    Hey all,

    My tank is in its 4th/5th week now and although i used mature water when setting up, I know the tank must run for a while.

    I have started developing a green algae and its getting like grass. My turbo snails died. I don't know if that was as a result of coincidence or the water.

    My Zoas are doing ok and my Xenia is pulsing and growing well. Even the few mushroom frags are doing well.

    I added a sand star, lawn mower blemmie and sail fin tang and they seem to be enjoying the grass, but not fast enough.

    I also have bubbles growing on my rocks.

    Is this all just part of the normal cycle?

    yip and looks like the start of GHA, what are your nitrate and phosphate levels?
    what rock did u use? as it my be the source of your phosphates

    Hi Dallas,

    I'll recheck them tonight. I did a 75 liter water change on Sunday.

    I used 2 pieces of live rock from my LFS and the rest was base rock, also from my LFS!

    A normal cycle does not have livestock in it. Lights stay off during this period as well or you will end up with the algae as in your case. You dont have enough liverock to support the bioload so it all decomposes and just produces nitrate. This is the cause of the algae.

    All the wonderful info that no one tells you when you set up. These were times I was told to run the tank and the fish added was to cure the problems...

    Ok...where to now!

    Sunday was my first water change. I used 75 liters NSW. Also used NSW when I setup the tank!

    How do you use NSW if you stay in Brakpan?

    The fish will help keep the algae under control but its not the complete solution. You need to get the nutrients under control. From your specs you say you have an ATS etc? Is it running and is it growing algae? More waterchanges will help and should be done since your filtration system is under stress IMO. You need to build up a better bacteria colony to handle the nutrients. This will only happen over time. That is the main goal of the cycle period.

    BTW. The bubbles are oxygen bubbles due to the algae that are photosynthesizing. It is a sign that your algae is growing nicely.

    I brought the NSW back from Sodwana. We took it out of the ocean at 0900 from deep water, loaded it on the car and came straight back. Water was in the tank in less that 10 hours.

    The ATS is on and the pump is running. Algae is starting to grow only the past say 2 weeks. Picture below:-[​IMG]

    IMO? How often would you suggest the water changes? Should I add any other marine life to assist...My sand is also dirty, hence the sand star and hermits?

    Cool...

    what sand are you using and where did you get it?

    Sand in the Tank is Crushed Coral...Got from LFS

    Sand in Sump is Sea Sand...taken out about 20 meters in on low tide.

    dont add any more lifestock right now - you will only load your already struggling bacteria colony further. remember, the bacteria colony takes a while to multiply enough until it can deal with the bioload of the tank - hence the cycle. right now you are producing more waste than the bacteria can handle, resulting in poo water etc.... only once the colony has had time to grow to a size where it can handle all the waste being produced your nitrates will drop. when nitrates have been undetectable for quite a while should you consider adding more lifestock.

    for now try to change 20% once a week MINIMUM, that will help with the nutrient export.

    what lights have you got on your scrubber?

    also, back off a bit on the lighting period in your DT. your blues are on from 6am-9pm - it's a bit long.

    good luck! the only things to happen quickly in this hobby are shit

    To add to it...just saw my hermit grab eat my blemmie!!!

    I have 2 50W energy savers in the sump over the DSB and onto the ATS. Should I increase these. I think they are 5000k.

    What would you recommend as time for the lights!? My tank stands in my office so I look into it all day!

    What is your waterflow per hour and have you added pumps in the tank as yet?

    that 10hr trip will have caused decay in the water plankton etc and started to decompose and further the cycle when added to the tank, this is the cause i am sure.
    I would take the Livestock to someone to keep or the LFS, clean up the algae, let the tank cycle and make sure everything is perfect.

    also you are using old NSW to do water changes with, so you are taking out good water and adding in old sea water, rather let the tank cycle and when its done, start with the water changes

    I have a 3000 liter per hour pump through the overflow.

    Animalia...you added the pumps!

    I am thinking I may need stronger lights in the sump!
