  6. 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.

  9. 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. Haha to be fair to ABA, their business model is fast in fast out, so can't help but have some casualties on the way. If you have a QT or just plain lucky, their fish prices are a fair bit cheaper than other places. So if you think about it, if you spend $100-200 on a simple QT, you'll get your money's worth if you shop at ABA. I know reefers who do QT, and they do have good experiences with ABA. As for SAS, try not to be too over confident also la, I personally know other reefers who got from there also experience mortality. Imo SAS IS "better", but as our Police like to say, "Low crime doesn't mean no crime". 1. Actually another way to reduce a little sound is to buy those food grade silicon mat, and put under the pump to further reduce sound which comes from vibration. You can buy on Lazada/Shopee etc, but make sure its food grade. Alternatively, you can buy at IKEA also, its not ex but just a hassle to go there I guess, slightly risky too with all the covid cases going on now. 2. Yea DC pumps are great for sound right? Btw, you could consider to use the "old" 1200 LPH pump for your chiller, and the new DC pump for main return + UV? Then maybe you can go one down from max. But in any case, running at max shouldn't be any problem imo, they're supposed to be designed for it! Just make sure the flow rate would let your chiller cool your tank efficiently. If you find that your chiller takes a long time to chill your tank, its generally either (1) undersized, (2) flow rate too fast or too slow.

  25. 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

  29. I was shared by a friend that his concern is K1 might generate lots of Nitrate. Actually, I have noticed that not many Reefer using K1 media at all for their reef tank. I am also not very sure whether K1 is good or not for a reef marine tank. But, I am very sure that K1 is very good for fresh water tank. After further consideration, I have decided to keep the K1 going and will monitor the possible / potential benefits for reef marine tank if it works. I am open for any opinions from reefers here in this forum to share their thoughts, opinion or experience in terms of K1 media for reef marine tank. There is no right or wrong answer, mainly just for sharing purposes

  30. Hi bro, don't worry about nitrite actually, nitrite is not toxic in marine tanks even at fairly high levels. But since you are monitoring nitrite already, then also since you are still cycling your tank, it is not a bad thing to see nitrite! That means that your cycle is moving on nicely. As for nitrate, it is also very good to see it now, as that means your tank is almost completed its cycle. Just let is be for a few more days and wait for ammonia to go to zero. Once Ammonia goes to zero, then your cycle is essentially complete. I would do the water change only once cycle is complete, maybe even up to 50% since your nitrates are fairly high. Once that's done then congratulations, you can add fish!

  32. 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. Hosting this chalice for a fellow reefer. Can see its covering a little more of the frag plug. Found a baby Banggai Cardinal yesterday morning. Scooped it out before it gets eaten by other big fishes. Feeding on baby brine shrimps The rest of the fries were released from the father's mouth tonight Manage to catch them out. Hope they survive.
