Sharing my first 120P aquarium and hoping to obtain feedback and guidance as it progresses.
I purchased the ADA 120P tank, AFA stand, mat and ADA substrate set from AFA in San Francisco. The set cost approx $2,000 including shipping. The set arrived as a set of boxes on a pallet which was loaded into my garage by a local delivery service using a small fork lift. The delivery process took approximately 4 weeks.
The substrate set included one large bag of ADA power sand, the three ADA additives - bacter 100, tourmaline and super clear, five bags of Amazonia 2 regular, and two bags of Amazonia 2 powder.
The tank is 120 x 50 x 50 cm, so roughly 48” x 20” x 20” and holds approximately 80 gallons.
All items arrived in excellent condition. Helpers and I moved the items to the basement. The stand was easy to put together. Plywood based. Sturdy. I drilled some additional 4” holes in the left side and rear panels for access. I put down the mat, and added the tank.
I chose a chihiros 1200 wrgb2 pro light. I hung an IKEA adjustable rod holder over the tank to suspend the light from which has been working out well for my tanks.
For other mechanicals: these have evolved since initial setup
I’ve attempted to include some photos here but they don’t seem to be being pulled in.






The hardscape for the tank was selected collaboratively with the team at cuboid aquatics in Pipersville, PA. I became aware they carried a wide range of hardscape including the WIO product line and they were within driving distance (6 hours), so I drove down and spent the next day with them. They were well stocked and were incredible people! Their lead designer Maddie lead the effort. The design uses large WIO black venom and jade rocks to support a hefty set of Galapagos and WIO Centurian wood. I packed up the hardscape, brought it home and put together the current design. I chose the larger Galapagos pieces as I liked the dark highly contoured lines.
The design is a triangular layout as the tank will be viewed from the right side as well as the front and we wanted to keep that right side looking similar to the front.
The left side and rear are filled with the ADA substrate set. In two areas just in front of hardscape there are areas of substrate set where I intend to plant dwarf lilies and crypt spiralis tiger. The remainder of the front and right side uses WIO Everglades riverbed which includes tan sand, pebbles, twigs, leaves, and cones. I also added WIO black venom and jade pebbles and twigs.
My friend and I primarily used seachem epoxy to epoxy the hardscape together. It was easy to use. It does put off quite an odor. We also used a glue product call R6000 which seems to have worked out quite well. The tank has been in water for two weeks now. Some of the putty connected to wood has come loose. Best I can tell the R6000 joints are holding.
This is the current layout and you can see there is the normal whiteish “stuff” growing on some of the driftwood.
My friend and I filled the tank and started up the equipment to check for leaks and flow. We encountered a few small issues that were quickly resolved.
In 1-2 hours it was obvious there were loads of tannins in the water. I had read an article on cycling on 2hr that suggested turning off the equipment, letting the hardscape soak for 48 hours, draining, refilling and restarting, so this is what I did.
Once I had that new water……
Oh, water here comes from RO water normally remineralized with APT Sky up to a TDS of 100-120, however I had read that it’s best to make sure.KH is present to support the cycling process so this water was remineralized with APT Sky plus to a KH of 2-3.
To help boost the cycling process I started with Microbe-lift gel filter inoculation in both canisters, and Microbe-lift Nite-out and special blend products.
Water tests show that two weeks in I have high ammonia and nitrite. Tank is running with no light.
I did start up the co2 reactor as I’ve never used the horizontal yugang reactor and wanted to see what sort of co2 levels I could reach. I measured 40-50 ppm with the Hanna test set which is great and turned the co2 back off for now.
I will continue to monitor ammonia and nitrite near daily.
In the mean time I will be working on a planting plan.
Please get back to me with any comments, suggestions for sustainability, improvement, etc.

For other mechanicals: these have evolved since initial setup
- Oase BIomaseter 2 thermo 350 canister filter loaded up with seachem matrix, seachem matrix carbon and seachem purigen.
- Cuboid aquatics UV disinfection unit.
- Oase Biomaster 2 850 canister filter loaded up similar to 350 and with all pre filter stuff (outer housing, center pipe, pads) removed
- Netlea pre filter
- ARC small acrylic yugang horizontal reactor
- five pound co2 tank
- CO2 Art pro CO2 regulator
- soft, gray silicone 16/22 hosing used throughout
- two sets of quick disconnects for the hosing
- Jardli glass Lily pipe outlets
- Hydra aquatics stainless steel inflow with skimmer
- some inexpensive motion sensing led panels for light within the cabinet
- two kasa smart plug strips
