Main tank with overflow.....then the water goes into the sump..... then sump water send back to the main tank via return pump...and the cycle continues.... Picture of overflow (wait for a few minutes to see the water flows) Another place of overflow/sump info.. ...Sumps.....

non-expired ones works better...

Nice work bro..

Tie at both ends using cable tie and drop at fast moving water column in the sump.

Lots of food will simulate mating...

Wah... nice aiptasia... Anyways for good coraline growth, medium blue light and maintain at least 400ppm calcium.

Pending collection for skimmer and crystal pro.

Selling my H&S skimmer, good for 850liters tank, at $280. Plus free crystal pro DI. All the canisters are refillable type. Skimmer: Crystal Pro (Free): PM me. Self-collect at Hougang.

Can frag ...

I'm using Skimz Monzter SM202 Protein External Skimmer. Initially skeptical about the capacity that it could handle due to short height. But now after more than 3 months of using it, every week, skimmed about 3/4 full cup in black kopi tarik, so much more than my previous H&S A150. Really amazed by the amount of micro bubbles it produced, look like brown candy floss. My take for this skimmer, Pros : Small, well built, no noise, good support from AM, fantastic skimming, easy to tune & clean and value for money for the capacity. Cons : For mine, takes a long time to break-in (about 2-3 weeks), sometimes in-consistant bubble height, but once tune, can just left it there, and every week, just clean the cup.

Wah..

They are scavenger, just leave them alone. The more unwanted food in your tank the more worms.

Good to hear your birdnest is coloring up

Hairy crabs will eat your sps... Acro crab or bandit crab with the facemask, is ok...

Lugol's is iodine

Freaking good skimmer.. upz...

Good colours bro.....

wahhh.. so syiok...

Hope my thread would restart your DIYing again. Do let me know when you restarting.

I used the arduino software. FOC. Arduino download

Thanks bro. If got time, I will improve on my arduino sketch.

Not pro la... Not more than $120, it think. Costs for the items: the solid state relay at $20, LCD $23, arduino $17, LCD controller $10, clock $28, components like transistor, resistor, box abt $20++ or less. I would add more features such as internet, but too costly, at $70 I think.

Just for your info, I'm using clone arduino board and serial LCD controller at very good price at Ebay. Website : http://stores.ebay.com/AVRMEGASHOP
