Thanks Sub Zero! Learned a new word :-) Hi JMW, flow rate not affected at all.

The tank update Sent from Singapore Reef Club mobile app

We know algae scrubber works. Grow some algae in the sump and it competes for nutrients. The sump’s algae grows but your tank is less “algaefied”. But with Nano tanks our choices are limited due to lack of space. You can buy the Innovative Marine (IM) magnet LED light, cut a hole in the backing (not the glass haha) and shine the light into the back IOS to grow algae. Clever solution. What if there is a simpler and cheaper way? When I got the IM 10g tank I bought the grill guard. It is to prevent small fishes swimming into the back (forgot what is the technical name IOS or something.) You get two grill guards in a package. So I stuffed some chaeto into the grill guard and clipped it on the tank. Algae started to grow because some parts of the led lights reached the chaeto. And every 2 weeks just clear the bad algae. Some chaeto will die off bec lack of light. If someone come up with a transparent guard you can convert the back wall into an algae attractant factory. Low cost. No need to buy extra light. No need to slice the backing. But in terms of aesthetics maybe the IOS Light is better. Just sharing. Sent from Singapore Reef Club mobile app

My 10g nano tank has the usual additives - magnesium, coral Food, vitamins... and the corals are well fed (I think). 3 days ago, out of curiosity, I decided to chop up a frozen oyster (from NTUC Finest, note it is not live oyster) and feed 1/3 of it to the corals. They just “bloomed”. Maybe there is iodine and other additional nutrients. Just kidding. Maybe it is just a coincidence. No direct causation effect. But nice to see the corals blooming. Like S$6 for a pack of frozen oysters that can last months. And don’t overfeed as usual. Just sharing this observation and happy reefing! Sent from Singapore Reef Club mobile app

Thank you! Once I finished my Seneye cartridges this is exactly what I have been looking for. Sent from Singapore Reef Club mobile app

I think he is using this : https://www.isocket3g.com/en/ From temp monitoring I think isocket is superior to Seneye. I use Seneye and you need to plug into a pc or buy their web server. Plus the monthly update of the cartridge like sensor “plate”. However I think isocket requires a SIM card to work. Everyone is waiting for an affordable all in one monitoring sys. Google and you see many Kickstarter projects trying to accomplish this. So many times the chiller pump jammed and the tank started dying. Sent from Singapore Reef Club mobile app

Dear Reefers, After nearly 3 years keeping a saltwater reef tank, I realized the best lessons have been given by all the seniors here. There is really no magic. No “secret additive” nor method. I made several horrendous and expensive mistakes because I refused to listen. So here are my own 10 lessons: 1. If you want corals, get a chiller. Or pick very hardy corals. 2. This is I think a rule I kept procrastinating to obey. USE RODI WATER. Full stop. I tried all kinds of work around. Nope. Just get the cheapest RODI water treatment system, add salt and that solves so many of your problems like algae, poor coral growth etc etc. To me, this is the most important lesson. 3. Change 10-20% of your Aquarium water even if the water looks “clean”. No point doing all the nitrate tests. Just change it dutifully. I am in the water treatment business and thought I can beat the system by using various methods to avoid water change. I am wrong. Just do it. This is the second most important lesson. 4. Don’t overstock. Resist the temptation to buy “a few” fishes. Come on one extra Fish won’t crash the tank. It will. 5. Feed very little. Alternate day feeding. Don’t worry they won’t starve to death. 6. If you keep corals, get a good light. 7. Read and research. 8. Listen to the seniors in this forum who have done it before. 9. Don’t buy anemone unless you have shielded your wave maker. Blender kill has caused my tank to crash a few times. 10. Figure a way out to maintain the tank with the least effort so you won’t hate it. Had I stuck to the above rules I think I could have saved myself lots of blind alleys, frustration and money. You will note that I am saying nothing new. That’s precisely the lessons I learned. Last rule - have fun. Happy Reefing!! And I would love to take this opportunity to thank all the Bros here for the advice so freely given over the years. Sent from Singapore Reef Club mobile app

It is a second hand chiller. And I realize to have nice coral - RODI water, 15%-20% change water a week. That’s about it. Sent from Singapore Reef Club mobile app

