Should I go for Sand or crushed coral
+1^Sand
Thanks for all the information now my second question can I use same water from my fresh water or do I have to carry new water to start my saltwater tank
A thin layer of crushed coral can be aesthetically pleasing and easy to clean with a turkey Baster and large water change. I think this is for your 2g jar or something right? If so clarify as most people on here run large systems and may have experience mostly with large systems. I run crushed coral on all my Pico tanks as you will want to aggressively pour water into the sandbed weekly to flush the system of sediments as most picos don’t run filtration. If this is for a Pico and you want questions answered specifically for a small tank nano-reef.com tends to have more insight.
Here's a good place to start:Mmmmm that's alot off water hahahah
First time I heard raw shrimp hahahaha
