I really hope someone here can help me identify the source of my problem so that a solution can be applied. Sigh...

I am thinking there may be some remnant toxin or harmful elements so hope this intensive water change exercise can remove or at least dilute the harmful element. Whatever it may be... In 2 weeks time, i estimate i would have changed approx. 70% of my tank water.

yah, in the process of raising cal n mg now. Also doing intensive water change of 2 x 10% per week. Using distilled water. I m using hanna po4 checker n salifert no4 test kit. For the past few months, po4 is usually 0.00ppm. Sometimes 0.02 or 0.03ppm. No3 used to be about 10 to 25 ppm for last few months. This week drop to 2.5ppm due to the intensive water change. Thinking of getting a starry blenny to help eat off the algae.

I tried monti caps, digitatas, birdnest all cannot.

Yes, i m monitoring all the params very closely. The above params are quite stable for the past 2 mths. Except for no3, which used to be more than 10ppm. Only last week then i managed to bring it down. Kh has been around 7.7 to 8.6 dkh for the past 1 mth at least. No big fluctuation. Changes r due to water changes and my deliberate attempt to bring down from 8.6dkh to closer to 7.5dkh. Cal has been around 370ppm throughout. I am aware it is not the low side. Will bring it up soon. But would this calcium level be the reason why i can't keep sps?

Bro A. Quarium, do post pics when u set up your cuttlefish tank. My tank is 4ft(l) x 1.5ft(w) x 2.5ft(h)

For cal n mg, i m dosing magnesium chloride gradually now to raise mg. It was 1170ppm initially. Will raise it to 1300ppm. After that, i will dose calcium chloride to raise calcium. For now, my cr is able to maintain kh n cal.

Dosed some phosbuster more than 3 months ago. Tat was when my po4 was at 0.55ppm, before i got my fluidize reactor to run rowaphos. Stopped using tat now. Also dosed nualgi abt 2 months ago due to cyano outbreak. Stopped for a month also.

1. Oh, yes, i forgot to mention chiller. Running hailea hs-66a. 1/4 hp. Set at 26 degrees c. 2. Fishes: - 2 black clowns - 2 dunno wat clowns (shd be common) - 1 mandarin - 1 blue damsel - 1 royal gamma - 1 swalse basslet - 1 sixline wrasse - 1 purple tang - 1 dunno wat tang (looks brown) - 1 white tiger goby (may be dead already. Haven't seen it for months) So far only 12 fishes actually, assuming the goby is still alive. Intending to get a few more to make up to 15. Feeding pellets once a day, only what they can finish eating within a few seconds.

Hi all I have attempted to keep sps in my tank for the past 7 months without success. Any help and advice from any of you is much appreciate. Below is some background info: Original Tank Setup - - Dimension - 4ft (L) x 1.5ft(W) x 2.5ft(H) - Age - approx 2 years - 2 x 120w razor maxpect - 2 x Tunze wavemakers - reef octopus calcium reactor - bubble magus skimmer (C9) - Nutrient export by refugium with chaetos - Livestocks :- 15 fishes, 5 clams, some snails, 3 urchins :- 1 toadstool leather :- 1 bubble coral :- 1 acan :- some mushrooms :- some zoas :- 1 baby hammer :- green star polyps :- skin polyps Additions/changes over the past 7 months: - added 1x wp40 and 1x rw15 - added 2 tubes t5 of ati blue plus - added phosban reactor to run rowaphos - changed saltmix brand from Blue Treasure to Red Sea Coral Pro - increased the height of maxpect to 10inches above water surface - changed fuge light from t5 tube to par38 red n blue - set fuge light on reverse photo period for 17hrs a day - started running carbon Now, my water parameters are: Salinity - 1.025 No3 - 2.5ppm Cal - 380ppm Mg - 1260ppm Kh - 8.3dKH PO4 - 0.00ppm Ph - 8.3 to 8.4 Tank condition now: - Fishes, lps, softies n clams are doing well in general - the few sps frags i have are not doing well. Some bleached, some turn brown, some have algae growing on them. - lots of green hair algae on rocks n parts of sps frags. Any advice and/or suggestions to help me keep sps successfully please? Thanks a lot!

Hmmm... i dun think i wanna take the risk lah. Anyway, my smallest fish are just 1 inch- a damsel n a sixline wrasse. Hahaha....

Aiyah, too bad then... at space's n budget's mercy... wait for me to upgrade house first... hahaha...

Oh, tat's true. But i got fishes! Can't keep cuttlefish with other fishes rite??? Definitely dun want my fishes to become cuttlefish live food! But if can keep together, it will be damn cool.

My parameters? Hmmm... Salinity - 1.025 No3 - 2.5ppm Po4 - 0.00ppm Calcium - 380ppm Kh - 8.3dKH Mg - 1260ppm But not so appropriate to talk abt my tank here right? Wait I kena complain! Let's go back to cuttlefish. Hehehe...

No lah, just doing things blindly all these while. Only recently then started trying to learn more... still got shiploads to learn.

Oh ok... thanks for the great info...

I already have a marine tank. Mainly lps, softies, fishes n clams. But recently trying out sps. Yet to have success though. Also considering species tank like cuttlefish, jellyfish or seahorse. But no space no budget for a second tank atm.

8 to 9 mths? Is that their regular lifespan? Sorry, i haven't been doing much research on them.

Hmm... dun really have a concrete planned setup yet. Still trying to learn more first. Cos i originally thought it is not possible to keep in home aquarium, so i never explore further. Until i chanced upon this thread. It rekindled my interest. Hopefully, I can start a cuttlefish tank soon.

So, wat type of live food to feed? I have always been intrigued by the beauty of cuttlefish. Didn't expect it is even possible to keep in home aquariums. Thought only in public ones. Pls, share more!

Is live food a must? Possible to train cuttlefish to feed on dried or frozen food?
