So I cycled this tank recently and did a 50% water change followed by a 70% water change then left it a week and checked the levels again ammonia 0 nitrite 0 nitrate 100after both 50% and 70% so did a 80% last night checked the nitrate this morning still sky high for back story fluval flex 34L recently cycled

Just so you know I’ve used two different test kits if this fails is a 100% water my only option I have no live stock

Test your RODI water for nitrates.

Test your RODI water for nitrates.

That was my first thought there all clear tho

Got a hanna checker?
Test your nitrates before water change, then do a 30-35% water change, then test again, nitrates should be down by 1/3rd instantly.

Nitrites have gone back up to .5 what’s going on

 

[connormoon]

After running the test again nitrates still at 100 and nitrite at .25

Nitrites interfere with your nitrate measurements. Don’t test nitrate till your nitrites are 0.

They were sitting at 0 for a week or two I don’t know what’s shot it up again
