RO/DI water stands for reverse osmosis, dionization. You only REALLY need ro/di water if you are doing a reef tank. RO/DI water is tap water that goes through steps of purification to become pure water with 0 tds,nitrite and nitrate. It is perfect for reef tanks because it doesnt contain any chemicals that algae feeds on and the corals love it, especially SPS. You can purchase RO/DI water offline at some LFS but not all of them. It is fairly expensive because it sometimes takes 3 gallons of tap water to produce 1 gallon of RO/DI. There is also maintenence that you need to do with a system ie: filters need to be changed etc.Do I need it, Why do i need it, What do I use it for, Can I buy RO/DI Water offline or do I need to buy the RO/DI Water systems to obtain it?
Yup. The bacteria on the piece of LR will die off creating an ammonia spike which will cause ammonia eating bacteria to grow and start the cycle.Dead rock just means that it's rock that used to be live... Sometimes it has dead bacteria in it that has to cure... Meaning basically you'll have an ammonia spike from the decaying bacteria.. If I understand that correctly?
I purchased a bunch of rock from Marco Rocks and he shipped it all and I had it by the end of the week.
I quick search will bring up his website
