Hi All Am completely new to keeping fish so please be gentle with me.Bought a 64l tank and accessories from pah for a tropical set up,but rather than killing the poor fishes,after finding your website decided to try the fishless tank cycle.After 4 weeks the ammonia readings are still between 3 and 4ppm and there is still no nitrite reading.Any advice as to the next step would be greatly appreciated.
I noticed you're in Caithness, so I have to ask, does your water conditioner remove chloramine as well as chlorine? Given your location, I'd think that was the problem - chloramine preventing bacteria from colonising your filter.
Hi Again Thanks for your quick replies.First the filter that came in the kit is an Interpet internal power filter.The ammonia came from a local chemical supplier,couldn`t get ammonia anywhere else.He said it was 9% ammonia.The ammonia readings where above 6 to start with so i ended up doing a 50% water change to bring it down.Is it possible it has damaged the foam filters and they may need replacing.Secondly it is Interpet Bioactive Tapsafe water treatment and it says on the bottle it removes toxic Chloramine.
Hi There I am using API test strips,am waiting on a master test kit to come home after a member on here recommended it.i haven`t added any more ammonia as the readings were over 3ppm.There is a carbon filter inside the filter.
Remove the carbon. It's only needed when you're removing medications or other impurities from the water. If kept in the filter permanently, it needs replacing every few weeks, which is as expensive as it is unnecessary.
Be aware that the test strips are notoriously inaccurate. Might be worth adding some ammonia to the tank to keep it ticking over until the master kit arrives.
Might be worth testing the tank pH too. pH can swing around a bit when cycling and if it drops to 6 or below, it can halt the cycling. This happened twice to me. If this is the case you can raise pH by adding a little bicarbonate of soda, not to be confused with baking soda. Start with half a level teaspoon and keep testing. Easier to add a little more if needed than to remove once it's in.
