Thanks Cheryl. I was close to trying a co2 reactor but after seeing the article at this link
http://www.qsl.net/w2wdx/aquaria/diyco2.html I wanted to redesign it. One item is the check valve. There are some great points in this article. Only item I'm debating on is the diffusing method. First thing I need to do is get more juice or gatorade bottles and drink them.
I think the lights might be a better thing to upgrade first though so I'm still a long way off. I've looked at AH supply and am still working out some details. Switching to one of their kits (with a diy hood) would pretty much remove my entire hood from my tank and I'm not sure that would work yet. I need to do more research. I have several posts on the subject right now.
In the meantime I have some experiments going with the buckets and some bowls. Only challenge is trying to keep the house from looking like a warehouse. It's times like this that I miss not have a basement.
