CO2 purchasing help
I have been into aquariums for a long time, so normal stuff is by no means new to me. Nor are aquarium plants, or so I thought. I have begun researching CO2 and am just completely overwhelmed by the information, conflicting reviews out there. I will be setting up CO2 on a 75 gallon tank and have no clue where to turn to get what I need. I am currently trying to find a local store to purchase and/or fill my CO2 tank. I would prefer to do most of my purchasing on Amazon however, as I will be using an Amazon credit card and just paying it back when my taxes come back. I have gotten several recommendation to go with greanleaf products, and several recommendations NOT to go with their products. I can pretty much say that about any brand out there right now. As they do not sell on Amazon it looks as if I am leaning toward NOT. Here is where I need help. I am linking a couple items I am considering purchasing and need to know what you all think. I have found threads about some of these but a lot of the reviews are older ones.
This is the solenoid I am considering going with.
and this tank
What else am I going to need besides these two? If anyone has any recommendations of alternate products as well, please let me know. I really have no clue what I am doing despite over a month of reading. I learn mainly by doing.
I have been told I also need at least a diffuser and check valve as well. If anyone can point me to the right products, and as I said, on Amazon if possible, please help.
