I used this circuit to boost up the output of the arduino to 10V for the meanwell PWM dimming input.

LCD closeup.

From the top. 20x4 LCD display using serial connection to the arduino. The on/off button is to switched on/off the LCD backlight. The 2 buttons below is to manual on the blue lights or the white lights.

Fan is controlled using arduino to this solid state relay which can be triggered at 5V to 24V.

Internal wirings... very messy...

After a few weeks of coding, hardwiring, finally made my controller from scratch. My DIY controller is for 1) dimming the blues and the whites based on timinngs 2) moonlight based on days, towards the mid-month, would be the brightest 3) measure temperatures for my 2 LED heatsinks, if hit certain temperature that I think is too high, the LEDs intensity will be powered down less than 40% for abt 20 minutes to cool down. The overheat condition is to anticipate if the heatsink fans are not working, or ambient temperature is too high. 4)switching on/off the heatsink fans when the LED is siwtched on/off. 5)Added 2 buttons, white and blue, if pressed any one of them, let say blue button, will shut down the white LEDs and switch on the blues. Just for demo purposes.

still available...

I think its about time for me to spray with the coating to keep them nice and dry. So far no issues with my LED lights without the coating, probably because they are well sealed.

If leave more than a week, the dirt trap in the filter socks will cause the nitrate level to rise. Do change regularly. I have 4, and I rotate them every 2 to 3 weeks. At least 2 weeks to dry in the sun to let the chlorine bleach disappear.

Aiptasia.. ooo.. wow.. nice....

Upz..

no need chiller also can. Just put fan and the tank temp not exceeding more than 31degC

Spot on.. Now still break-in.. amount of bubbles awesome...

I'm selling this H&S skimmer due to upgrading. Skimmer & aquabee needlewheel pump are in good quality as always maintained. This skimmer is good up to 850 liters. More info on this skimmer Selling the whole set as you see in the pictures below. 1) H&S skimmer used as external or internal 2) Eheim feeder pump 3) Outlet tubes Selling the above between $350 to $380. I will not entertain lower than $350. New skimmer is more than $1k. After 4 days of skimming .... Consistant bubble size ... Quite a tall skimmer as compared to my son. Pls PM me for yuor interest. Self collect at Hougang.

Can try using seagrass filefish...

Bro, Any plans for auto dimming?

been using for a few months and my sump getting cleaner.

Just to check, for the driver ELN-60-48, how many 3W LED can you connect in series?

seagrass filefish....

Fragging? Did I hear fragging?

This would be my next DIY project.

Henry of Marine life is also selling. Good price as well.. Not sure if there is stock coz I saw 1 piece only.

nicely done!!
