CO2 setup

I've many people asking me how to set up a CO2 system so I'll just share my simple setup as a guide for you guys.

Setting up multiple tank from a single source of CO2 is proving to be a pain, I tried balancing with ordinary aerator splitter, metal lever and plastic screw type and it never work. Or I ended up with the hose exploding out from the splitter when the pressure got intensed. In the end I gave up and found a shop that sells regulator splitter head and this works like a charm. So dun waste your time doing what I did.

And I did not know that technology had advanced tremendously, there is now such thing as atomizer that produces extremely fine bubbles to maximize CO2 absorption. And you will need a bubble counter with the atomizer as you wont know how much CO2 is going into your tank.

You will have many choices to choose the size of your canister, usually from 0.5liter to 5 liter tank. I took the 3liter tank. Of how much CO2 you need to pump into the tank will depends on your tank size and how stagnant your water, the surface and quality of your bubbles. Quality of bubbles is how fine when they are released. I set mine to 5 seconds per bubble, meaning in 5 seconds I will release 1 bubble.

Set up :

1 - Pressurized CO2 Canister
2 - Regulator - get a good quality needle valve regulator, you'll have more precised control and I've heard of low quality regulator exploding which you wont want that from happening.
- Tri-head Regulator (if you intend to setup for multiple tank otherwise skip this
3 - Good quality hose.
4 - With or without check valve is good because we blast the CO2 24/7, so back pressured is not our problem.
5 - CO2 counter - you'll need this to estimate how much CO2 is going in, easier to control or you can just get a 2 in 1 diffuser with bubble counter.
6 - Diffuser

You're good to go with the above.

Tri-head Regulator, atomizer produces amazingly fine bubbles that is almost impossible to capture with my video.

Atomizer CO2 diffuser produce the most fine bubbles, I've to increased the bubbles otheriwse you cant see them.

Needle head regulator with back pressure

Tri-head Regulator, you will definitely need this for multiple setup, simple and perfecto.

The science behind Channa Marulioides colors and pattern

Channa Marulioides is the chameleon of the fish, they are the champion when comes to color changing abilities. In a split second they can change from greenish brown to yellow and to orange. They can change their eye color from black to bright red. Observe your Channa Marulioides and you can see they greet you with bright yellow colors doing the maru dance, they flashes their bands to the highest contrast. The body colors are intense and their eyes bright vampire red in colors. When they are tone down and just swim about their business you notice the color is dull when they are in mid water, and suddenly sinking to the bottom with bright orange (depending on the var and PH) they keep changing and flashing their bands and patterns. But the black and white flowers will remain so in whichever mood they display. Also take note that maru shows their best colors mostly at midnight. Each Channa Marulioides comes in its own unique pattern of bands and flowers, like a fingerprint, I beli

Tanning Marulioides

Another way you can bloom the flower of your marulioides is with the tanning technique. First lets understand a little bit about the flower. The flower is actually a dead pixel, marulioides are very unique fish, they possessed the ability to change color at will like a chameleon. But when the flower is formed that scale is spoiled and no longer changes color, it cannot get darker or lighter. As mentioned many times marulioides caught in river or big water always shows minimal flower, maru caught in dead water like peat swamp shows maximum flowers. Maru would need the color changing ability to survive, they can change color to hunt and to escape from predators. Meanwhile maru living in black dead water swamp do not need the color changing ability as much or maybe the low PH somehow destroy the color changing ability and the result will be plentiful of flowers or plenty of spoiled scale. I've done experiment on maru living in fast cycled tank and they lose the flowers or in ano

Marulioides Care Part 1 (Bunga)

I've been reluctant to write this but many had asked me to post how to take care of marulioides for maximum performance. The truth is you need to abused it, hence Marulioides care isn't exactly the correct terms to use. Channa Marulioides is found in most part of malaysia, lakes, pond, streams, rivers, but one thing most fisherman realized are those caught in swamp, I mean really dead stagnant peat swamp. Waters that are near black in color most time the fish had tremendous performance, beautiful colors and a lot of flowers. From this theory many tried replicating the conditions with low ph and so on. I've experiment many ways of keeping marulioides and I can concur to this, Low PH meaning Ph5 and below, I usually keeps mine ard PH4 or maybe lower, because my test kit can only measure till 4 and cant read anything lower. Low PH produce beautiful coloration. As for the bunga, yes everybody wants to know this, there is no tricks, just lots and lots of experiment. It i
