SRC Member kelstorm Posted October 20, 2002 SRC Member Share Posted October 20, 2002 hi, just want to hear from u guys, when u guys change water, (pls indicate the tank size) do u use the following methods and it does not include those chaps who buys solely NSW to do top up or change 1. using DI water with salt 2. RO water with salt 3. Tap water with salt 4. frequency of change? i use method 3 coz i find it more convenient than having to heave buckets of 'mixed water(either RO or DI)" and emptying them into my sump.. i simply pour salt into the sump and water from tap.. mix.. and switch on the pump.. hehehe.. with no corals inside, i can afford to change my water every 6 months to 1 yr...but i conduct water parameters check for my 4 ft tank every 2 weeks. ok.. above methods are not avocated but it sure helps to cut down time from 1 hour to 20 mins when replacing water.. and i get backaches each time i do that...

SRC Member Adrianli Posted October 20, 2002 SRC Member Share Posted October 20, 2002 Hi I use method 3 also. I change water only when I measured my nitrate level, to see if the level is high. Salt expensive leh. I change abt 50% of water each time, using half a bag of salt liao. I just dump half a packet of salt into my reservoir, mix with tap water for 1 hr. I then drain water in the main tank and then switch on the auto water top-up device. Quote Link to comment Share on other sites More sharing options...
Morgan Posted October 20, 2002 Share Posted October 20, 2002 I use method 3 before I switch to NSW. I mix 50 gal and circulate for half a day before it goes into the tank. No problem encountered using mrthod 3 but have to switch to NSW becos of cost. Quote Link to comment Share on other sites More sharing options...

Morgan Posted October 21, 2002 Share Posted October 21, 2002 Hi kelstrom I use to buy coral life saltmix in a box about $50. This will made 150 USgal of water. I posted the vol of my tank in another thread, anyway it more than 500 USgal. I currently get NSW by the truck load (~ 400 gal) delivered to my house for only $60. The water is not filtered, straight from the sea. Quote Link to comment Share on other sites More sharing options...

SRC Member kelstorm Posted October 21, 2002 Author SRC Member Share Posted October 21, 2002 sulphur-x, all u need is just a float switch.. and a pump and a small tank.. morgan, 500 USgal, how big is your tank? anyway, IMO, i really hesitate on NSW... with all the unknown stuff inside.. unfiltered somemore.. how u use it.. just dump the water straight in?

Hi kelstrom You guessed it.......... so far no problems accept that it take 4~6 hours for the sediment to clear. I used about 2/3 of the water and stored the balance. Anyway better get back to your topic RO/DI water. Quote Link to comment Share on other sites More sharing options...
