Have been in the aquarium hobby for some time now, but only for two years I have been using 'hightech' tanks. After these two years, I feel I am slowly moving away from the beginner phase and into intermediate territory. Also, recently I've made the decision to stop buying off the shelf fertilizers and start making my own DIY fertilizers. Started initially with nature style tanks and now reading into Dutch style tanks. Think I'll start on one within three months or so.
Looking forward to learn more on this forum and share my experiences of the past years.
Running a tank with BDBS (inert sand substrate), no root tabs, no aquasoil, and only dosing DIY ferts via EI/"non-limiting" methods has been extremely enlightening (and successful!). To help my journey, I created a tool to help myself and others who use weekly water changes and manual fert dosing:
This week, let's get into the details to help everyone out. Please be as specific as possible, as if you were writing a standard operating procedures (SOP).
How do you dose fertilizer into your aquarium??
I'll start.
Macros: I use @Burr740's 1000ml bag of macro fertilizer and mix it into a 1000ml container of distilled water. I have it in my cabinet ready to go. When I do my weekly ~50% water change, I dose 10ml of the macro formula to the tank. So I front load the fertilizer. This contemplates that my rocks provide some GH/KH.
1. In a journal on another forum someone is only dosing 2ppm N a WEEK. Note, not NO3 but N. It was a high tech tank with bright light and CO2. Lean dosing method it was called. His plants looked great. This is new to me, but seems it’s a thing. Is the assumption that given stability, plants will adjust to whatever they are given?
I believe he had some type aquasoil, so some N was coming from that. Once this gives out, will the 2ppm N/week still be enough? Is the misunderstanding here that I’m used to EI method that gives more than enough?
Can you put information about your dry salts here too? I’m out of MgSO4, partway through everything else, so trying to figure out the best way to switch over.
Thanks for asking about this. Ive been waiting to list the ferts until retail packaging is ready to roll, that should be done in a couple of weeks. I dont have individual salts, like the MgSO4 you mentioned
What I have is the popular pre-mixed packs of both micros and macros to make your own solution. You just add the entire pack to your dosing container and mix using distilled or RO water
