YAY CO2 party!

I made my own CO2 set. It wasn’t the first time; I tried several times already but the result was always negative. I recently found out that I need use a specific kind of plastic tube (one that is pretty hard and thick) to make my CO2 set work. An other mistake was that I used water bottles,.. apparently the (plastic) bottles for water (and milk) is just too thin; you really have to use a coca cola, fanta, sprite bottle to make this work!

to make everything easier (because you will need to fill your CO2 bottle every week) I bought some bottle caps from ebay and a CO2 glass diffuser. Once you have everything, the set up is very easy and quick. There are dozens of bio-CO2 recipes online,.. they all differ a little bit. Some use a lot of sugar other prefer jelly and boiling water… the most important part is to have your whole et up leak free, onze you have that, you can easily switch to a better recipe etc. make sure you don’t use too much CO2 though. Im using quite much because there are still no fish in the tank, and Im having problems with algae. once the plants are thriving I will slowly lower the CO2 amount.

I made a little video of my CO2 set :)

update 28-02-2015

Here’s an update of all of my tanks (counting: 4 now..I think Im addicted; I really need to stop now). The first one, a +-10 liter planted tank, is currently on my little ikea table surrounded with chamber plants. I had to buy a clip-on lamp though, but Im happy I did it because the plants are growing well. I re-used one of the HOB filters and the shrimp heather (Im planning on selling the other one since I will not use it anymore). The NO2 and NO3 levels are still wayyy too high, but Im patient. I still have to wait at least 2 weeks.

oh and as future inhabitants: I really like yellow shrimps and maybe one or two snails. the tank’s function is to grow little plants though.. because you always need more plants!

I have good news for the second tank! I saw the baby shrimp again! yay, he survived (I could not take any good pictures of him, he’s soooo tiny). Im planning on buying new red cherries soon because 3 females died (found the problem but I still need to go to the store).  I also added a little bit more sand, to make the background a bit higher, the tank looks bigger now and there’s more light for the plants (see before and after pics). The anubia’s are growing very well, I have two new leaves already!


before: messy with plants growing everywhere.


after: more space and light enters!


The betta tank is also doing really well! The plants are growing fast and all inhabitants are are less shy (they often come closer to my finger now). Apple is a very friendly betta, he really doesn’t care about the buzzing kubotai’s (I love them, they are very active and so nice to look at) the scissortail rasboras are also less shy, and getting bigger everyday. their tails are bright yellow and black now (used to be light grey when they were stressed).


The last tank (the biggest) had some problems.. the tank is still empty, because of the high NO3 and NO2 levels. I tried to add as much as possible plants, to make the process quicker. I recently found out that my tap water wasn’t ideal for the tank (PH = HIGH, KH = super LOW, GH too, NO3 = high) so I started using rainwater now, It’s better but the KH is still very low and KH is okay’ish.. so yes, I have a slight green and brown algae problem, but Im planning on making a good bio-CO2 set to lower the PH and give the plants a boost.


let’s get it started!

Remember this dirty mess? brown – green sand (that used to be white), lots of rotting plants, no water flow lots of green and brown algae.. and dying fish. Yep this was the 180 liter rio of my brother. We decided to sell this tank because he didn’t want to take care of it anymore (let us call it the ‘depression period’), and I did not have enough time (and money) to restart the whole thing..

for 2 months it was for sale. The best offer we received, was 120 euros. I wasn’t convinced. I just didn’t want to let it go. we had so much fun making this tank, choosing the fish.. patiently waiting for everything to grow.. it was a real memory tank and even for that amount of money I did not want to get rid of it…

6 months later, we still have the tank, unused. I still do not have a lot of time but I have more money, I can plan my free time (and work time) better and my brother started working and his depression is getting better now. He starts the re-enjoy things he used to do, like reading, listening to music and.. taking care of his tank. We decided to restart the whole thing. I bought tons of sand (now its more beige than white, more natural, prettier), lava rocks (they are beautiful!) and a new pump (the Eheim, see previous post).

So this is how the tank looks like now (the spiderwood is floating again so well have to be patient, but it will be placed on the far right in the back). I used several product of HS aqua (water starters mostly) and ferro and profito for the plants. Im planning to make a DIY CO2 set too.


all pictures are taken with my cellphone, sorry for the bad quality..


the left side, and the intake of the filter. the moss had just been adjusted to the stone.


the far left, with moss, one little anubia (more will come, I love anubia’s) and the outtake of the filter.


my little mosswall.. It doesn’t look good but this is just an experiment. well see ;)

and the hero of the story: the filter (sorry for the surrounding mess, I still need to clean that up)
