I have a 2005 Coleman I can't find the model # but the book has 300 & 400 Series. It's a 6 seat spa w/neck waterfall on each side,need to know how many gallons, plus the waterfall top valve is broken & all I can find is the little ones.

Need a Coleman Spas 630 Series Topside Control - 103-305 / -103-306

Yes I have a 2005 made Coleman... The630 series has 4 extra controls on. Right... 630 series has 3. Manual says filled weight at near #4000. Previous ( forgot about those busted bits online search Coleman spa by maax.they should be there for purchaced however not easy to do)((I stand corrected if not freeze damaged the owner book has the method for replacing or just cleaning the jets and can be done top side)) owner suggested 380 gallon. I think closer to 450 - 480 all the chem kits operate based on ppm. Gallons won't make much difference. If using add-in chlorine set to minimum setting and test water if u have issues. Chlorine will corrode the metal of the heater and if used the valves and impeller on the pumps.

Max spa or
