    1 kenya tree coral
    1 torch coral

    ph - 8
    nitrite - 0

    What lighting is over the tank?

    Pumps and equipment
    return=reef octopus water blaster 7000l/h

    skimmer = reef octopus rated at 1500l
    deep sand bed in sump
    macro algae in sump cheatamorpha
    running carbon in a sock
    running seachem phosphate remover in sock
    Maintenance
    I do maintenance alot as this tank is the main feature in my living room and the algae keeps on growing and growing on the rocks substrate ang glass panes, the glass panes need to be cleaned at least once every 2nd day otherwise it gets realy green.
    I also have an other pump conected to a hosepipe which i use to blow clean the substrate and under the liverock
    I did water changes monthly about 90 litres as I only have limited stock at the moment I dont see it nessasary to do more
    Other info and photo's.
    O.k I am starting to doubt my ability in maintaining this tank I realy put a lot of time and effort in this tank all my spare time goes into it and I love the hobby I just need to know exactly what I am doing wrong I had all this deaths but they dont happen all at once first it was one turbo snail after about a week the next one then the urchin went into the overflow where it died, I went away for a weekend and when I got home all seemed to be well the next morning I woke up finding the yellow tang had passed....I am limited on money at this stage and did everything I was told I spent most of my money on equipment hoping the system will run perfectly, but it looks like im missing someting.

    I dont want to keep buying livestock and let them fade away beacuse it impacts the enviroment and it costs me a :61: load of money. I am trying to stock the tank slowly but I seem to get nowhere when my livestock only lasts 2 months

    I also replaced my RO unit filters (got them from Marco)

    I do not overfeed (Feed flakes 3 times a day and once a while give them frozen food)

    My lights is on for 10 hours a day and all lights is new

    the algae that is growing is a light green algae and looks like hair algae as it gets quite long about 3cm before I scrub it

    My corals seem to be doing verry well and growing good

    Another thing I just want to add is the powerheads are all facing forward and not blowing on the substrate beacuse of the torch coral I dont want to blow it away.....

    I also have about 35 kg of liverock, I dont know if this will be a concern but I have verry limited livestock so I think its sufficient for now

    The 1st thing that comes to mind is you'r water parameters...
    especially ALK, MAG and CAL... you need to test for MAG and ALK also... the 3 are interlinked...

    Hopefully someone with more Experience can help you with you'r current problem...hope these help steer you in the right direction till another Member can give better advise and pin-point you'r problem...:blush:

    Snails could have been eaten (hitchhiker crab in liverock), hermits could have tried to steal the snail shells depending on their size. Did someone feed your tang while you were away? Blue chromis are notorious jumpers if stressed (bracing tank with eggcrate helps keep fish in).

    I added brightwells phosphate-e the previous night before the tang died but underdosed to be sure not to cause harm can that cause the death

    Yellow Tangs are susceptable to certain phosphate removers, not sure if this applies to brightwell products. Was the protein skimmer running when you dosed?

    Yes it was running and I added it next to the skimmer as described on the instructions well since I added the tang it never had any problems and I had it for about 2 months but I never dosed the phosphate e in the time I had it exept the night before it died

    Could just be that Tangs dont do well after most phosphate removers are added. Some phosphate removers have been taken off the market due to this.

    Sorry to hear about your losses. It always sucks big time.

    Firstly I seriously doubt it Phosphate - E , I have used it numerous times in varied setups as a temporary fix, to no ill effect whatsoever. As long as you took LR displacement etc into account.

    Your Ca is quite high and the pH obviously low , also worrying is the fact that you dont have an Alk test kit ,which makes me doubt the correctness of the other related params . What test kits are you using BTW?

    As a whole most of the deaths can be explained by plausible situations as the guys mentioned but the fact that you have some algae issues still point to nutrient issues which you should address through regular WC etc as the tank is still quite new.

    I understand the budget constraints but maybe twice a month water changes will help already

    OK yes maybe I will do more water changes to test if it works will also get myself a alk and mag test kit as I am quite far from a store that sels marine suplies what else would you sugest to get to stabalise the ph alk mag ect so I can get everything needed in case of someting going wrong I use salifert test kits and they are all quite new

    Thanks butcherman that clears things up a lot I did not overdose but as you said my phosphates is undetectable which means I should have never added the product...

    Just thought it will help with the algae problem in the tank...

    So I think that clears up the tang death.

    Im not saying its certain, only a possible cause.

    Rather focus on good water quatlity.

    Instead of spending money on fancy removers spend it on Water changes will be cheaper. only once an good water change regime becomes insufficent consider dosing addatives.

    Like Fransny ask any reason why your CA is so high? what salt are you using, are you adding any Ca adatives?

    Not adding any aditives exept that one time phosphate e and running carbon and seachem phosphate granuales other than that all natural I don't know what causes the high cal I use seachem reefsalt since the tank has started up that's why I think I might need something to increase the alk but will test first just want to know what's best to use beacuse I can't realy buy test kit test the water and then drive all the way back to buy someting to get the readings right but I guess you can't buy anything if you don't know what the readings is ;)

    This brand i believe is notorious for high ca levels. For a tank like mine that is sps dominated its great.
    What other salts are avalible to you?

    Hi Philip,
    If you desperately need supplies (ie test kits etc) you can PM me and I could perhaps send the stuff with my husband. He works in Secunda during the week. We could arrange for you to pick it up from him.
