this is very interesting, i guess its all becomes personal choice, but i do like the principal of it solid carbon dosing... i have done zeovit and had a success... maybe in my new built i have biopallets.. may i ask you a bit more question if i may! how would you spot the good and bad in biopallets as there are so many brands? do you use any GFO do remove the phosphates? or eco back does the job? what are your views on the all in one bio pallets which recently got released?
Also look forward to see some more pictures of your tank,
Thanks
