So my Arowana died last night and I am considering converting my 180 gallon fresh water tank to salt. I need some help in what I would need to complete the transfer. I have done some looking around and the information all seems kinda scattered and I am a complete newbie to marine.
This is my current equipment:
180 gallon NON drilled tank.
1 FX5
2 Eheim Pro 3 G160 Canister Filters
2 Koralia 4 power heads
Black Tahitian Moon sand
3 10 watt LED flood lights
Now, providing my tank has been cleaned and lets assume this equipment is squeaky clean from any previous fish, could I get some pointers on how to go about the conversion? Is the substrate still good? Do I have to convert to crushed coral? etc...
Please take me from the top as this is my first foray into marine and I want to do it right. I'd like to re-use as much (if anything) as I can and do it once, but do it right.
