    Hi there,

    I'm very new to this hobby, so apologies for the many questions!

    Instead of investing up front in an RO unit and buying salt I'm considering getting water from an alternative source. I will probably get an RO unit eventually, but can't buy everything all at once.

    One option is to buy the water from an LFS (at around R1/l), or getting it from the 2 Oceans Aquarium as a member benefit (Members – Two Oceans Aquarium Cape Town, South Africa)

    Is anyone currently using this option and willing to answer some questions?

    - What is the water quality like from the Two Oceans Aquarium for use in your own reef aquarium?

    - Would I be able to use this water directly for starting a new tank? And then also continue to use it for partial water changes after the tank is established?

    - Can I store this water in plastic drums, and for how long before I use it?

    - Does it need to be treated with an additive of some sort?

    Any other alternatives? I read that some guys harvest their water from the ocean, but I don't particulary want to wade into 2m deep freezing cold water :)

    With regards to the 2OC water - if you run a quick search on the forum you will find tons of info and feedback on it. I wouldnt use it....

    ps. Welcome to MASA :D

    I concur, I made a switch from 2OC water to SSW about a year ago and I will never go back. My tank has dramatically improved since. My key problem at the time was with high P04 levels amongst others..

    Thats besides the slep of carting 25l drums around..

    There is a simple answer regarding to the use of 2OceansAQ water.

    Go and look at their reef tank! If you want a tank like that, go for their water.
    The water comes out of the harbour basin. That is reason enough for not using it.

    Now that you finaly bought my friends tank, I am willing to help you with a fast set up. But only if you understand why you have to do what I tell you and only if you do exactly what I say. Otherwise it might go the wrong way. I know tanks where the reefer itself doesn't have a clue what he is doing. But he does exactly on schedule what he is suppose to do. And these tanks look fantastic by the way. You can ask Zombie_CT what he thinks about how I do it. Then decide.

    I can for sure say, for a year I've been using water from the research institude, not a trace of algae, eventually something went wrong there, i was forced to change to NSW from 2OA, ever since been battling with green hair algae, invested in RO and salt, cant get rid 3 years later.

    A bold statement to make, but that was my experience ???

    Thanks Henk, I did do a search, for the keywords 'two oceans', but couldn't find much. I was probably searching for the wrong thing!

    You wouldn't use it at all, or will it be ok to get my tank started during cycling with just live rock?

    I use NSW most of the time , but dose it.
    A huge advantige for a algea free tank it topping up with R.O.

    But what works for one doesnt always work for another.
    Safest way would still be Salt mix with R.O

    Thanks for all the comments everyone, sounds like I should stay away from it.

    @LuckyFish Probably a bit off-topic in this thread, but I'm open to any advice, and I'd prefer understanding why I'm doing something rather than just doing it. I'll chat to Zombie_CT, I need to talk to him anyway to sort out transport of the tank.

    Hi all,

    I have used 2 oceans water since I started and have always had verying degrees of algal blooms. In fact not so much blooms but constant massive algal growth. I have continually improved my system but no diffirence. I collect water for about 3 water changes and by the time I do the last one the water is about 2 months old. I was about to do a water change with the last lot of water yesterday but something made me test the phosphates. It was through the roof (10). So threw it away. Not sure what now though. Want to try ssw but need to find a supplier with reasonable prices.
    Any suggestions.

    Hi, By dosing i mean:
    We have it filtering through a filter at all times with a heater and check alkilinaty and use the correct buffer for that and p.h .
    We also add a calcium .

    From there we check and dose the tanks with all the Iodine/magnesium and trace elements the corals may need.

    we are also back to using Green water for the corals.

    Why dont you try our water for a few changes and see what you want to do?

    Good luck
    David

    I stared up my tank with TO water and it ran for two months before my overflow gave up on me but i never really had a bad algae outbreak, only my back pane was covered in algae but that the fish took care of.

    Hi , i read you use it allready , but we sell 20 bottles in a tray and is R20.00 per tray...
    We are still experimenting on haw long the Phyto will stay in the bottle, so i might be doing batches of 10 in the future.
    We put one bottle per 200 liters per day.
