I decided to take the plunge into saltwater. I picked up a 38 Gal
tank kit. I'm filling it with deionized water. I have 20 lbs of aragonite substrate, plus 20 pounds of aragonite live sand.
So far, I added the "dead" aragonite, and I'm in the process of filling up the tank (it takes trips back and forth to my DI
Once it's filled up, I plan on adding Instant Ocean as well as turning on the electronics (HOB
filter and heater) and stabilize the specific gravity/salinity and temperature. Then I'll add the live sand as well as order a live rock (maybe 20 lbs?). Finally, after that is fully cycled (should I add some ammonia to help?), I'll add a fish.
My question: If I'm using deionized water, do I still need to treat it with a conditioner?
Eventually, I will be upgrading to a canister filter. Hopefully my HOB
filter will be ok until then. I also plan on getting a skimmer when I add some livestock down the road.
Is a powerhead recommended for circulation? Maybe a 500 gal
