    Hi All,

    My 50 litre nano is comming along nicely and curently has the following stock;
    1. 2 Clown Fish
    2. 2 Turban Snails
    3. 1 Yellow tubeworm/feather duster (It ditched it's feather, but grew it back in about 2 weeks)
    4. 1 rock with purple mushrooms
    5. 1 rock with green/orange zoas.
    6. 5kg live rock
    The tank has been running for about 4 months now.

    I am however struggling with my water quality, even with a 8 litre water change at least every 2 weeks - mostly once a week. My parameters (Red Sea Kit) are generally the following;
    1. PH - 8.4
    2. Alk - Normal
    3. Ammonia - Not 0, but not 0.25. I would say it's about 0.12 (The colour on the chart is mustardish)
    4. Nitrite - 0.1
    5. Nitrate - 10
    6. Calcium - 400ppm
    7. Copper - 0
    This is causing me problems as I cannot keep any invertibrates - I have lost 3 red hermits and a fire cracker shrimp :(

    I have a protein skimmer, a hangon filter contraining Fluval Zeo Carb and another hangon filter containing ceramic tubes (I did this 2 weeks ago and the nitrates have come down a little) - both hangon filters are at about 20% flow rate.

    What should I do?

    Thanks

    Hey Dillon, please cross check your water parameters with another test kit, also try and do 10% water change weekly.
    You say your Alk is 'Normal', what is the actual value.

    The Red Sea kit doesn't give a true value - I'll have to try with a different kit.

    Would it be adequate to cross check with one of those "quick" test kits?

    These parameters don't look like they would cause the loss of inverts.

    How are introducing these creatures into your tank ?

    Well, slowly.
    Leave the bag floating around for a while, then let some water in slowly, slowly. Then generally I let the water out into a bucket and capture the creature in a net so as not to get any LFS water into my tank.

    The inverts last about a week before they die.

    if u using red sea kits, i would get it tested at a LFS, i got red sea and bought others as they were not accurate at all

    how long is "a while"

    i use the drip method and have had great results !!

    Agree with Warr, the parameters dont look that bad !

    you dont have a killer mantis of something lurking in there by any chance?

    About an hour or so.
    I'm going to get more live rock, get my water tested, wait a while and then give the drip method a go.

    Thanks for the input.

    Also, you don't mention the salinity as part of your parameters?
    What do you use to top up when the water level drops due to evaporation?

    IMHO this smacks of not acclimating the inverts properly.... for a shrimp, i drip for anything up to 3 hrs .......... that or you have a hidden killer in your LR ......

    I have a normal heater with a glass thermometer to verify what the heater is saying. The temp is constantly 25 - 26 as I use the "drip meathod" to get water back into the tank when I do a water change (funnily enough it never occured to me that I should acclimatize livestock in this manner).

    The salinity is 1.025 - 1.026 (it is with a floating type hydrometer, I know I need to get a glass one).

    I used to use tap water, but am now using RO water from exotic pets. My tank has a glass lid, so i try not to replace evaporated water as I replace 8litres of water a week.

    I think based on what everyone has said, I need to improve my habits...

    Or a refractometer.
    Anybody know where I can get one?

    Dude, out of personal experience try and get yourself a refractometer as soon as you can. I used to use the floating glass hydrometer and it always gave me a reading of 1.024. When I got my refractometer I was shocked to find out my salinity was much higher than that. Also ask your lfs what their sg levels are as this does affect the inverts especially if your sg levels are way different.

    So I finally started using RO water in my tank :thumbup:
    Also, I also got round to installing two 15w flourecent tubes (one white and the other blue) above the aquarium - although my wife is moaning that I have put the transformers in the glasses cupboard :)

    The tank is doing much better now!

    I have introduced 2 hermits - one got munched by the other one and 2 cleaner shrimps without any sudden deaths. My mushrooms are doing much better (I seem to be getting a new mushroom roughly every 2 weeks), and my zoa's which pretty much died (not 100% sure why) seem to be coming back from two specimans that I managed to save.

    Now, I just need to get rid of the bubble algae!

    Also, how do I take good quality photo's of the tank? I can't seem to get it right with my camera.
