After finally getting myself to go about it, I dug up a spare tank that I used to keep freshwater shrimps in.
Bought $15 worth of distilled water today, topped up the tank and added Oceanic salt. Used a hang-on filter with some biohome from my other tanks. I aim to add another hang-on filter for more flow and filtration.
Will not be using a skimmer. Nitrate & phosphate control will be via biohome, NP-biopellets, water change and daily siphoning of detritus.
So far with the lights on
