Hi I am new to salt water, had fresh water for years. I really love a good challenge, and I can tell you for me, I really want to do this with tap water. I will have a filter on the tap, and i will be treating my water, and letting it sit for days on end before i do anything. I have read both negative and positive about tapwater. Many people have great luck with it. Im a very patient person. The new tank I will be starting is a 29 gallon bio cube. My question is, do you have any experience with this? I just want to ad live rock, live sand..all the needed treatments, top with distilled water, make salt water using filtered tap. A few fish, maybe a coral or 2...R/O would be to expensive an investment for me, as I have a house to pay for, taxes, you name it. I also have a water bill, so I need to keep that way down. They tax the heck out of us here in New Hampshire, its crazy, so cutting corners is a must. I will test and retest, and bring samples in for testing also. I do not jump into things, ive been doing alot of reading. I have the tank here, and it will sit in the box till I am comfortable with all the info. Thankyou!...
