    ok the last 2 days have been terrible. my zoas died, had to gice my monty's to lanzo to look after, think my gobie has ich, im getting major cyno blooms. this green(lumo) type algae is growing, got bad brown algae and diatoms, my water has a wierd smell(i dunno if it's a sulphur smell or not)... please explain whats next?

    parameters:

    No2: 0
    No3:40
    Po4: 0.01 (tropic marine test kit)
    SG:1024
    P.H: 8.5

    last water change 4 days ago. 15%

    R.O water has tds of 2, no phospates or nitrates in R.O

    TS1 skimmer is working fine, got enough chaeto. carbon is fairly new.

    Nothing has died, sexy shrimp is still alive, starfish, hermits and all fish (5)

    running lights with just the 2 24w t5's for the moment to try get algae under control

    Wtf is going on? is there something i'm missing? besides more liverock

    Geoffrey - clearly there's some stress going on in the tank. I am not too sure, but the phosphates level might just be a BIT high at 0.1ppm. Do you run phosphate remover?
    Have something "changed" in the last day or so?
    What's the water temp like? Does is vary a LOT or little bit?
    Have the parameters changed in any way in the past 3 days? (for the good OR for the worse?)

    Have you added any lifestock in the past 3 days?

    the phosphates are 0.01 not 0.1

    yes got fluval phosphate remover. gonna make a phos reactor then adding seachem

    nothing really has changed, just bad cyno and algae! and my little yellow gobie has a tiny white growth on him, ICH? he's still eating though

    last fish i added was a clarkii clown bout a week ago, got from ferdie.

    temperature is constantly at 25-26 degrees.

    when i did a water change it went down to 24 degrees

    parameters have only been getting better. nitrates are going down slowly.

    hermits molted in the last 2 days.

    I just cant figure out this shit

    OK - Sorry Geoffrey.....

    Hhhhhmmm - really strange then... Could you perhaps post a pic of the cyano and algae? Have you tried blasting your live rock with a power-head or perhaps a turkey baster? IF not - can you perhaps please try? Let us know if you see crap coming out of the live rock? (This could be feeding nitrates, phosphates to the algae/cyano).

    Remember - the algae and cyano could be using the phosphates from the water, therefor it might not show us as being high on the test-kit...

    Also - perhaps get a 2nd opinion of the nitrates/phospates measurements - either from a fellow reefer who has a phosphate test kit, or your LFS?

    oaky. i've been blasing my rocks with powerheads everyday/2nd day for like 2 weeks. crap always comes out, but the tank never goes murky. most of it just settles back on the rock. dnt have a camera, but will try make plan this evening. cyno is growing on the substrate not much on the rocks. but the green lumo algae is growing on the rocks...

    2 different test kits give me P.O 4 readings of less than 0.1 or 0.01

    Ready to try the bacterial boost? :whistling:

    Perhasp it will be good to fuel the diatoms and blow them off everyday for a few days. They should take up allot of the shit and be removed by your skimmer eveytime you blow them into the water column...

    Geoffrey read the link below to get a better understanding of this algae.
    It also explains how to control it. ;)

    ok guys, my GF has a 'bathwater tank" and uses this stuff called heal all.
    it says its for ich, and good for marine tanks.
    my question is, is this a gimmic? does it work?
    hope this will help you geoff

    Geoffrey i was not going to comment because this subject (Ich) has many views. But i remember somewhere on masa they had a vote on treatment. And the one that got the most votes was good husbandry. I subscribe to this option as well.

    The fact that Zoos are dying really concerns me . You have more chance of croaking from phosphate contamination before these guys roll over. The fact that it has happened so quick makes me think that it is something you have added., maybe by accident.
    The first one that comes to mind is a kalk overdose. Although 8.5 would not harm a Zoo or fish your pH is still high. To safely maintain at these levels is difficult.. If you are intentionally doing this, is it possible that perhaps you have over shot your mark. Higher Ph can also irritate fishes gills, and would explain the hardier species like the damsel being stressed.

    Contamination would be a given , so by process of elimination could you not work backwards and look at what you have added in the last few days.

    Cyano should not be something to panic over. Admittedly grubby tanks are more prone, but there are few tanks that can claim to be cyano free 12 months of the year.

    Good luck

    hey, the tank is clean really. i live in the same commune. no additives at all. the only addition is a clownfish in the last week. other than that a water change.
    its very strange, we havent figured it out yet.
    everything was happy til the clown arrived. things looked good for a week and then in the last day or 2 went downhill.
    the water does smell a bit tho? sorta like sulphur, but not exactly that smell?
    pretty sure thats not good. we check and nothing has died. so not sure what is causing that. any help?
