ATPN+

[thewelshwonder]

Could you please tell me how much TPN+ i should add daily,my tank is a rio 240,the only other fert i'm using is jbl ferropol 24, the tank also has a pressurised co2 system with 22.5 mg/l of co2,thanks in advance Dean

 

[George Farmer]

I would start with 5ml per day and work up if necessary.

 

[thewelshwonder]

thanks for the quick reply,will apn+ help with yellowing leaves?

this is the tank at present


and this is the problem i'm having with my plants

I used to dose 5ml per day on my Rio 125 so that might be on the low side, but start with 5 like George sugested and work it up if you see deficiencies, you do have a big plant mass so you might need more than 5ml.

 

[vauxhallmark]

I use 3ml per day on 60l - maybe I could reduce that - have never tried!

would you continue with the feropol 24 aswell? this is the manufacturers claim
•The daily feed for luxuriant aquarium plants.
•Optimum, targeted care, provides all vital trace elements which cannot be provided by long-term fertilizers.
•Promotes lush growth, even in delicate aquarium plants.
•Prevents deficiencies.
•Contains no phosphates or nitrates.

Where have you got the 22.5mg/l of CO2 from? It seems like you have used a pH/ KH table which are innacurate. Take a look here for more information: viewtopic.php?f=34&t=467

I dosed 3ml on my 60l too, Mark

Nitrogen defficiency is a sign of yellow leaves. Plants get there Nitrogen from Nitrate so that could explain why.

TPN+ contains everything apart from co2 that your plants require.
You shouldn't need to dose anything else, but you can if you feel your tank requires a different dosing regime than through TPN+ alone.

this is the colour in my drop checker


is this about right?

 

[Superman]

Are you using 4dkh water in the drop checker? Otherwise the readings could/will be misleading.

 

[gratts]

Slightly darker than optimum. Try increasing the bubble rate a little.

im using tank water as per the instructions on the drop checker,also i cant drop the ph below 7.0 as i keep nerite snails and they need a ph above 7.0,reading the link it says 30ppm will drop the ph to 6.6,i'll get some 4dkh solution and see what the difference is.

that is a problem them, even Nitrates & phosphates in the water can change the reading!

Hi,
You'd be well advised to stop reading those instruction because they will only cause you grief. Read this instead=> CO2 MEASUREMENT USING A DROP CHECKER

Cheers,

 

[thewelshwonder]

can you tell me the best time of day to add the apn+ please

 

[ceg4048]

Hi,
Any nutrient product can be added to the tank at whatever time of the day you please.

Cheers,
