Bilti`s 2.5G DIY AIO Pico

Recommended Posts

I had a very old wish to make a small pico reef for my office so I said that now is the time. As the ordinary glass is not the best decision for such a tank I have decided to go with the ultra clear type : Diamant de Saint Gobain.


Below you can compare the quality, in the left is the ordinary one.




After ordering the glass is time to use the silicon and make the tank. Due to it miniature size the quality of the seal is very important and we have to use some tape.

the tank is 26x23x16 cm and 5 are reserved for the filtration located in the back. In inch this is coresponding to 10x9x6 so a total volume arround 2.6 gallons.


The back will have a DIY background in order to hide the pump and the filtration.

Looking very good. It's worth noting though that the smaller the tank the less important starfire glass is, because smaller tanks use thinner glass. The effect becomes more pronounced as the the glass gets thicker.

Thanks Astking. The regular glass has a very bad quality here and this was the main reason to go for ultraclear.


Back to my pico now is time for hood preparation!


For this I use a DIY one made out of komatex and cover with black tape (is a kind of tape which is use to cover large area and to give a wood look. I don't know the word in English).


First I want to cut the hole for the LED`s. The main purpose is to have the heatsink out of the hood. This is to keep the water cool.

LED, pump and electrical connection:


Base on my experience I have choose the 10watt led model so 2x10000K and 2x actinic blue under driven at 2,5watt. In total of 10watt.

The algae is from the old setup. I hope to solve it in time with a blue leg hermit. Can I use other method?
