I add lens to those leds above where the screen go below the water level And the algae growth increase See attached photo below Algae growth after led changes to those with 40 Deg lens

Good.You have a supporter now. Next time easier to buy LS or fishes

I want item 4 .Can collect tomorrow

I want item 3

Shoiuld be 24 vdc and best 2.5 A

Max 6

Meaning those China,Taiwan,Hong Kong,Malaysia ,Italy,etc led has only 50 % of SSC,Cree,etc, efficiency. Meaning to produce the same amount of light intensity you need to use 2 time the current. Meaning more heat will be generate . Hence life is also half

How about me? Mine is a cube 7

I have visit Sim Lim Tower very often. I don't think you can get a 15 to 20 A , 12vdc for cheap.

For the chiller project I need 12 vdc. The cheapest DC power supply today is the PC power supply. Most fan running 12 or 5 vdc.

Shot in RAW give you plenty of ground for editing

There are different methods to cool down the water. Iceprobe use a ceramic probe to transfer the coolness to the tank water. We can use the water block method. Meaning we sit the water block on the peltier(s) The peltier will cool the water block. We run water into the water block and the water will be cool down. But very hard to find water block on 2nd hand market. And they do not sell alone in Singapore market. Maybe there are bros here can help to machine a water block. Any one can help?

Bro, Your chiller need to cleanup .The radiator look clog with dust

I have that before.I bought for S$1. Good to use initially. But when rust cannot work liao

Still studying which method to use. This is something very new to me and not many good references to refer

Also remember to get a SG meter. You need NH3,NO2 and NO3 and PH for cycling. Other can get later when the cycle is over

Thank You for your support,Bro comycus

Yes.That is what I am DIYing.Hope it can work

Find a PC power supply to run the peltier. First short the green and adjacent black wire in the big molex. More detail in another DIY project.

Found this heat sink and this peltier in Sim Lim Square/Tower respectively Mounted the peltier on the heat sink by 3M thermo tape

Anyone can help to ID this I find it growing on one of the LR together with zoo and blasto. What is theis plant? Is it harmful?

This is a 5v and 12 v DC power supply setup using PC power supply.

I cut the green,black ,yellow and red cables and connect them to a terminal block for easier access Black is common Red is 5V Yellow is 12 v

For the benefit of those DIYers who do not know how to make a PC power supply unit run when it is not connected in the computer. To make a PC supply unit run as stand alone Find this biggest molex Short the green and alternate black cable
