the new guy Posted August 2, 2011 Report Share Posted August 2, 2011 Hi all. i havent been on here for a while. we finally have a new house to move into at the end of october so now i can plan the setup for my marine tank. i was just wondering how i could measure water accurately for the salt to be mixed in. whats going to happen if i put too much or too little salt in it? does anyone know of any marine keepers in Kaiapoi? :digH: :nfs: :sml1: :smot: :slfg: :spop: :gigl: :roey: :sml2: :smln: :thup: :yaw1: :yaw2: :an!gry &c:ry :dead%fish !drool: :dunno: :facepalm: :happy1: Quote Link to comment Share on other sites More sharing options...
Squirt Posted August 2, 2011 Report Share Posted August 2, 2011 B*H*W/1000=amount in liters. Using the inside dimensions of the tank( outside dimension minus two glass thicknesses sorry late night )(and one or two for the bottom/top) Quote Link to comment Share on other sites More sharing options...
the new guy Posted August 2, 2011 Author Report Share Posted August 2, 2011 O sorry i should clarify what i mean. I know the capacity of the tank. i just need to know a way to measure the water to put in the tank without using a measuring jug and doing one litre at a time lol :roll: Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted August 2, 2011 Report Share Posted August 2, 2011 Measure the tank width by length by the height you wish to fill it to then calculate the volume in litres, fill it and add the required salt. Quote Link to comment Share on other sites More sharing options...
the-obstacle Posted August 3, 2011 Report Share Posted August 3, 2011 As above. Also - to be sure get a refractometer to measure the relative density (salltiness) that way you'll always know you've got it just right. I bought mine from fish-street.com for about $30 and it was here in 2 weeks. Quote Link to comment Share on other sites More sharing options...
the new guy Posted August 3, 2011 Author Report Share Posted August 3, 2011 Well that clears everything up. so it doesn't matter if there is too much salt in there cos you can always add more fresh water?? i have got our skimmer from fish-street.com and found them helpful and reliable. just need to change the plug on things.

the-obstacle Posted August 3, 2011 Report Share Posted August 3, 2011 yep, exactly. The first fill you can guestimate based on the number of litres, after that do the same with the bucket/tank you're pre-mixing in and use the refractometer to fine tune. +fresh water - lower salinity +salt - higher salinity -evaporation - higher salinity, top up with fresh Quote Link to comment Share on other sites More sharing options...
