Hi pest control
Just bear in mind the figures quoted above are for your tank (216l), therefore for a 120l you would reduce the amount of powders in the mix by approximately half. No need to be mega precise. If your brother is not running CO2 then a dose half the strength of yours should be more than enough.
Altenatively, mix up the batch for yourself and let your brother use the same solution, just make sure he doses half the amount you do. Saves making up two different strength batches.
Of course he can 😀. That's the beauty of this system.pest control said:EDIT: i've just thought. could my brother use the same dosage as me? his tank is 120l (juwel lido 120) with 1.5 wpg of t5, and no co2. he is dosing the same TPN+ as me ATM, so could he dose the same EI?
