Surprise, Another SPS Tank (1 Viewer)

Ahh ok that makes a bit more sense :cool: I knew certain woods were stronger than others but that's as far as my woodworking knowledge goes!
 
This will be so much nicer than 2x4. I’ll just have to be careful with screw placement going into the ends but otherwise should be a breeze!

Ugh so I’m running into issues achieving proper joinery with double stacked plywood. Doing pocket holes won’t work right unless I treat it like 2 separate joints as the screw wants to split the lamination. Same issue with screwing into end grain to make the box joints. I found this design online but it does not appear to use pocket holes.

As you've found out, plywood doesn't respond well to being joined parallel to the plies. If you must use screws or fasteners in that way, it is best to drill pilot holes to depth for each screw. The thickness of the screw shaft will just force the plies apart.
There is an old thread in this forum somewhere where I discuss stand building. The most important factor is glue. The glue is what will bond the joints and hold your stand together. The screws and nails are just clamps. If you use an all-weather wood glue, you could just use 18g nails to tack the stand together as the glue dries. Keep the stand plumb and square while it dries so you'll have less issues down the road.
Also remember that if you're skinning the plywood stand, attaching/gluing the panels onto the frame will contribute to the overall strength as well.

My stand is built with ¾" solid red oak and some ½" plywood and it's still holding up after eleven years of service.

Thanks Jason.

I’ve typically overbuilt my stands with the 2x4 frame plus skinning in hardwood and I was considering a less bulky approach. Maybe I am overthinking it.

We’ll see once I make the top box. If I don’t feel good about it not much lost and I have a couple extra nice plywood sheets for cabinets or whatever.
I’ll dig up your thread, I do recall it was quite informative and awesome.
 
They are I had 24 in my old 300 they slowly suffered attrition over time but the first 6 months was awesome such a great non aggressive fish addition, they did fight among them selves overtime and two separate groups formed.
 
Love the chromis. I’ve never had luck with them not killing each other off until this time around. I added an equal amount of anthias. I don’t know what it is about the anthias but it seems to allow everyone to live in harmony. Everything else in the background looks awesome.
 
Blue photosynthetic is every bit the nuisance that Xenia is. Here’s another pound of it for the month.

Are there any critters or fish that eat that stuff?
