so just cycled my tank and . . .

[Dave1993]

Hanna saying i have 286 nitrates

api saying i have 0

all i have done is add like 3.5ppm ammonia could this have caused 286 nitrates i think not?

and i did a 75% water change so god knows what hanna would have said before the 75% water change maybe 500 nitrates?

what 1 would you trust as i have coral coming soon so kind of need to know

 

[Troylee]

Most likely still have nitrite in the system and it’s giving you a false nitrate reading.. not sure I would put any corals in a tank that’s newly cycled ..

Also if you’re trying to cycle your tank the worst thing you can do is a water change.. let the tank be and do it’s thing and it will all balance out..
API is junk! Trust the Hannah

its cycled added rock from my 3 year old 90

The Hanna Nitrate HR checker measures up to 75 ppm, the LR checker 5 ppm.

Which one are you using?

 

[lapin]

Since you will not be adding fish, you will be fine. Just add a bottle of bacteria if you are worried.

What is your ammonia level?

Cycled rock = ready for coral

 

[N1tew0lf1212]

What nitrate hanna checker do you have?

 

[I never finish anythi]

Hope it's not expensive coral

What is your ammonia level?

ammonia is 0 the tank is cycled i have have 286 nitrates with hanna

0 nitrates with api

 

[TokenReefer]

When did you add the ammonia?

 

[Troylee]

Well to answer your question.. api is junk! Trust the Hannah.. how big is the tank and how old? How did you cycle it? Any live stock currently

 

[Dave1993]

What nitrate hanna checker do you have?

high range i diluted 1ml tank water 9ml rodi and it came back 28ppm

the tank got dr tims ammonia chloride in about 3.5ppm it was stuck at 1.5ppm till i added rock from my 90 and now the nitrates are 286 and this is after a 75% water change surely 3.5ppm ammonia can't cause like 500 nitrates (which is what it would have been before a water change) its a fluval evo 13.5

 

[Dave1993]

i have 1 snail i put in when ammonia was reading 0 to test if it lived and it did

 

[Dave1993]

i just think its impossible that i "had" 500 nitrates

 

[Dave1993]

i didnt do a water change on my 90 for 6 months and that only had 200 nitrates

 

[Troylee]

Have you tried a new regent for the checker? Maybe they’re bad.. I use sailfert for nitrates and they’re still high in my tank..

i have just ordered new regents like 1 week ago used them exp date 2027 or 2026 1 of them

 

[Dave1993]

like too have 500 nitrates what would i need in my tank a 4 month old rotten blue whale carcass?

Could be a lot of die off maybe from the live rock going into a sterile water? Idk seems a little weird… I have around 100 right now and my corals are fine and loving it! I can’t get them down with chaeto or carbon dosing… water changes don’t budge them either.. my system was purchased second hand and is 10 years old but was a fowlr so it was heavily fed and never really maintained for corals.. I think the rocks bound it up pretty good since the sand bed is only 1/2” deep at best.
