Waterbox 3620 rimless build

The light is now pretty much finished. My plan is to have the cords run behind the tank so I mounted them towards the back of the fixture. Unfortunately their weight now tips the fixture up in the front quite a bit. Hopefully a few lbs of lead shot in the front of the housing will do the trick. Pics:






As you can see I also added one of those cheap LED strips that you can find on eBay for just a few bucks. I'm hoping it'll make a decent moonlight. If it ends up too bright, I'll black out a few of the LEDs.

I also finished puttying up the stand and finished the back panels. The left side is hinged so I can get behind the stand--the plan is to put this against a corner wall.

A little more progress. Tank is in the house and frosted back done. I'm extremely happy w/ WaterBox's build quality:





Here's the tank / location it'll be replacing:



Stand's almost finished and now in the house as well. Just need to install the front doors and move the old tank out of the way.

And a bit more progress:

My auto dosing system is pretty much done. I'll be running 2 needle valves off my regulator, feeding in below the 2 solenoids. Solenoids will open on a timer after dark for a few minutes and fill the bubble counters. Co2 will then turn on in the a.m. and push the ferts into 2 RG reactors and into the tank:

what an interesting way to do autodosing! I would have never thought of feeding them straight into the reactor! doing it this way would prevent any back pressure from reaching the ferts. do the solenoid stand up to the co2 pressure?

Yes, beautiful tank build! and very nice stand, I like the color

Hey, thanks! The solenoids are NC and can handle 125 psi so more than enough! Path of least resistance should ensure gas only goes into the reactors anyway. My only worry, as I haven't yet tried this out in real life, is will the bubble counters fill easily and consistently enough, and will the level of the fert solution in the bottles have any effect on that? I know the gas in the lines will easily compress and make room for the liquid, I'm just not sure exactly how much they'll fill and/or overfill into the lines after the counters. There will still be check valves between the reactors and the counters, so hopefully their resistance will be enough to stop the flow at the right point too. I'm just going to use a cheap 15 min timer to start but if I have to I'll get a fancier digital that I can dial in by the min or second.

My goal w/ this was 1) cheap 2) minimal moving parts that won't break down or get clogged, and most importantly 3) no lines coming up and over the rim of the tank. I really hope this will work, but if not, I'm only out about $40 in parts.

Let there be light!




I also added a little pull out shelf for holding things during maintenance:

Picked these up today too, $115 later. That's a bit over 70lbs--floor tiles are a foot wide for reference. I have another ~40lbs in my 29g that I think will make it more than enough for this scape.

Yay or nay? I still have to add some manzanita, more soil and some rubble.
