So this is a journal for my new 120, which replaces my long running 75 gallon. For anyone who followed the previous tank, this one will be basically the same style with just a bigger footprint.

First planting, about 2 months ago.

Image



Tank

48" x 24" x 24" Marineland 120 gal


CO2

GLA Grow 1 regulator, 10 lb tank.

DIY PVC reactor. Main pipe is 3" x 24"

Image


CO2 cuts on 90 min before the lights, goes off 1 hour before. PH drops 1.1 by lights on, proceeds on down 1.3-1.4 at peak. Livestock are fine at this level, heavy flow and good surface agitation helps.


Filtration

Two canisters: 1 Aquatop CF 500, and 1 Hydor Pro 600

Measured flow combined is about 600 gph.

1 Koralia Nano 425 for added circulation

Both canisters have SunSun intakes with the skimmer

Left corner is the the Aquatop. Using a 1" outflow pipe to reduce velocity (the in-tank flow is crazy!)

Image


Right corner is the Hydor. The CO2 runs inline with this one.

^also you can see my LED night lights, mounted on each end of the main fixture.

Substrate:

Black Diamond blasting sand


Lighting

6 bulb T5HO hydroponic unit

Image


Bulbs are front to back:

TrueLumen Flora
Agrobrite 6400K
Zoo-med Flora
Plantmax 3000K
ATI Purple
TrueLumen Flora

Fixture is 9" above the tank, PAR at the sub is around 120. Having lots of red bulbs help keep it down, not to mention awesome color rendition. PAR would be a lot higher at this distance with more 6500Ks, for example


Ferts

Macros 3x week
7.5 ppm KNO3
1.3 ppm K2PO4
3 ppm K2SO4 (for 6-7 total K)

Micros 3x week
.015 Fe from csmb
.02 ppm Fe dtpa

** Micros are more now because Im rolling my own instead of using csmb. Will update the amounts once I arrive at the sweet spot.

50%-60% water change every 6-7 days

Livestock

25 Harlequin Rasboras, will soon get this up to maybe 30 or so
6-7 otos
Trio of young German Blue Rams, just coming into their adult colors
10-12 Amano shrimp


Here's the latest rendition. Plant groups are no way shaped for height or footprints. Mainly just tentative placeholders of where things are going to be. Have lots of ideas to try, and open to any suggestions! :)

Right side

Rotala Sunset. Currently in a rebuilding phase. This is 3 main stems, tallest one is about 16". Probably next WC will cut them apart and make a nice group

Staurogyne 'purple' on the right, Pogosteman erectus in back

Image


Ammania sp bonsai. Will expand this group pretty soon, have a lot more growing out in the 50

Image



AR mini 'variegated', Downoi, Lagenandra meeeboldi 'red round', Erio vietnam, Proserpinaca palustris (mermaid weed)

Image



Left to right: Isoetes lacustris, Rotala macaranda 'variegated', Oldenlandia salzmannii, Acmella repens

Image



Trying to figure out a way to snake the Ludwigia red more front to back, and keep it low. Right now is just a sideways cluster.

Willow moss sp gigantea on the smaller log, Pogosteman kimberly in back middle, Floscopa scandens to the left

Image


Changed the original Buces on the log. The other ones were smaller leaved greens and they werent doing so well. May need more traces, idk. Reason I liked them is because they bloomed profusely in the 75. Digging the red stems on these though, and the leaves I think are a better contrast. Gonna give them a month or two and see how it goes

Image


FTS

Other thoughts: Reduce the Staurogyne repens and shape it up differently. Currently just a big oval with no personality. Same goes for the Monte carlo in front of the log.

Bring the Stauro purple on down to the left in a bigger group

Thanks guys



Yeah I forgot to add this in the OP. It's 9" above the tank. PAR at the sub is about 120. It would be a lot higher if not for all the red bulbs.

I made a bracket out of 1x8s, painted them black. It just sits on the tank. The width worked out just right, easy to slide back and forth.

Not the sexiest thing in the world, but it works!

Hey burr did you place osmocote root tabs under the substrate? I'm assuming you did.
Not this time, but Ive added a few to certain things.

The Lagenandra has about 6 individual balls. It did better in the 75 when I gave it some. The AR mini has a couple balls under each plant. Again this is individual balls, not "tabs" full

Probably stick a few under the stauro purple when it's location is finalized.

Thanks.

4' is all the space I have too, or I would definitely have gone with a 5-6 footer.

Im loving these dimensions honestly, coming from a standard 75. The 24" depth front to back is really nice. The height is more than necessary but Im using it to advantage. The empty space up top makes it easy to blast flow without disrupting things too much.

Like if you stir a pot of soup from the top, the bottom starts swirling as well.

These look like crap honestly. Ideally the leaves are perfectly flat, no wavy margins. I tend to sell my good stuff and keep scraps to start over with. What you see above is the scraps.

Here's some better specimens, not perfect, but better -

Image



As for why yours are doing bad, idk. ARs in general dont like high micros, wavy leaf edges is a classic symptom. Could be 100 other things too though. CO2 being a usual suspect


Very nice! You always get such amazing colors in your plants. It gives me something to aspire to.
Thanks!

Color has a lot to do with T5s and bulb selection. It's hard to get a pop like this with LEDs, at least without dropping a small fortune.

'bout time...:icon_wink

Looking spectacular though! Killer plant health and colors as usual. Big improvement in the contrasts and distinction of groupings between initial planting and the current iteration.

Harlequin Rasboras were an excellent choice imo for the style of keeping the plants trimmed low with no back wall plantings. The Rasboras will inhabit the upper third and pop nicely against the bare black background, bringing visual interest to the unplanted area of the tank. Well thought out.

This so true and still funny. AC for After Crazy?

Burr, as a total newb I can only say, holy moly!!! Yours is an incredible planted tank

Thank you from all the remarkable descriptions. I came here wondering if this planted tank was possible. I didn't think so. Boy Howdy was I wrong. Stunning use of texture and color is outstanding. Vibrancy that makes want to be there in in my dreams as well as awake. Thanks for sharing.

Blasting sand is inert, yes.

Ive put a few individual Osmocote+ balls around a couple of things, but 95% of the tank has nothing.

Most plants can do just fine with only water column dosing.

Burr very beautiful tank. I never understood how can one make the red plant pop, ive keep red species plant and all i could turn them rust red but not bright red. Any secret hiding there?
No secret. Healthy plants is the first thing. Then you need a light with a good amount of red.
