    hey there crew.was just wondering how you guys go about mixing RO & synthetic salt?alot of people airate the water,some let it stand for a few days etc........ok let me start.i usually mix my RO and salt in a 25 litre drum stir well and get my SG and temprature the same as my tank and then do my water changes.

    I wait a couple of days after mixing before i add the salt mix to the tank(3 days max) and only other thing i do differently is I make sure the new water is a degree or 2 less than my tank. The colder denser water immediately goes to the bottom of the tank and the warmer water obviously rises. Read this is great for airation and possibly stirring detris. Comments guys?

    I fill up an 80 litre container with RO, let it circulate for a couple days with a big pump in there, then toss the salt in, let it circulate for another couple days, then do water change.

    I just mix and add. Five minutes max.

    However now in winter I have to watch the temp as my RO drums stand outside and can get very cold.

    Not being an expert here, i mix salt for 24 - 48hrs with a pump and do water change.

    Alan you agree / disagree about the theory of changing with cooler water?

    I have read on this, it is basically used when massive water changes are done like 50% or more, then the water coming in is cooler and sinks and the guys then syphon off the top of the tank and collect the older water that way. But with regards to the other benefits i will take your word on that.

    I mix in a 50cm tank with a small seio in there, does a great job of mixing salt because the dispersed flow leads to less areas were the salt collects etc. I just add it slowly to the tank.

    so i guess theres no major negative impact of mixing to get correct SG and temp and then adding?

    This is probably the safest way to do it so if you already doing this why stop.

    I mix and add immediately as soon as the SG is right. Only difference is that I add the new water very slowly. With a clamped airline tube. Takes forever but no negative effects noticed yet. Once the syphon starts, I can just leave it till whenever as I normall mix exactly the right amount. I suppose this approach will be near impossible with large tanks. Water changes on a nano are easy.

    Guy's something else to consider here is checking the KH of the water before adding and buffering it if needed.
    Remember salt batches vary all the time, so what you used last month might be from a different batch if you bought new salt again.
    I mix the salt and RO in at the same time and let it mix for 3 days. I check the SG and KH the day before the water change and adjust accordingly.

    hi meks,
    best to make frsh r/o ,mix your salts,a good brand will dissolve in minutes.try getting the kh/sg closest to your tanks,not to worry too much about temp as you may be doing a 5/10 % change.drip into sump 1st compartment as the new water will mix in nicely,so when it hits the last uplift compartment the water does not enter the tank stressing everything out.temp will play a role sometimes as at diff temp you get diff readings of kh/ph/sg.

    Minimum at least an hour if I really need it. 5+ hours though normally.
