Yep Dr Tim Hovanec sure does know his bacteria. I think over time many companies have got a little better at this. Brightwell certainly has improved and is a good source too. But I trust Dr Tim's products. I use the one and only as well as the eco balance and also have the waste away product. If you watch his MACNA presentation (via youtube) on how to use bacteria to cycle a tank, he gives some great tips on how to get through a good cycle. Well worth the time to watch.

Just sharing my tank after upgraded to RedSea tank 7 or 8 months later..... See how jialat the poison I have now...... This is how I "diving" daily.... Hi @CarnivorousGhecko, I do 10% water change weekly. For ammonia Nh4 and nitrite NO2, I do not bother them once my tank is cycled because always get 0. Once have enough filter media / live rock, and the number of fish is fixed, I always get 0 for both of them. Sometime I feed a bit heavier also to make my tank's bacteria can handle slightly heavier nutrient load. Due to having mixed reef, my NO3 and PO4 are high. I am using Nitraguard Titanium to reduce my NO3 and Rowaphos to reduce PO4. I am start using them when I had the 2 feet tank. My NO3 level is the most red color measured by API NO3 test kit during that time and PO4 detected low with API PO4 test kit. After using them, I am managed to reduce the NO3 to yellow color (API NO3 test kit ) and very light green color (API PO4 test kit). Think that the NO3 and PO4 are very low already?? Actually not! After switching to Salifert, it detected NO3 is around 25 to 50 ppm and Po4 around 0.5 to 0.8ppm. Just some personal advise, if you would like to get more accurate result, spent few more dollar to get Salifert test kit. Last time I choose test kit by looking on their $, but after trying salifert and compare the result with ICP test, the Salifert test kit result are more accurate to ICP test (by comparing Cal and Mg reading) But now my fishes getting bigger, I cannot further reduce my NO3 and PO4 by the 2 product. The NO3 always stay at 25ppm and PO4 at 0.5ppm. There is one time I change all the NO3 and PO4 after water change, and thinking to chase the number, end up it stressed my coral. I lost few coral and injured my chalices. So now I try not the renew them after wc, and slowly top up / renew them every 2/3 days. Eg: top up 20g every 2 days until the number I want. Anyway, just sharing there is a rowa calculator available: http://rowaphos-calculator.com/ , you can use it to calculate how much rowa you need for your tank. But try start with 50% of the recommendation. *Anyway, the above are just my personal experience and opinion. Every tank is unique due to the way you feed / the way of maintenance / the livestock or equipment you have. There are plenty of way for nutrient export, and it might not the most effective one, but it works to reduce my tank NO3 and PO4 to the level I mentioned.

Amid circuit breaker period and also Labour day, on a rainy cold nite, it’s so boring..... so fortunate still can admire my tank....lol Just taken this night shot with my iPhone with yellow filter.

Quick iphone pics from today Side view Following up on the Apex temperature probe. This is what the final implementation looks like. 3D printed tube mount (left side for sump level float switch). Right side to hold the Apex temperature probe. Using the dremel to cut & later grind off the plastic pipe to ensure a perpendicular cut Installed in sump It works This resolves the issue where temperature probe is out of water when excessive water is removed (eg. water removed when fragging or acclimatizing fish). And yet ensures the tip part is not under water when the return pump is off.

To share, print bracket to hold shield to block light from tank when view from a distance away.

Good sharing on the need to be careful in reefing. Deserve to win something.

A daytime shot from last month after the torches were sold. Pardon the milky water as I took this picture right after adding purple up. [emoji1] The tank will look very different if I could get rid of all corals on the bottom to review a clean white sand bed. It looks more calming with an exposed sand bed.

A random tank shot I took on my phone back in Feb, just before lights off and when most of the torches were still around. Sent from Singapore Reef Club mobile app

As the government CB Stay At Home period has been extended to 01 th June. This contest will also extend to the end of the CB period as well . More time and chances to stand to win some prizes !! #StayHomeStatSafe #reefersunited

Last time I drilled my bubble magus skimmer for an overflow. Have to be very slow and careful not to crack the plastic. But it might spoil the sleek look of ur skimmer

Any suggestion if it's a octo classic series? Vertical type. I've been thinking of drilling from the side but kinda not as efficient as the one you did.

Like what clement said. Best is drill a hole. I've consulted a few tank maker and most said overflow box might become blocked etc and caused very messy problems. And what's more, drilling hole practically is also much cheaper then those overflow box. Also depends on what type of tank is it.

Very good info bro. Read through the whole post of your finger, rashes, hospitalise... Felt the dilemma you were. Hope you finger is getting better now. Anw I still couldn't get it, alot of fish keeper has wound and touches the water. But this is the first time I heard about such incident. Could it be maybe some coral or tank additives that penerate into the wound thus into the vessel Glad everything turns out fine!!

Beautiful coral tank . Coral in good looking shape!

Hi Guys and lady I have a 2.5ft tank, having so much problem to put my dosing pump. As you can see my sump tank no much space left Ended up I drill two hole at my wall and install my coral box dosing pump. I felt good and save a lot of my space. I am sure you guys thinking what I am thinking. Will the light affect the liquid right beside ? I put a black cover to block the light and heat. I am thinking to put a wallpaper on TOP of my dosing pump like what S3 are selling. Hope my DIY can give you guys and lady more ideas. Happy reefing !

Used aquapharm before and quite effective. Off uv and lower the salinity to around 1.019 within 2 days Dose accordingly to the treatment label and you should see improvement.

Haha spot on. Even has a grouper

Used ro before. But changed to tap water with dechlorine. Works great and save ro time

Nice write up and collection for aspiring reefers like myself ! [emoji1303] Sent from Singapore Reef Club mobile app
