Acrylic 30g Rimless Frag Sale Tank

Making this for a local club member for an upcoming Frag Fest

It's about 36 x 24 and 8" deep in the inside, all walls are 1/2", back and fence are black, bottom is 3/8" black. I made a few others like this using 3/8" walls and 1/4" bottom, and those were OK and are still being used, but being rimless they did seem a little flimsy - easy to twist, and definitely not for everyday use. This one should be much better. Made to hold a Maxi-Jet (Cobalt MJ1200) in the rear chamber.

 

I also flipped the orientation of the pieces - the front/back/fence are bonded to the end. Normally you would bond the ends to the front so that the front panel is seamless across the front (i.e. you don't 'see' the end of the side pieces on the front corners) but after doing 2 tanks the other way and screwing with trying to get the fence perfectly square and spaced just right (hard to explain) I just opted to do it the other way.

 

Haven't updated this in a while. I finished off this one and built another since the last update!

Then I polished it all up





Back chamber for filtration



Overflow (needed to make this deeper so the water level is not so high in the tank - oops)



Hole for pump (MJ-1200)



Polished & rounded corners

 

I also make a frag rack system, stackable 1" / 2" / 3" racks, 6.5" x 6" with 34 holes at 1" on center, 7/16" each (for Oceans Wonders frag plugs, or any other) and a stack holder. Each rack system fits in a 5 gallon bucket, and 5 of them fits perfectly in the tank. I have 4 local club members with these tanks, all 4 of them were at out last Frag Fest this past weekend, and 3 of them with the frag rack systems also!







All different stacking configurations



In the frag tank

 

Got 3 of these sitting in my garage, just need polished up (one is sold)

 

Rounding with either a 1/8" or 1/4" roundover router bit. Next if there are a lot of inconsistencies I use a heavy grit sandpaper to get the general shape consistent, then switch to lighter grit to even it out. Then wet sanding with multiple grades of paper starting at 400 and going up through about 2000, then 3000 wet/dry sponge sandpaper (from auto store) followed by a pass with a Black & Decker random orbital buffer and Meguiar's polish. I'll probably take some pics of the next time I go through this process

 

Don't let me forget about you - busy weekend (tank maintenance up the ying yang) busy work week ahead also

 

Oops sorry I forgot to get back to you. It's been a rather hectic few weeks!! I'll reply to your PM shortly

 

I don't have any done, not sure when I'll do another batch. Shipping is rather expensive, and I haven't had time to dig into different methods that might be cheaper.

 

I sell these for around $300, then the frag racks are a stack of 3 with the base carrier for $35 per set or $150 for a set of 5 sets (which fits perfectly into the tank)
