  1. Any1 know where can get this item?

    For those u stay in newer flat, in the service yard,the power point for washing machine has a cover for it.. I looking for that

    Sim Lim Tower or some hardware shops but do note there are not cheap. Alternative is to get those food container from Daiso and DIY. ;)

  2. Nutrients Overload! Diatoms on the sandbed and tank walls, hair algae growing over all tank walls and some of the rocks, bubble algae starting to appear on the rocks. This must've been due to my feeding of 1 cube of mysis every alternate day!

    Tested the parameters yesterday night and they are as follows:

    Salinity: 1.022

    Ammonia: 0ppm

    Nitrite: 0ppm

    Nitrate: 5ppm

    pH: 8.5

    kH: 7.0 dkH

    Calcium: 360ppm

    Magnesium: 1180ppm

    I haven't gotten a phospate test kit as yet, however, I'm thinking that its the frozen food which is causing the phospate levels to spike thus causing the algae to grow. I'm wondering if there is a saturation point for the algae growth, by reducing my feedings at this point of time since I don't have much fish that requires heavy feedings.

    The level of nitrogenous waste product are being kept in controlled at this point of time too and I don't feel the need to worry about these 3 parameters. However, its the big 3 that I'm currently worried about.

    IMO, its the SG that is causing the lower Ca and Mg levels. I've been trying to raise the SG by changing water every week and replacing it with a saltwater with SG 1.024. However, this is going to be slow as I'm only changing about 5% of the water each time round. I'm skeptical about directly adding saltmix to the sump right now as it will cause some fluctuations which will affect the organisms. Maybe someone can chime in with regards to this issue.

    I'm also thinking of dripping kalk once I have adjusted to the ideal SG and Ca levels so as to maintain. Currently, I only have a favia and hammer coral and I don't think they are huge consumers of the Ca. But I'm thinking of going to automatic dosing in the near future, maybe after I see the effects of kalk,

    Another way to increase SG slowly with minimal stress to LS is through evaporation. This can be donw through your weekly water change regime.

    1) If for example your weekly water change is "Y" litre of water

    2) Prepare "Y" x 1.1 litre of water (10% more)

    3) Siphon out "Y" litre of water and replace with Y1.1

    4) Test SG at the end of the week and adjust with necessary

    With this, as the water evaporate the salt remains and will increase your SG slowly and "naturally" as LS are used to slight change of SG during drought seasons.

  3. Cavitation....a new term to me!

    Thanks Gouldian for the advice! Really increasing my knowledge on pipings and pumps after I got into this hobby!

    Hehe, cavitation is commonly used in marine engineering since propellers generate bubbles.

    A improperly sited pump will also create cavitation, I have recently mounted a small pump with the impeller faced down instead of horizontal and with that I get lots of micro-bubbles even though the pump in fully submerged.

  4. Unless you have a huge tank will lots of space for the dragonets to established their own territories, if not it is not advisable. I have a pair of S. moyeri and when I tried to add the ruby red, they would chase and bite the new comer till death. :(

  5. Simple guideline for dwarf angel sexing is always get pair with a distinct size difference and you should have a higher chance. Understand that male potter tends to have more blues while female more brown.

    My Fluval is run out sump thus sometimes the pump vibration may brush against surface of the sump causing a humming sound. Other than that, its perfect. The air lock issues are actually caused by the piping works and mine was resolved on the spot and no issue so far despite me turning off the pump for a long time.

    In my personal experience, all high flow pumps will have a potential of air-lock if not installed properly. As mentioned by DA, the contributing factors is on the piping works.

    I have ran Iwaki MX70 to MD55, to Ocean Runner 6500 to Eheim 1262 to Waveline 10k to Diablo 10.5k for my return. Same set up but different pumps and all of them, needs minor twitching to get the pump running optimal.

    Beside air-lock another challenge is micro bubbles due to cavitation. This, I feel is also another problem that is often misdiagnosed.

  6. When I touch it, my fingers turned brown, the container has some brown stains on the sides which my iPhone cam couldn't capture. So does that conclude my rowas normal?

    Can not conclude la, we are just layman trying to verify using our layman way. Best is to check with FnM whom you have bought or with Reef Dept who is the agent. ;)

  7. If you touch the media, do you get rusty stain on your fingers? From my experience, the Rowaphos should be wet and will stain when touch, that's why when use will Rowa filter sock, the sock will turn brown after using.

    Also, are you taking the photo with the Rowphos in the container? So far, the sides of my Rowaphos container is never so clean. You may want to verify with Reef Depot.

  8. thanks man, i've gotten a biomature bacteria and i've been adding 5ml everyday. hopefully by one week i'll be able to add fishes in :)

    The only way to determine when your cycle ends is to test for the ANN spikes and recessions. By estimating a time frame for cycle to complete is not advisable.

  9. Is it okay if i just leave them in the tank? Will it cause any harm to fishes or corals in the future?

    This is very common in new tank, for the next stage, you will liking encounter hair algae, diatom etc. Some reefers prefer to leave them alone but for me, I prefer to brush them and let my filtration system export out.

    Those that advocate leaving them alone feels that brushing them may lead to spreading to other parts of the tank.

    I have tried different ways and find that brushing them away works better for me.

    It's your call. ;)

  10. Tank is still in the process of cycling with daily dosage of Continuum Bacter Gen- M(Nitryfing bacteria) and Bacter Gen- M(Denitrifying bacteria). In addition, fixed up my VEGA today and absolutely loving the effect.

    Tidy up the cable and it will be super nice liao. :thumbsup:
