No, you'll waste your time. trust me. I have a 300 gal acrylic, and if I was to have to use that scratch repair kit, i'd have goten rid of it. It works. just keep moving.
I ran hard pipe all the way to the SCWD then switched to barbs and yes a couple hose clamps, I also spent a few extra $ and put in shutoffs.
I've never had a clamp fail, course, I use milk hose from a farm supply store.
I don't have and MJ's I chose a different loyalty. I like Mags. Just bought another Mag2 yesterday to run my Ca Reactor DIY.
I don't think you can melt a t enough to turn it into a jet, thats why I used the loc-line nozels.
I like your tank, but the more I think about it, a plumbed line around the top is going to be a hassel. A hassel to clean, work around, to service... What about 2 fat water jets in each side, pointed in to the center crisscrossing. Like a tidal pool that is being sloshed from different directions...with a mag 4...And the hose clamp is mot technically one the tank, the barb is screwed onto the bulkhead, and the squid to the barb.
This is the tank I'm setting up for proping.
