2 part question for ya.
1. I have a 50 Gal long with DIY Co2. I have the nutrafin C02 system, I put the output spray into a powerhead. My question is how much DIY Co2 do you need for a 50 Gal? Would I gain anything by adding a second (or third) container of Co2 to the system. Not only to regulate the flow but to bump up the output?
2. About Ferts, I plan on starting up an EI regime next week. I bought a bunch of ferts from my local hydroponics store. My question is concerning the Chelated Trace Element I recieved. THe guy said it has copper in it. I know that Copper is a no-no. So What can I use instead? CSM+B is a fish store speciality? I asked the guy for some in the hydro store and he was like wah??? I have flourish Searchem, Can I use this instead? I understand that it has trace elements aswell but I figured CSM+B is the 'crem de la crem' of trace.
Thanks for your time, Appreciate any responses.
