hi all . i slowly start to convert my 20g to saltwater ( maybe FO maybe FOWLR )
1-is it important to use only one brand of marine salt ? or i can use diffrent ones together ?
2-how can i check and control the density of mixed salt with water to know if i m doin it right (beside what on the salt s box says)? is there some kinda test for it ?
3-every day bout 2 liters of my 20g tank water vaporize ,should i add tab water only or add mixed salt/water to keep the level?
4-the LFS said they can bring me sea water , and said it s much better than any mixed water , are they right ? should i go for it ?( oh it s too expensive ! )
5-i was thinkin bout a 10g sump with an in-water skimmer in it and some areas for activated carbon ,rocks , ceramic rings , bio-balls and ... which media is better to use or i can use all together ?
6-the LFS said the out-water skimmers are better than the in-water ones , wich one should i go for ?
these are the most important Qs i have in mind till now ,any other suggestion and advice will be most welcome
