Getting a tank thread started for the Mariner 70. This tank is gonna be LPS dominant with peaceful fish. I'll put any fish in here that are too small for the 225g tank.

The tank is still getting put together in some ways, but most of the equipment is on it. I'm still planning to add another powerhead, change the lights (the Orphek Naturas are in, but I'm waiting for the mounting hardware), add a lid, etc.

No corals yet, but they'll be added soon.

I'll take a picture soon, but at the moment, I'm fighting off a cyano outbreak.

I'll add more details later.
