Water parameters: kH: 10 -11 pH: 8.5 Have not tested Ca level for 2 weeks, but dosing 2.5 mL spoonful "Seachem Ca reef advantage" every alternate day and alternating with 2.5mL spoonful Ca carbonate. Is this dosing ok? Other corals like hammer, jewel, sun, zooanthids & goniopora are doing ok.

Does any LFS sell Long-nosed Filefish? Thanks.

Does any LFS bring in Yellow Candy Hogfish?

Thanks Regal, Which Pasir Ris Farm are you referring to? Do you have any contact no for that farm so I can call & confirm? Rgds.

Hi Nicholas Yeo, Saw your comment on a nano reef to use a double air input skimmer for a 2 ft tank as I'm also using a similar Dynax skimmer. Can you elaborate more on what you meant by double air input? Does it meant to use another air stone for the same skimmer? or to look for another brand? Actually, I'm thinking of upgrading my skimmer but for 2ft tank, it's kinda hard to find a good yet small one.... Any idea from anyone? Thanks.

Hi, 2 weeks ago, I bought an alveopora which opened up in my tank but never as fully opened as it was in the LFS which I bought it. Few days ago, it stopped opening, I guess, it's gone. I supposed it's not an easy coral to maintain. Just sharing my experience. Anyone had great success with this coral? Felix

Besides CF, anywhere else selling small size Flame Angels. I did checked with CF, selling price >$60, that's expensive.

Hi, I'm looking for a small size Flame Angel, anyone knows which LFS has stock now or will be bringing in stock this week? Thanks.

Hi, I have a 2-ft reef tank and would like to hear from nano-reefers what's your usual Ca dosing practice (whether you do Ca test or not). For eg. do you use Seachem Reef Advantage Ca salt and add 1tsp (equiv. to 5ml spoonful) every alternate day and when you change say 10-15% tank water, how much Ca salt do you add? (This is what I intend to do). I had problem with using X-glare Ca test kit and suspect results are not true to the actual Ca level in the tank so I want to hear from you guys your Ca dosing practice is like. Please share your experience. FYI, I have jewel coral, sun coral, daisy coral, goniopora, hammerhead, zooanthids & frogspawn and 4 fanworms. Looking forward to hear from you. Rgds. Felix

Thanks MadMac My water is always clear. Will read the article that in the link. Anyone with a 2-ft reef tank, can share how often you add Seachem Reef Advantage Ca salt to your tank (for eg. your response could read 1 tsp (5mL spoonful) on alternate days. For 15% water change, add 2 tsp Ca salt) based on your Ca test? Thanks. Felix

Hi, I'm selling my Gold-bellied Damsel and Blue-lined Damsel. Interested parties, please pm me for further details on collection & pricing. Rgds.

Hi MadMac, The link on "Correcting Ca and Alk Problems" had some problem. Cannot open webpage. Thanks Minsmarine for offering advice.

Hi, in response to questions asked above, 1. I'm using Tropic Marine Salt Mix. 2. There's no precipitation at all coz if I do add carbonate (I will add only the next day after adding Ca.) 3. When I say I remove 30% of water, I actually meant removing a normal pail of tank water. 4. For evaporation, I do top up every night to the right level. 5. I did not intend to scrimp on test kits but was introduced to X-Glare by the LFS. Experience comes with learning and advice from fellow reefers. Will try better test kits. 6. I believe Ca & Carbonate present in the tank water exists in the free form (not bound or else water will be cloudy), hence can be used by corals but may not be detected by test kit. That's just my assumption so Ca test must be performed prior to adding carbonate (if there is a need to add carbonate). 7. I use Seachem Reef Advantage Calcium which already contains Mg & strontium in the right porportion, would the Mg level still be low and do I need to add Mg separately? BTW, my tank is 2-ft, guess that's about 75 to 80L. Rgds. Felix

Any LFS carrying pink clove polyps? Thanks.

