Need some AS advice.
Alright so I just got a bunch of Aquasoil for my new 40 gallon breeder. I went through a huge brown slime algae, Rhizo, outbreak. Biggest the World has ever seen and that was with constant water changes. I figure that is because my soil volume in comparison to water volume is really high. About 45 liters so a little over a 1/4 of my tank volume. But with the high rock volume it is actually even higher when compared against water. I can only get 26 gallons of water into the 40 breeder. I would assume my AS will last for a very long time, from what I have heard, but I am skeptical. I have a bunch of lava rubble and bigger lava rocks at the base for support and water circulation. I hope I don't get hydrogen sulfide. I doubt I will.
Now the algae is gone and most everything is looking better. My S. repens is not doing well. My blyxa J is doing really well and I just got some UG and Fissidens, so we will wait and see...
My concern is how much liquid dosing should I do? People give mixed opinions. Some people do minimal to no dosing and claim the soil lasts for 1 year, I have even heard 2-3 years! As in slowly releasing nutrients until they are gone? I don't really do a lot of liquid dosing and rely heavily on DIY osmocote+ or Dynamite plant food root tabs in eco-complete. Do I need to add root tabs to AS? I am trying to get out of my comfort zone and wanted to try AS out, but it is ruining my system/method. I think that slow release poly coated DIY root tabs with chelated micro liquid dosing here and there grows plants better and faster than anything I have ever tried, IME. I want to continue with light liquid dosing. As well as small water changes, I only do bi-weekly 20% changes. Don't mention anything about EI method. Been there done that. Not my style and inefficient to say the least. No offense Thomas. And I want to continue to rely on the substrate for nutrients. Does AS have sufficient nutrients to sustain, continued rapid growth of plants, for a long period of time?
Any advice on sustained growth and dosing would be appreciated.
I haven't been dosing anything but Excel here and there. Really high lighting, Finnex Ray 2- 2 fixtures and pressurized Co2.
