Hi Guys

Its been a long time since i do my fish tank a favor!

Realised that i have the following fertilizer compounds that i hope to concoct for my 155L tank. Below are my compounds in 100g bottles.

1) NaHCO3
2) KH2PO4
3) MgSO4.7H2O
4) NaS2O3.5H2)
5) 13% Fe

Cant quite figure how to mix them since my last concoction was ages. Moreover forgotton which website that break down the individual element.

Thanks

Stephen
