Papagoomba Posted September 24, 2021 Share Posted September 24, 2021 I feel like i ask questions about this alot but want to make sure im doing things correctly. Doing a fishless cycle with a lightly planted tank. A couple val, some dwarf hairgrass which doesnt seem like its doing well and a bit of java moss. My question is my ammonia levels drop from 4 ppm to 0 in 24 hours if not less. My nitrite levels stay around 2-5 ppm but my worry is my nitrate levels are at around 80 currently and have been for 2 days. Should i do a water change or just leave it for my plants to deal with? Will this affect my cycle? 1 Link to comment Share on other sites More sharing options...
GameCzar Posted September 24, 2021 Share Posted September 24, 2021 You really need those nitrites to be zero, and your nitrates to be near 20-40 or less. How long has it been cycling? It looks to me like your bacteria have consumed the ammonia and are currently converting it to nitrites, then to nitrates. Sometimes this takes a bit to complete, but once you get it down to just high nitrates you can deal with it through water changes. Cycling is confusing, ask questions! 2 Link to comment Share on other sites More sharing options...
Papagoomba Posted September 24, 2021 Author Share Posted September 24, 2021 its been cycling for a month as of today. my nitrites im still waiting to drop then ill know the cycle is done. I get that part. the part im not sure on is if i need to do a water change to combat the nitrates in the water which im assuming are from the nitrites being broken down a bit and from maybe the root tabs that are in the tank for the val and hairgrass. im not sure if the nitrates being so high will affect the cycle or if its another case of just be patient and wait and those will go away on there own from the plants Link to comment Share on other sites More sharing options...
Patrick_G Posted September 24, 2021 Share Posted September 24, 2021 I’d do what @GameCzar suggested but also test your tap water to see if some of the Nitrates are coming from there. So wait until the Nitrite is zero, then change water until Nitrate is 20ish and test your tap water. 1 Link to comment Share on other sites More sharing options...

Papagoomba Posted September 25, 2021 Author Share Posted September 25, 2021 I love the timing on this. I just did my water test for the day and it appears my tank has now cycled. Nitrite levels are at 0. ammonia was still at around .25 ppm tho. so going to do another dose today and then test again tomarrow to see where i am at. I am now very excited to finally start stocking 1 Link to comment Share on other sites More sharing options...
