it wont drop the PH to that extent

 

[sjolliff]

How much does it drop?

Are the plants releasing CO2 during the day?

plants are releasing CO2 all the time, but not enough to lower the PH by 1
any wood in the tank?

 

[sjolliff]

yeah. 2 pieces been there forever, but added a new one a couple of weeks ago

 

[Truck]

the new one may have dropped the PH

did it leach tannins

 

[sjolliff]

It came from AE they said its soaked for weeks before selling
i boiled it for about 2hrs then washed before adding
cant see any in the tank

 

[sjolliff]

I think it is the new wood as i did a 50%WC last night and did not dose this morn and the ph went from 6.4 to 5-6

i cant take the wood out as the discus have just spawned on it

Do they cause a funny reading for ammonia?
i recently had an ammonia spike
0 in the morn but when i tested 4-6 hours later after dosing it read nearly 0.25
but today it was 0 in the morn i did not dose and the reading was still 0 4-6 hours later

TPN+ does contain ammonia, but not enough to cause any problems

 

[sjolliff]

Cheers, iv only had this problem since upping the dosage from 5ml to 15ml daily

my tank holds 400L of water, but with sand and rocks etc probably around 330L-350L could i be overdosing

i still want to use as the plants are doing great and its kepping the algae away

im dosing 5ml a day on a 125 litre, so you have no problem there!

 

[sjolliff]

Would i see a change if i dose 10ml?

from the 15ml i have been adding how much ammonia would i be putting my tank?

is it just a trace which would not be picked up via api liquid tests?

 

[aaronnorth]

TPN+ uses ammonium nitrate (NH4NO3),

so 15ml will add approx, 0.4ppm NH4

changing it to 10ml will add approx, 0.25ppm NH4


I wouldnt be worrying about it, as everyone who use Tropica doses the same quantities without problems, as an experiment, I once dose 10ml on my 60l for 1 week and the growth rate was amazing, no adverse affects to shrimp or fish. I only tried it because someone did it by accident and witnessed amazing results so i had to try it for myself

 

[sjolliff]

Well i added 15ml of TPN+ and hour later i tested and it was between 0.25 and 0.50ppm of ammonia
its been a 0 for over 24hrs
