Planning on getting back into the hobby

[Fish Think Pink]

I used to have a 180 gal. tank about 22 years ago. I currently do not have any set up at all. I plan on setting up a new system in the next few months. First of all I need to re-educate myself because I forgot nearly everything. I will probably be looking at 150 to 180 gallon tank again. I am located in central Canada. I plan on doing a lot of reading before I make the commitment.

Welcome! Glad you joined. Planners always seem to do the best in this hobby - Good for you!!

Have you considered starting your build thread? I found its a great place to document my tank's evolution for myself. I started tank first then joined, so I'm still finding myself going back collecting pictures & updating historically as well as current state. Once you create your first post in your thread and link it to your account, they will give you build badge (look left, under my ID). I wish I had started while I was still researching and planning. It sounds like you have a strong plan to be in this phase for a while, so now would be a great time to capture those plans for yourself

This might help you find people local to you in Canada:

This is a good reference book type online article I still review:
