Tideline Crystaline G2 Reef Internal 60x24 (130 Gallon)

Tideline Crystaline G2 Reef Internal 60x24 (130 Gallon) is the grandest system in the Crystaline G2 line: a huge 60 in wide, 24 in deep, 130-gallon rimless reef system with a massive footprint for showpiece aquascapes. It pairs a low-iron crystal display tank plumbed with a traditional internal overflow, a matching glass refugium sump, and a fully-assembled, USA-made cabinet stand. The internal overflow tucks into a back corner for simple, reliable plumbing. Want the overflow off the back glass instead? See the Reef External 60x24. Prefer a plain display tank? The Show Kit 60x24 is the option. Want a shallower 20 in depth? See the Reef Internal 60x20, or a shorter footprint, the Reef Internal 48x24.

What’s in the Package

• Display tank: 130-gallon rimless aquarium, 60 in x 24 in x 21 in, low-iron crystal front and side panels with beveled edges, drilled for the internal overflow.
• Internal overflow: a low-profile overflow box in a back corner delivers a quiet, silt-free surface skim down to the sump.
• Tideline Crystal Glass Refugium Sump: newly-designed low-iron glass sump with a built-in refugium section for filtration, media, and macroalgae.
• Fully-assembled stand: 36 in tall cabinet, pre-painted or stained in your chosen finish, side-access doors on both sides, controller-ready. No assembly required.

Built for Reef

• Low-iron crystal glass: ultra-clear tank and sump show true coral color with none of the green tint of standard glass.
• Massive 60 x 24 footprint: wide and deep, with maximum room for fish, rockwork, and coral growth.
• Refugium sump: room for a skimmer, return pump, heater, media, and a lit refugium to grow macroalgae and pods.
• USA-made stand: the 36 in tall stand is fully assembled and built here in the USA, with dual side doors for easy equipment access.

FAQ

How is this different from the Reef External?
Both are complete reef systems with the same 130-gallon tank, refugium sump, and stand. This Internal version uses a traditional overflow box inside a back corner. The External version uses the Ultra-Slim External Overflow on the back glass, leaving the tank interior completely open.

How big is the whole setup?
The display tank is 60 in x 24 in x 21 in and holds 130 gallons (the sump adds more total water volume). The stand is 36 in tall, putting the rim at roughly 57 in off the floor.

Does it come with a pump, skimmer, or light?
No. The kit is the tank, internal overflow, refugium sump, and stand. Add the return pump, skimmer, heater, and light you prefer, or ask us to spec a complete package.

Do I have to build the stand?
No. Every Crystaline G2 stand ships fully assembled and pre-finished. No flat-pack, no assembly.

Can I get a specific finish?
Yes, all 13 finishes are available. Because each unit is built to order, choose your finish at checkout and we will confirm the lead time.
