  8. Hi Darren, The ph graph looks like this after installing the additional FM100. So I would think another 0.05 increase in general? I have also made some other changes like increasing effluent and reducing my kalk dosage. So may not be entirely accurate representation of the effect. Oh. By the way, I also found out through a ph tank water airstone test, that my surface / tank aeration is too much compared to my ambient co2 levels in the room. Ie the co2 exchanges is happening faster than it can be removed sometimes. Made some changes on that too, ie increase aeration only during hours where ph of my tank is lower than an estimated ambient co2 levels. Sent from my iPhone using Tapatalk

  13. Kh Measurements - Alternative I end up getting a kH monitor. The device does not use reagents, does not produce waste liquid, does not require frequent calibrations. Too good to be true? In most cases, it would be. But thanks to good science and clever engineering, there is a solid alternative for kH monitoring. kH measurements (Part II) Other than titration method, there is another way for us to determine the carbonate hardness of the aquarium. For a carbonate buffer, such as seawater, the kH, CO2 concentration and pH are correlated. This means, if we know the pH of the aquarium, as well as the concentration of CO2 in the water, we can reliably calculate the kH of the water. You can take a glance at this article. Such measurements is not without its challenges. Firstly, in order for the kH calculations to be accutate, the pH measurements must be very accurate and precise. This requires properly calibrated pH probes which is accurate to 0.01 pH. Probes which can do this with consistency are generally very expensive. Not to mention frequent calibration is needed. Secondly, measuring of carbon dioxide concentration in water is expensive and inaccurate. Therefore if we want to measure the kH in this way, we have to solve two expensive problems: accurate measurement of absolute pH and CO2 concentration. Engineering to the Rescue Fortunately. There are ways to bypass these costly problems. If we can't measure the CO2 concentration in the water, can we adjust the sample to a known value? Turns out we can. By bubbling the sample water, we can make the CO2 level in the water to be the same as the air around it. Measuring CO2 concentration of air is easy and cheap. This, however, means we still need to have an extremely accurate pH probe, as well as a (cheap) meter to measure CO2 level. Again, engineering to the rescue. An Elegant Solution If we have two samples of water, at the same temperature, same CO2 concentration. Then the difference in kH is only affected by the difference of the pH of the liquids. And if we bubble two liquids with the same air. They will have the same CO2 concentration. If we use the same pH probe to measure the pH of both solutions, then the difference in pH can be measured very accuratly. [ for example, two liquids at pH of 8.01 and 8.03 respectively. The difference in pH is 0.02. If a pH probe is not well calibrated, it may read 7.99 and 8.01. The difference is still the same] This neat trick completely bypass the need to accurately measure any CO2 level, or having to measure the absolute pH. Oh wait. There is more icing on the cake. Since nothing (except air) is added into the sample, the water can be return unchanged to the aquarium. In addition, since it's not based on titration, the sample volume does not matter at all, which means there is no need to calibrate the sample pumps at all. All in all, in my opinion, too good but true. AquaWiz The device is AquaWiz. I have been using it for more than 2 month. It runs very well for me. I'll write more about it in the next post.

  14. Its not very clear in the full tank shot, but I do have some tiny cheap-ish ($10-$15) frags just to test water. But I did get a more expensive ($40) hammer LPS, so I get to see some "moving" corals at least. Probably the biggest challenge face keeping a tank in the office is the weekends, because I don't usually go unless I have some larger maintenance task I have to do like change water, which I do every 2 weeks, but long run I'm going to try to stretch it to once a month. But anyway I bought a cheap battery operated fish feeder (white colour!) to feed the fish over the weekends, so its all good. We also have cameras around the office, so can monitor no issue. The benefit of having your tank in the office is that I think most of us spend our waking hours in the office rather than in our homes actually (of course now covid is an exception), so get to enjoy the tank more. If your vendor/customer sends you a nasty email, then just look at the fish swimming then all will be well! Yea my wife is supportive for sure. Its just our home is not that big, and we have 2 young kids, so she wants our kids to have more space to move around. Plus young kids and wires don't go very well together, and we all know how much wires we have in and around our tanks!

  20. Same bro when i was cycling the tank. Every tank are different. I used microbacter quick cycling kit. Although it says 7 days, my tank took 21 days. Good to get ammonia to add once your tank are cycled. One it feeds the bacteria, secondly you would want to see that the ammonia drop to 0 within 24 hours than your tank is good to go Sent from Singapore Reef Club mobile app

  24. Assuming the white spots on your fish is "Ich".. 1) LFS usually use therapeutic copper in their tanks. It suppresses white spots so you may not see it in the tank, but usually does not not kill it totally. Even other reefer's tank may have itch, but because fish is healthy, can fight it off. 2) Yep if your fish is healthy and no stress, should be strong enough to fight it off. But your tank will forever have white spot parasite unless you keep your tank fallow for something like 9 weeks? 3) You can try polymedic as above. Most people says they are reefsafe, but I've read other forums not 100% success. Some use UV. Or both polymedic + UV together. Some people like to add "vitamins" to dip their food before feeding, eg. vitachem. Not sure if it really works, but at least shouldn't harm anything. Ich is not so scary, just try to keep fishes healthy. Velvet on the other hand..

  34. not sure about that. but I'm keeping torches, hammer, frogspawn with leather finger and toadstool with no issues. probably when you frag the leather just need to becareful, don't frag it in the tank as it will release toxin.

  35. Probably due to feeding, last time i keep feeding every 3 days and keep splitting. now i cut back to once per week and stop splitting. If u stop feeding and still keep splitting den probably stress or other underlying issues. Did u check ur phosphate? Reef roids tend to increase ur phosphates.

  41. Post hatch day 64 update Change to bigger box to allow for more growth, this isobox design quite good, with many holes for gas exchange and prevent detritus accumulation in the box. Got it from supreme. Prepping the food. Using TDO chromaboost, if u can buy the smallest size, but do take note smallest size mostly expired in LFS as nobody buys them. Do check the expiry date b4 purchase. Alternatively like me u can mesh it up to fine powder. Feeding time i use a coral feeder to feed so i can control the amount of food. “Pellet trained” hehe [emoji12] Size comparison Day 1, tiny winie fishies Day64, grown bigger liaoz, i only feed once a day sometime lazy, once every two days. [emoji23] Interesting and fun side to the hobby! More reefers shld try this out, they are easy to breed and care for, just need a little bit of TLC. Stay safe and happy reefing!

  48. Yellow filter photos. Some love it. Some hate it. It provides a better representation of colors of certain corals we see under blue light that is typically not possible to photograph. At times it over exaggerates the fluorescent colors of LPS. Coral fluorescence is determined by the glow (or scientifically called "expression") of green fluorescent like proteins (GFPs). Even though the name says Green Florescent Proteins, they come in various colors - from cyan to red & yellow. Quick google research suggests that fluorescent proteins (FPs) are reported to play an important role as photo-protectants and antioxidants in corals subjected to stressful temperature conditions. That is, to act as a screen to protect the algal symbionts (zooxanthellae). GFPs have peak emissions around the 485nm range. OK....anything more is beyond my level of understanding. Let's just enjoy some pictures instead. White light (no yellow filter) vs Blue light (with yellow filter) comparison. No color enhancement via photoshop.
