  1. Well not really a pair yet. I admit I only researched that they are hard to keep but didn't encounter anyone mentioning they should be kept single until I bought 2 back. Right now the bigger fella is chasing the smaller fella once in a while but no serious fight. I hope I won't have to separate them.

    They are super aggressive once introduced into our tank. I believe CW's territory is much larger than any typical tanks thus unless it is a proven pair, its hard to pair them in our tanks.

    Several attempts has been made to pair them but to no long term results, initially some feels that they are sexually dimorphic, i.e. male with golden head. I have tried and have failed. Without more proven results, I refrain from encouraging reefers to try to form pairs with CW.

    Let's not forget, CW was considered a "no no" fish to keep several years back and it was only the recent 5-8 years that we are having good results.

  2. so no problem if you clean once a month?

    mine 3-4 days already very black/brown, is it normal?

    3-4 days is good.

    I personally don't think cleaning once a month is good as I find that the build-up around the inner surface of the skimmer cup prevent effective skimming. That's why I don't connect my skimmer cup drains so that I will be force to service my skimmer cup twice a week.

  3. nsw is no no for me

    any method to make rodi water without rodi unit?

    iirc someone make rodi water using pump and di resin

    cheers

    Buy Distilled water loh.

    RO/DI or DI water need slow flow to a point of trickling in order to effectively filter tap water. So if you are doing major water change, you will need to prepare few days ahead.

    Some distilled water company are happy to sell on ad-hoc basis.

  4. thanks for your prompt reply

    my objective is to reduce accumulation of chloride, heavy metal, etc and also to replenish elements
    my main concern is will major water change bring more harm than good?
    i have bad experience in doing major water change, maybe due to using tap water
    cheers

    Can do major water change using NSW, there are still a few LFS providing such services.

  5. i was told its not advicable. i used to run 2 x 3.5 BMC (i terms of engineering design wise) if 1 fails i still have the other to last a little. Bt many was against it. so now change to 1 big skimmer. I notice the water tats collected in the cup is like expresso. but if i increase the flow it will be overflowing with foam like urs but the water is not so thick and greensig black instead of black. U wanna try to reduce the flow? I really also dunno wats the optimal foam setting. Some say its like 2 inch off the neck sum like say below the neck.....i dunno.

    Bro,

    You need to fine tune your skimmer in order to optimize the skimming.

    1. Adjust the air inlet to 1/2 position
    2. Adjust the outflow so that the bubbles in the skimmer chamber is at optimal height (different skimmer have different height)
    3. Fine-tune this height through air inlet, more air the height with increase slowly and reduce air will lower the area.

    I find most reefer will open air valve to the max and just tune skimmer using the outflow pipe. I used to do that too and find that this way of tuning crude and you cannot fine tune the skimmer effectively. Once you able to fine tune your skimmer, you should be able to get "cotton floss" skimmate with any decent needlewheel skimmer.

    HTH ;)

  6. I have tried several times running 2 skimmers and herewith are my opinions:

    • 2 skimmers similar performance skimmers will increase the effectiveness of pulling out DOC from your system.
    • If you have a better performance skimmer and a weaker skimmer, the effectively is not there and you will find the lower specs skimmer pulling out lesser gunk when the better skimmer is working.
    • Another advantage of 2 skimmer is that you can service individual skimmer on alternate days so as to ensure optimum skimming.

  7. Thanks for sharing, Gouldian. Sorry rhat I hijacked your post killerwhale. Coz my skim mate sometimes dark brown something light brown.. sometime a bit greenish (may be due to I scrap the rock).. so I wonder if my skimmer working well or not. Mine are not those fancy brand. Its AE from china.

    Several things affect skimmate consistency, quality, quantity and colours:

    1) Food and additives you feed

    2) Water level

    3) Feed pump - if it is a outsump skimmer

    4) Skimmer pump

    5) Livestocks

    6) Water parameters

    Assuming all water parameters are constant and stable and there are no livestock dying in your tank and you are feeding same food. I will check whether the skimmer is set-up to its optimal requirements. I will check on the bubble intensity, if bubbles intensity is not there, I will just change skimmer.

    HTH

  8. How do er know if the skimmer effective or not? Pls share..

    Its got to do with the fact that skimmer removes DOC (dissolved organic carbon). DOC are removes before there are broken down to Ammonia, Nitrite and Nitrate. Thus technically skimmer is effective in remove Nitrate.

    Protein skimmer mixed tank water with fine bubbles and DOC are adhered to the skimmer and therefore exported through the skimmer collection cup.

    There are also a host of products that claims to remove nitrate through binding and supported with skimming such as Lanthanum Chloride, AZNO3 etc.

  9. dono read on rc that should remove phosphate remiving media or it will reduce the efficiency of prodibio products.

    For me, I will use PO4 media aggressively to lower PO4 prior to reaching ULN.

    I feel if PO4 is still high when the tank reaches ULN, you will get cyano bloom. This is just my observations and also confirmed by a few overseas seniors I met recently.

  10. I have a clownfish and a carpet anemone for 1 month yet neither is attaching to the other... After putting in a rock attached with red algae, the clownfish started using it for its "home" (but this should be temporary since the red algae is presently depleting)... even the anemone is muching on some branches which fall in its way.... Therefore, my question is what are the possible alternative permanent homes for the clownfish rather than hoping for it to attach itself to the anemone, which may not happen according to some articles.

    Clownfishes don't need anemone especially in captivity. Mine pair are not hosted by any anemone and prefers one corner of my tank and even spawn on the glass surface there.

    Don't worry too much about it. ;)

  11. Hi,

    Is Zeolite suitable for marine tank? Read that besides its ammonia removing properties, will it crash a marine tank? Is it true that it too will soak up calcium minerals.

    Typically, Zeolite if soak in salt solution, this will "recharge" the media. Meaning to say, releasing absorbed toxic ammonia back into water. Kindly enlighten. Thks.

    Marine uses a different kind of zeolite stones that are suitable for our parameters. The first zeolite based product for Marine is Korellen Zucht Zeovit. However they are not easily available now in Singapore due to lack of distributor.

    If you are looking for Marine Zeolites in Singapore, you can try Fauna Marin Ultralith, they distributed by Aquafauna Supplies and also sold in Iwarna, MadPetz, Marine Life etc.
