Well you can't silicone acrylic but I don't think the leak is at the acrylic. I could potentially silicone between the bulkhead and pvc I suppose. I changed it the bulkhead yesterday. Will repeat a leak test this afternoon.

It actually doesn't matter if you've got acrylic or glass, the bulkhead will have threads on the outside so the nut can secure it to the tank itself. The slip portion is for the pipe and that is on the inside of the bulkhead that protrudes through the tank. It's generally not recommended to silicone the bulkhead in place as it's a REAL pain to remove or adjust.Noob question since I’ve never had acrylic - can you silicon and seal the bulkhead from the exterior side of the tank? It might be easier to remove silicon from just one side than to cut the piping if you glue a slip in.
Ahhh gotcha, so that should eliminate a bad seal that is leaking down into the threads. Are you using schedule 80 bulkheads (grey) and schedule 40 PVC fitting (white)? I haven't ever had issues with the threads not being compatible but it might be worth trying a schedule 80 threaded adapter to the PVC pipe? (If it still leaks after your next test).Yes, the hole was large enough to fit my hand into and clean the bottom. I have it emptied again so I can't take a picture of it leaking however I could watch the drop form in the small space where the bulkhead thread ends and the pvc adapter comes out of. There area above it is dry. I ran my hand along the outside of the bulkhead and external threads which are palpably dry as well.
Just found this thread and read through all of it. It would be awesome to buy a house with a built in tank. I have found my 3d printers to be super handy. If there no part that does exactly what I need it to do, design it and print it. Hopefully you get the bulkhead issue figured out.
I almost went bamboo labs but couldn't imagine I would need to print multiple colors. I wanted a core xy so I went qidi x-max 3, a little cheaper but no option for multiple colors. I still have my ender3s, it's old reliable.My 3d printer may be the most important piece of gear I have bought for the aquarium (upgraded from and ender3 to a Bambu labs P1S). I have designed and printed out all sorts of things since starting this build.
So glad to hear you were able to cross this hurdle with the leaking!No leaks through the weekend! I think we're good. I was able to work on other things for once this weekend.
Started up the protein skimmer and working on getting it broken in. I have the ATO hooked up but haven't actually started it up since the skimmer is going a little crazy right now. Will get it going one the skimmer settles in.

I did not wash my sand prior to putting it in the tank. Carrying those large bags up and over and into the tank was heavy enough dry much less soaking wet. I've started stirring up the sand and trying to clean up the dust through filtering and skimming. I think that's going to take some time to clear a lot of it out but will be worth it to do now.
The next step to work on is cutting some acrylic for lids to the sumps and to my quarantine tanks.
I think venting the room would help for sure. Where are you measuring temp at? The sump or the display?Continuing to filter out the silt from my sand polishing up the water. In addition this week I created some nice acrylic lids for the sections of my sump and for my QT tanks.

Alas the law of unintended consequences struck. My water temp had been running at roughly 78 degrees, the temp I was aiming for, and it was maintaining it without the heaters. When I put on the lids, the temp has slowly increased up to 79.5. This is without any high-powered lights installed over the tank yet.
Well, there is that gigantic chiller the previous tank owner installed that I never used in my freshwater build...

So I fired that bad boy up and boy did it work and quickly too. And boy did that room heat up even faster! This thing isn't vented anywhere so it got unbearably hot in there real fast, so I cut it off. I bet the previous owner never used that chiller because of how hot the room would get.
I guess my nice lids may not get much use after all. For now I've removed the lid from the top sump and one of the three sections from the bottom sump to see what the temps will do over time this weekend. I will have to switch gears and look at perhaps a fan to blow onto the upper sump. Perhaps adding some vents and fans to blow warm air out of the fish room and into the main hall to drop the temp in the fish room a little more since it runs a little hotter in there.
Open to suggestions on this because I'm sure the water temp will get even warmer once I add appropriate reef lights into the mix. While I was hoping to aim for a temp of 78, 80 wouldn't be terrible but I would get nervous going above that and would like to have some measures in place to address it.
I just wonder if your actual tank temp is that bad. Might be worth looking at the tank temp too just to see if that much heat is being transferred into the tank or if it's just the small volume of the sump.
