    So, I'm doing a water change yesterday.

    Doing my salt mix in an open top 210L plastic drum. Some adjustment and I get the salinity just right - 1.024. I'm using a big circulation pump to mix the water comprising a 50mm flexible suction line and a 25mm hose pipe for the return. Pump sits on the ground ( a SS Lowara unit, pumps around 12 000L per hour, with a head rating of around 40m, one of those small industrial type pumps), both hoses in the drum.

    So with a properly mixed drum (around 180L), I turn the pump off and go inside to take the old water out the DT. 9x20L buckets later, I'm ready to insert the good water. Go outside, and WTF :(, someone has stolen my water. Bewildered, I look around and see a wet trail where salt water has drained off into my garden:nono:.

    The damn return hose has fallen out the drum, the suction pipe still inside. The hoses have siphoned the drum empty. Much cursing and swearing ensued !!!
    For the record, no :peroni::peroni::peroni: had been consumed at this stage.

    150L of good premix gone (R100+).

    Anyway, I painstakingly mixed up another batch and finished the water change.Then I cracked a good few beers :1:.
    Still got a bloody headache this morning ...

    Ouch! Just a question, do you make up the water and use immediately or let it settle for 24hrs or so before doing a water change?

    Would have loved to see you face....

    Anyway, why not just use a normal return pump. Just dump it inside, no hoses attached. Works for me.

    I mix 80L on Saturday, with small 300L pump and small 150W heater. Then do the change on Sunday.

    I pump it straight in. Its around 15% of the total system volume

    I dont have a spare return pump at the moment.
    I also use the lowara pump for filling from the drum to the DT.
    Pumps it empty in about 2-3 minutes.

    LOL I did something similar once but mine happened when my tank cracked in September last year. I used a powerhead with a pipe to circulate my sump water. I went out for an hour but switched the pump off before I left. A while later I received a frantic call from none-reefer that the floor by the sump is wet again. Thinking that this time the sump also cracked and that I will be throwing everything on the rubbish dump I raced home to find the one end of the pipe slid out and on to the floor creating enough suction to start a nice flow onto the floor. I had to deal with a very wet floor and a very angry none-reefer that evening. :(

    You're right! (And lots of spare salt)
    Fortunately I keep 400L of RO available most of the time. Otherwise I would have had to go lug NSW from the local beach.:whistling:

    Good luck for the plants that were down stream. The salt will cause quite a bit of damage to the soil.

    You're right on the garden bit.
    Fortunately, its mostly a section of grass that the dog tramples to bits as it chases monkeys etc.
    Was planning to install Duzi gravel/cobble stones in that section anyway.

    So now I've got another reason to expedite the above.

    Sorry to hear about the event:lol:If it's not :peroni: then it must be old age:p

    Also had a bit of a stupid day yesterday. Ran a pipe from my RO unit to my RO compartment in my sump to fill it up and forgot about it:whistling:

    What I do, and it's recommended by other gurus like Oom Hennie (Reefmaniac) as well, is to first heat up the RO, then add the salt as per manufacturer recommendations slowly and let it circulate with a pump for at least 24hrs for the salt to dissolve completely and stabilise. Check the salinity and adjust to the same as the tank's if needed, again waiting for the salt to dissolve. Then do the change.
    Doing this ensures less shock on livestock and you know that the salinity is correct :)
    For people who didn't know, always add salt to water slowly, not the other way around ;)
