most kits like the api ammonia test kit from what I hear cann't tell the difference. And both will test positive.

Chesh and rsskylight04 like this.

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Hi guys today is water change day I did a 25 % water change added prime 5x times dose And tested water before

ph6.4 ammonia .50 ppm nitrite went up to 1.0ppm and nitrate 5.0ppm

This readings are now confusing I'll test my water once I get back home tomorrow :)

What goes up, must come down! During a typical cycle, you'll see the ammonia 'spike' first. As the bacteria converts the ammonia, you'll see the nitrites spike up as the ammonia levels fall. In the final step of the process the nitrAtes will spike as the nitrIte level falls - until you *finally* get a reading of o,o,?

Looks to me like you're moving in the right direction!

My understanding is that if the pH falls too low, the bacterial colonies go dormant, and so the nitrogen cycle doesn't happen. Because of this, you would see the ammonia level rise in a previously cycled tank, as the bacteria is no longer consuming it. When the pH is this low, ammonia becomes ammonium, and as BB said, the API test kit does not differentiate between the two - so both ammonia and ammonium will give a positive test result.

Ok got it so for now it's all about keeping ph stable so nitrogen cycle can continue I'll test water once I get home :)

Time for a water change to raise your ph and drop ammonia and nitrite. I'm assuming u meant nitrate is at 5??

Idk if the people on here look down on posting information from other sites but I found a link on a different site that really helped me understand the ph thing. I will private message you the link.

ya, pH is ... it's simple alone

if you are looking at other things your pH starts to change everything else in the tank (not sure about hardness), and suddenly pH isn't simple :( ... well pH is still simple, but trying to figure out everything it's playing with can be a nightmare

Hi guys today ph is at 7.6 no more than that I tested with the high range ph test Ammonia is .50 ppm nitrite .25ppm and nitrate 5.0ppm now it seems confusing what if ph rockets up Way too high
