Welcome to the forum!
There are several forums out there, but I strongly believe biabrewer.info (the one founded by the BIAB pioneers) is the one with the best information, less BS posted and overall much more reliable and trustworthy information.
Have you upgraded your equipment, as of yet...? I had a 5-gallon stainless pot for brewing extract. Would brew with up to 3gallons and then top off fermenter with water. Not near large enough for BIAB whole grain batches. My goal was to have 5-gallon batches of average (5-6% ABV) at the start, and wanted to occasionally brew larger gravity beers too.A 10-gallon pot will just do it...but you will really appreciate (later) a larger pot! I ended up with a 16 gallon stainless steel pot and am so glad that I bought that size! Could actually justify some larger, but this size is very workable. Most often I brew 8-9 gallon batches. Put 5 gallons in my Corney keg, bottle several bottles for gifts and/or competition and put a couple gallons in cleaned and sanitized PTFE milk jugs. So when I have a keg that runs through too quick I can put some “reserve” beer in, carbonate it and be back in business... You may still bottle and not plan to need more than 5 gallons of finished beer...but this gives you the flexibility, and doesn’t cost much extra!
There are a lot of excellent posts and information on the site. I will post some links for some of it. Others, you just have to look, and will be rewarded with many nuggets of great advice!
- An Excel file that Pat and others put many thousand hours into developing. Hugely helpful to use with your brew day. Great for planning recipes or copying recipes. Pat just updated the file. I’ve used the previous one for the past few years and it has worked great! viewtopic.php?f=55&t=4059
