    sad day today.

    went back home. see the tank very cloudy and strong smell of rotting fish. seems like 3/4 of my livestock up lorry. and rotting. i recently changed my OHF filter to a canister filter. i moved the media quite fast. and didnt think any BB die off was alot. first few days was fine. until yesterday nite when i saw 1-2 fish swimming up to the surface. i arranged my rainbar as such the water level is above it.. my planted tank is arranged as such as i see no problem with it. so i wanted to know what could have happen to cause the "crash".

    very sad. among the casualties: coral beauty, blue ringed hermit, a tube worm i got since the start of the tank, 1 green chromis, two other damsels, and 2 cardinal fish

    the tank is at least 6-8 months old. very "cycled"

    my suspects:
    1) BB die, den ammonia buildup to very dangerous level
    2) insufficient air, causing fishes to gasp for air and die causing the chain reaction..
    3) filter got poison or residue from the manufacturing process and started poisoning everything..

    also, taking this experience as a chance to better myself. i would like to know how to remove anemone like organisms that are spreading throughout the tank like weeds.. wat causes their growth? also, i would like to keep some "simple" corals. any addictives i need to add? as currently its just a fish only setup..

    Quite sad to read about the loss. The use of OHF or even canister filter is not the right way to start a marine setup. I had advise you previously on this thread-http://www.aquaticquotient.com/forum/showthread.php?t=29306

    I would say that you have a total loss and would advise you to throw away the live rock that has the anemone like organism on it. No use keeping the rock for a new setup. Get rid of the sand too.

    Get a proper setup. A tank with overflow ( internal or external, it's your choice ) and a sump with a stand or cabinet. A small tank can also look good if it's properly setup.

    For equipment wise, a good skimmer is a very important piece equipment for your setup. If you are aiming for corals, a chiller is really needed. With a chiller, the type of lighting to use will expand from using High Output T5 to Metal Halide lightset. A return pump that matches the flow needed for the chiller is required too. These are the basic equipment to have for a tank that has coral.

    Accessories and additives.
    In the future, you might need a phosphate and carbon reactor. The phosphate reactor to remove phosphate and carbon to remove whatever toxin in the water column. Certain corals gives off certain chemical to inhibit other kind of coral to grow. If you are on a budget, weekly water change is another option to go for instead of purchasing the 2 reactor and media.

    You'll also need to dose calcium and kalkwasser. Certain salts does not have adequate level of calcium so you'll need to increase this to a certain range. This should be done during lights on period and should be turn off before lights off. Kalkwasser would be used in conjunction with an auto top-up equipment to maintain the level of calcium during lights off. You could either get a dedicated auto top-up equipment or diy one. Either way, this will maintain the water in the sump level. To manually dose this 2 additives, you'll need to purchase them in powder form. The use of test kit is important too to find out the level of calcium in the water. There are other additives to add on too.

    If you want to start over, do it slowly. Read up more. Stock up real slow.

    hi bro,

    thanks for the advice. really helps. will change the liverock and sand. but would that mean i have "re-cycle" my tank?

    the reason i'm using the unconventional cause it seems weird having a 2ft tank on a 2ft sump. i'm just testing water and learning the basics before i move on to 3 or 4 ft tanks which i'm really looking forward to have.

    but now, budget wise. its very tight so i have to content with a simple 2ft setup.

    thanks again bro.

    It's not weird at all to have a sump the same size or even larger than the main tank. It helps to increase the volume of the water as well as provide an area where most of the equipment will be placed.

    But if you would want to continue with the current tank, weekly water change is a good option to look into.
