12L Nano Ryoboku Tank “Redwood” – Week 4

Almost all plants are doing well in my nano Ryoboku tank after four weeks. The Alternanthera melted but I had them replaced with a new pot.

The First Trim

So glad that for the first four weeks, almost all the plants have grown well in my nano Ryoboku tank. As you know, the tank was started using the Dry Start Method and if not done right, plants have the tendency to melt after flooding.

I think part of the success of this tank for the first few weeks was the amount of CO₂ that was injected to prevent melting. I made sure that the CO₂ drop checker was almost yellow in colour daily.

I have since toned down the CO₂ injection a bit and everything seems fine.

The Vesicularia dubyana ‘Christmas’ and Micranthemum ‘Monte Carlo’ plants had a headstart and the latter had become a thick carpet. As for the moss, it’s still spreading all over the wood.

I must say I’m surprised that the Heteranthera zosterifolia grew very fast and within three weeks, it has grown close to the waterline. The Heteranthera zosterifolia and Micranthemum ‘Monte Carlo’ was given the first trim.

Cycling And Growing

Whenever I start a new tank, I usually prepare a pack of biological filter media to mature about one month in advance before using it in a new tank. This helps the new tank cycle much faster than usual.

Usually, you’ll get brown algae (also known as diatoms) in a newly set up tank. There’s very little of it in this tank and I believe it has to do with the quick cycling of the tank using the mature biological filter media.

This also helps the plants adapt and grow better in a new environment. You may want to try this trick when you set up your new tank. You’ll just need another tank that has already mature and with a bit of space in the filter.

The One That Melted Badly

The only disappointment in this tank was the Alternanthera reineckii ‘Pink’ plants. When I bought them, they weren’t in the best condition but the roots and stems were still good.

I thought I’d give it a try but it all melted.

Nonetheless, another LFS just brought in a new batch of this plants and I promptly purchased a new pot. It was much fresh and healthier compared to the one I initially got.

This time I trimmed the best parts of the plants, planted them and it did well.

Using Less Light

Although I started with only six hours of photoperiod daily and did frequent water changes, some hair algae did appear in this tank. Could be cross contamination from my other tanks but I took action immediately.

I used a brush to remove as much of it as I can and syphoned them out.

I initially planned to have seven hours of photoperiod for this tank daily by the fourth week but for now, I’m leaving it at six hours until I’m sure the plants will outcompete the algae.

So far so good and I’ve not seen new strands of hair algae yet.

Waiting For Moss To Grow

Based on the experience with my nano Iwagumi tank, I think it’s best to put shrimps in this tank as soon as possible to prevent algae from growing out of control.

I’ll wait it out a bit until the moss has grown denser on the wood. I wouldn’t want the shrimps to be plucking the moss off the wood before it had the chance to establish itself.
