Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I guess u never herd about premium aquatics lol. Brs is more rip off then others and shipping stupidly slow unles u pay extra. Premium u order and 2 days is in your house. look around more
u don’t have to do tubing there better is ultra flex pvc and add check valve there on vertical from your return that will prevent lots of water draining back to sump when u turn of pump. Get true union check valve easier to remove it if u need to clean it
The working time deference is between 4 and 3, 4 gives you little more time then 3. 16 is more like glue And doesn’t melt acrylic while bonding which gives you weaker seam.
Don’t use Weldon 16 to bond acrylic if u want to build anything to hold water.. weldon 4 or weldon 3 alternatively u can use chemicals to make solvent but this is more complicated