Ok & thanks, I'll test the Mg level. By the way, any recommendation on a reliable & accurate brand of Mg test kit to look for? And which LFS carries Salifert Ca test kit? Does Aquastar carries it?B] I more or less also suspected that the carbonate level in the water also affected the Ca reading but did not know how it affected it. Thanks for the explanation. I read somewhere that corals need both Ca & carbonate so sometimes I add carbonate when the dKh drops to 9 just to bring it to 11 or 12. Is that really necessary? Worse still, this is affecting my Ca reading and I can't seem to find a trend for the Ca reading after 2 months of weekly testing?? Now I agree that marine fishkeeping is a bottomless pit, keep spending & spending.. Thanks, you guys & gals are really helpful.

Thanks to everyone for chipping in with the response. My rocks do have some red coralline algae. I dont' test the Mg level so I don’t have the results. However, the pH is always constant (between 8 – 8.5) & the dkH is also quite constant (between 9 – 12). It’s just that the Ca is never constant. With such low Ca level, I’ve to keep adding Ca powder. What’s the conclusion based on all these responses? Get another test kit? Anyone using X-Glare Ca test kit having the same problem as me? Those with 2-ft tank (approx 70 – 80L), please share with me your Ca salt dosing frequency and your Ca readings so at least I can have some reference. Thanks again. Felix

Thanks for the suggestion. Did the credit card scratch your glass?

Hi, SRC members, My 2-ft tank has brown and some green algae growing on the sandbed and the side glass. I clean the glass with a yellow sponge approx. once a week. However, some of the algae are hard to come off and I don't wish to scratch the glass. Can someone suggest how you "scrape" off the stubborn algae growing on the side of the glass tank without scratching the glass? Can an algae scraper do a good job? I have a snail but it's not clearing the algae fast enough (those on the glass wall). I will get more snails soon but still need advice on removing algae on glass wall. Thanks. Felix

Hi Reef Club Members, Need your help on this calcium issue. I have a 2 ft tank with some damsels & corals like sun coral, jewel coral, frogspawn, hammerheads, octopus coral & zooanthids + a starfish. After changing 30% water, the Ca level would drop from 460 mg to 210 mg as measured using X-Glare Ca test kit. Then I would four 5ml spoonful of Seachem Ca Reef Advantage powder (dissolved in water) over the course of 2 days to bring back the Ca to at least 420 mg. Also added two 5 mL spoonful of carbonate. The puzzling thing is 2 days later the Ca level has dropped to 150 mg. Then I added four 5mL spoonful of Ca again over the course of 2 days but 1 week later, the Ca level is still at 180mg. 1. Is Ca absorbed at such a high rate just over a few days? 2. What is the normal Ca dosing like for a 2 ft tank? Is 5 ml spoonful twice a week good enough as instructed on the bottle of the Seachem product? 3. Or is it because X-Glare Ca test kit does not provide accurate end point reading? 4. What Ca test kit would give the clearest end point and accurate reading? Thanks and I hope someone could enlighten me on this issue. Felix

Thanks, should be this one.

Hi, Can someone advise what is the name of the LFS that is at Jalan Kayu including address details & contact details. Reply from anyone is appreciated. Thanks. Felix

Hi RAV, Any picture to show? Does it move around alot? Felix

Hi, Where is Blk-D Ah Beng coz I'm interested in the soft corals. Please provide full address & contact no, & directions to go there. Thanks.

Hi, Do you have pictures of your Fire Clowns & Fox face? Cannot find pixes of these fishes in the web. Are they reef-safe? Does Fire Clowns attack Common Clowns? Rgds. Felix

Hi, Pardon my ignorance. I have a 2-ft tank and uses only 1 Arcadine Marine White Light and a Blue Light. I think it's T8. That's what the LFs says. I'm keeping jewel coral, frogspawn, hammerhead, octopus coral & zooanthids. They seems ok. Also supplement these corals daily with phytoplankton. Is the lighting enough? Should I have one more additional T5? but there's only 2 standard light tube holders, how do I get an additional light tube holder? Thanks. Felix
