What do you think ? I started my first ever saltwater tank 2 months ago. Before investing in a rodi unit, I wanted to test with tap water, since it had low/medium TDS (about 80 ppm).
So I set up the tank with tap water, dechlorinator and Red sea coral pro salt mix. I added 2 clown fish after cycling, and 1 Bali green slimer 2-3 weeks later.
Fast forward a few weeks later, the Bali green slimer is not happy. I tried a different spot with less current, less light, more current etc. By then I was convinced it was not happy with my tap water.
So I bought a rodi unit and first did a 35% WC with rodi water (0 ppm TDS). The green slimer was still not happy. So I decided to go all the way and do a 100% WC. I slowly acclimated the fish and green slimer with the new 100% rodi water before putting the back in the tank. Since I ran out of Red sea coral pro salt mix the day before, I used my new Red sea blue bucket salt mix to make this new water. I figured it would be better for the slimer, and less expensive for me. I’ll stick with this for now.
So here’s a picture of the Bali green slimer when I first got it 3-4 weeks ago, and today after spending the night in the new rodi water.
What’s your verdict doctor, will it survive ?
A few days after I got it, in tap water.
Today, about 15 hours after the change to rodi water.
