget a higher oh kit as of yet). My question is should my ammonia be coming down? And is my cycle coming to an end? Any help would be much appreciated

Well it seems like you are doing a right job there and all answers to your questions "Yes". However, 4.0 for ammonia after almost 1 month period might mean that you still have some traces of organic mineralization process which brings up ammonia. Maybe prawn was "too greazy", i don't know. Or your live plants are not doing well and some leaves died. Sometimes their roots in fresh tanks start to decompose in a gravel, you may examine accurately. Keep cheking water params.

Thanks thats so much help i thought there was somehing wronf with it and started to freak until i brought the nitrAte tester and more relieved...Would the snails that's been in there be causing the ammonia to stay around 4.0 I've been picking them out as I see them... There must have been snail eggs somewhere even though I isolated the plants for two days and rinsed them I dunno but could they cause the ammonia problem?

Ammonia of 4 ppm is rather high and will slow the bacteria growth for the nitrite cycle. Having snails in such high ammonia is hard on them and I'm not clear on why you have animals in the tank at all since you are cycling using added ammonia (fishless.)

The snails are not causing ammonia levels that high & I am clear on it. They hitchhiked in on the plants.

Since you have TrItes showing I would cut your ammonia dosage in half [Meaning only bring it to 2ppm] and carry on. IMO 4ppm is overdosing to cycle [what I assume is] a 50 Liter tank [If it's 50G then you it was fine but dropping of the dose still applies.]

EDIT: Wait.. Are you saying your ammonia doesn't drop from 4ppm on it's own at all?
