Thank you, may I know where can I get a sand shifter starfish?

Anywhere i can buy Nassarius snails since the sand bed is getting some brown algae? Thanks

Test again with Salifert Nitrate tester, it is between 2 and 5. Low range is 25-50 which is between 2.5 and 5.0. Skimmer is 5 times+ of water volume, maybe that contribute. I guess Mitchell is correct since no dead organism from live rock, not much source of ammonia. Will slow down a bit and keep an eye on it. Thanks Bros.

Tested Nitrite is zero (Salifert). Cannot get Ammonia Tester.

Thank you for the information. Have put 1 liter seachem matrix for cultivating anaerobic bacteria, plan to put another 2 liters for it since my tank doesn't have a lot of space for live rocks.

Sorry another question, Does N-Cycle up to NO3 generation or denitrification?

Thank you, will keep an eye on it and test ammonia and NO2, will get some mixed salt water ready to change.

Haven't bought tester for ammonia and nitrite. Only bought NO3, Calc, Mg, PO4 tester. Will buy ammonia and nitrite tester after work today. Coral and fishes in tank looks ok till today. Doesn't look like there is any sign of ammonia / nitrite.

Dear Bros, Seeking advice about N-Cycle, i just start a new tank and it has been running for 7 days. I am not sure whether n-cycle staring or not. Day 1 setup, everything's fine, tank set at 25 degree, skimmer on, refugium on 7x24, with some Algae in the refugium Day 2, the tank start to appear some brown algae but not bloom Day 3, added 5 small (about 1/2 ~ 1 inch) clown fish and a Ricordea Yuma Day 4, added 3 small zoa frag Day 5, added Seachem matrix 1 liter, denitrate 1 liter, and active carbon Day 6, set timer for refugium light to be switch on from 19:00 to 08:00, chiller set to 26 degree Day 7 which is today. Test NO3 every day. Day 1 is 0, Day 2 is 12.5 and Days 3 onward till today is between 12.5 to 25. Fishes and coral all looks good. brown algae start to grow on artificial live rock Tank size: 30" x 18" x 18", main tank about 150 liter water, refugium about 30 liter. Over-sized skimmer: for 1000 liter (plan to do a sps tank) Just 2 small piece live rock in refugium, and using artificial live rock on main tank. Caribsea Livesand I am wondering whether the n-cycle finished yet. Should i change some water now?

Excellent! Thank you for sharing

Finally leave to Iwarna Victor help to sort it out:p Looking forward to see my new tank

Amazing!!

Thanks, RomeoJuliet. I think i need to look for some smaller equipment for my sump then i could redesign it. Looking to change skimmer to Deltec MC 500 any recommendation on return pump which is smaller ?

Thank you RomeoJuliet. Have extend it a little bit which is the limit on the tank size, unless i use one pump to chiller then back to main tank, which could give a little bit more space.

Hi, I am new to this forum. This is my first time to have a sump which i am not sure whether the sump design is correct. Only got limited space therefore the size of sump would be 22" x 14" x 16". Skimmer: deltec sc 1350 internal protein skimmer Pump: Eheim Universal Pump 1250 x 2 Chiller: Not confirmed yet. Main tank: 30" x 18" x 18" Wavemaker: Tunze Nano Wavebox 6206 Light: not confirmed yet Draft some picture to show the concept, Please help to comment and give advise. Thank you.
