If my plans currently are to have a "generic" planted tank, is there a reason to not buy off the shelf? I'm fine with mixing my own down the road but not quite ready for that even with it being simple as stated.
I'm sorry your other thread went to the crapper!
I figured maybe I could help and hopefully make this easier.
Choosing the RODI option changes the game a little for off the shelf.
This can still be easy.
Equilibrium is $12 for 600g & NilocG GH Booster is $6 for 454g
To remineralize 200G to 6dGH w/NilocG will require 260g excluding sump.
Future 50G WC's would require 65g.
Using Equilibrium is about the same weight but higher cost.
KH could use K2CO3 or KHCO3, pick your poison, about $12.50 on the Bay.
Using K2CO3 for 1dKH in 200G is 18.6g & a 50G WC would need 4.6g
Using KHCO3 for 1dKH in 200G would be 27g @ higher cost.
You will need fertilizer too.
NilocG has a DIY EI Liquid Fert $22 with two dosing bottles.
Pre-measured packets for the 500ml bottles.
1500ml for both macro & micro.
The dosing is labeled as 5ml per 20 gallons 3x per week.
This will be a low tech tank correct, the savings gets bigger.
50ml dose once per week, 1500ml lasts 30 weeks @ 7.5ppm NO3
25ml dose once per week, 1500ml lasts 60 weeks @ .25ppm Fe
You will need to weigh the remineralizing compounds.
Zorfox's Planted Tank Calculator was used for these examples.
Deep pockets to do this with Seachem products.
Hope this post makes things seem easier.
