Dosing help

Hello everyone . I need help regarding dosing schedule . As some says no need to dose and some suggest dosing according to dosing chart of Seachem. I have 36 gallon tank . Using sunsun b 302 filter , beams work da light , and pressurise co2 and running them for 6-7 hours and using Ada Amazonia with power sand m. Please advice if I should do liq dosing ( have npk, iron , flourish and flourish advance ) plus I added 10 root tabs in different places in Aqaurium . So please tell me if o should continue dosing liq ferts as pert their chart or no need . Or if I should stop so until when ?
Thank you

Could you share detailed photos of your aquarium so we can see the kind of plants you have?

The discus fish have no chance of eating properly in the presence of Pterophyllum scalare and also on the top of the granular substrate. As for the fertilizer question, you donít need to add any nitrogen or phosphate since the fish supply enough for the plants. You donít want any root tabs with ADA substrate, it doesnít need them. You only need to supply 30 ppm potassium with water changes and daily complete trace element additions. Keep checking NO3 concentration and if over 10 - 15 ppm then increase water changes. Also, knowing source water Ca, Mg and KH would help.

Hello
Thank you . As per your reply . I have stopped dosing other ferts. But please advise can I dose Seachem flourish as it contains trace elements . Or as I said before I added root tabs which I checked also have trace (few) . So please tell me if I need to buy Seachem trace or flourish will work. Thank you

Since you will need lots of K potassium you could buy dry salt K2SO4. It is very inexpensive. With Seachem Potassium you are paying for water as there is only 9.3 grams of K2SO4 in 100 ml Seachem Potassium.

Seachem Flourish Comprehensive has very little trace elements, other than Fe. Because you have CO2 you need to dose Seachem Flourish Trace as well. Flourish Trace does not have Fe so you need to dose both products. You mentioned you have Seachem Flourish Iron, you donít need it, it would make it worse because there is enough Fe in Seachem Flourish Comprehensive.

Hello
Thank you very very much for your reply . I have ordered Seachem trace and also dry potassium (https://www.amazon.in/gp/aw/d/B07QB9...5B9PLXTI&psc=1).
One last think . Please guide me with the dosing schedule . What to dose on which day and quantity with 50% water change on 7th day . Just to share I am doing 6 hours co2 and 7 hours light (36 gallon tank)
Thank you very much

What are your ammonia numbers? What is your water change schedule? I'm shocked that you put all those big fish in, especially the discus after 2 weeks using aquasoil.

Hello. I did water test yesterday and ph was 7.0, ammonia and nitrite was 0 and nitrate colour was between 20-40.
I was doing 70-80% water change twice in a week but now 70-80 once a week . It’s exact one month today . I have no success with carpet and some lower plants have brown edges . Please help me with dosing . I am so much confuse about dosing . On what to dosage and on which day and how much .
Thank you
Note : light was close when I took picture . So plant are sleeping and did trimming also day before yesterday

Aquatrition Potassium says 5 ml / 60 L adds 5 ppm K. If true then there is something else added because K2SO4 alone wouldnít dissolve in the bottle. They also say there is some pH buffering capacity and 0.25 dKH. This leads to KHCO3 or K2CO3. Both compounds push pH up which is bad for your substrate. You should have ordered dry powder K2SO4 instead.

If you use this Aquatrition Potassium with 36 gallon aquarium then add with every water change 30 ppm K:

20% 14.4 ml
30% 21.6 ml
40% 28.8 ml
50% 36.0 ml
60% 43.2 ml
70% 50.4 ml
80% 57.6 ml

The product at 2 ml / gallon adds 30 ppm K.

For the Seachem Flourish Comprehensive and Seachem Flourish Trace use manufacturer recommended dosing, see Directions / Dosage Calculator.

Thank you for your advice . I cancelled that one and reordered the powerderd one (https://www.amazon.in/RADONGROW-Pota...gateway&sr=8-1) . Thank you .
Please just to clear my self . I will dose flourish , trace according to days and dosage in chart . And then 2 ml K after very water change . One last quick question . How will I make this powder to liquid .

How are you injecting CO2? 24/7 or Solenoid? This ph seems high for CO2 injection unless you have high kh.
Plants are melting and unhappy need to understand the whole picture.

Very unlikely his KH is high with new AS.