Mine is between 27.5 to 28. They are doing fine. Plate coral. Sent from Singapore Reef Club mobile app

Apologies. I thought your tank is cycled. It is not. Sent from Singapore Reef Club mobile app

It is your water change that causes the ammonia to reach zero. Please read this site and many info on cycling tank Sent from Singapore Reef Club mobile app

Wait hang on Sent from Singapore Reef Club mobile app

What are you waiting for? Lol. But add one fish first to test. How did you get ammonia to zero in 8 days? Did I miss something. Sent from Singapore Reef Club mobile app

Just get it or any RODI. Worth it. Sent from Singapore Reef Club mobile app

Reverse Osmosis water I should have known better. Ok I am in the water treatment business which explains why this is embarrassing lol. I have often withheld the purchase of a RO unit bec a) takes up space b ) come on! I am in the water biz why buy a machine from another co (mine is more industrial/commercial) c) I like the idea of going to a LFS using buy saltwater as an excuse. Don't we all! And yes I have to combat red, green "algae", bacteria, non performing corals etc. I just got the small RO from FM. Now the tank is incredibly clean and you can feel the fishes and corals are happier. What took me so long despite all the seasoned reefers here recommending RO/DI water? There is a bit of water wastage but I can repurpose the "waste" water for my plants, freshwater tank and other household chores. So if you are a newbie reefer like me, go for RODI. It is not compulsory but it makes your life so much easier. That should be the first few things I got. Sent from Singapore Reef Club mobile app

Understood the science and of course you are right and a great posting! I think it is nearly impossible to make a tank free of itch cryptocaryon. 1. The idea is to tip the balance. Ultimately the fish must be healthy enough to fight off the itch. So adding the UV light "may" (big may) reduce the itch infestation. In my tank (lol, sample of one, hardly scientific), after introducing the UV in the IOS, my blue and yellow tangs are no longer bothered by itch. Occasionally, you see them scratching their bodies (symptoms of itch) but after a couple of days, they stop doing that. Could it be the UV light help? Perhaps. 2. In my tank filter I also introduced nanosilver ceramic beads (my own company product) to kill bacteria (nanosilver kills bacteria we use it for disaster relief emergency water treatment .. yes we know nanosilver may be bad to the human body after prolonged usage but it is for emergency relief when no power is available and we have a patent so that there is no leakage of silver into the water.) again could it be the silver nano at work? We don't know. And if there are testers out there it will be cool. Using it for aquarium is obviously not our business but hmmmm if it works will be great. As usual, we try and experiment that's why science is fun. Cheers!!! Sent from Singapore Reef Club mobile app

Fastest solution is to get UV Sent from Singapore Reef Club mobile app

Hi Sir there are so many factors and reasons. As reefers we try our best but sometimes bad things happen to good tanks. But these are some of the things we can do to minimize sudden death syndrome: 1. Did you slow drip when you introduce the new fish? It may not get used to your new water parameters. Some fish are hardy and some are not. 2. Whitespot. Add a UV light. It solved all my white spot issues. I also added my own co antibacterial nanosilver beads just in case. 3. Temperature. Do you have a chiller? I am sure other reefers have other pointers. Good luck sir. Sent from Singapore Reef Club mobile app

Wow thanks! My uncle will be very relieved to hear that. Sent from Singapore Reef Club mobile app

It is quite small. I am not a Tang Police but sooner or later you need to upgrade to a larger tank. My uncle has a huge tank so no problem. But it prefers larger tanks. Sent from Singapore Reef Club mobile app

I am posting this for my uncle who is a reefer too. He found this purple stuff on his corals and it does not look like algae as it got "holes". Can help ID please? Thank you!! Apologies if this is something common. Should we scrap it off? Sent from Singapore Reef Club mobile app

Hi (assuming you are asking me.. not very used to the forum interface), it is jebao AK-60. It is a clone of the Kessil blue. But I recalled nearly 1/3 cheaper or even more. Sent from Singapore Reef Club mobile app

Sorry for the late reply. I use the auto wave function and when the water level starts behaving like an up and down movement I clicked Set. It is zero for pulse power(?) - the last knob. Power of the wave is set to lowest setting. Sent from Singapore Reef Club mobile app
