I am using Seachem. Thinking to use API because cant find Seachem anti chlorine anywhere now.

Seachem anti- chlorine says it remove chlorimine and heavy metals too and ok to overdose.

Is API also good?
API is concentrated . Use sparringly per instructions.

Week 3 of Walstad Tank.

I did a water change and there was a rotten egg smell. This is a sign of hydrogen sulfide produced by the bacteria and is bad.

The plants on the right hand side are rotting and the roots are black. I guess that is the reason for the rotten egg smell.

I have to remove the plants that are dying and replace them with same type of plants as the left hand side, since those plants are doing well.

I have also started poking the gravel to release any bubbles trapped in the gravel, and did water changes everyday.

Hope the water will stabalise soon!

Week 2 of Walstad Tank. The duckweed population exploded and i had to remove some of them.

Spotted a few bladder snails but i will leave them alone as they will clear up the dying leaves.

Water is still brownish but is ok. The plants are growing well but slow.

Week 2


Week 1

Seachem is also concentrated. I am using like 1 drop for 2L of water.

Right now it seems Seachem anti chlorine is out of stock everywhere.

From my limited experiences, it seems algae attack those slow growing plants or plants not growing well. Sometimes it seems beyond my control to stop algae attack on those slow growing plants.

Ammonia from the bacteria in the soil and some snails

Once the roots are black, the plants can't be saved. This setup is pretty experimental with certain plant species more resilient and compatible with others (vs those which are not) so just persist and try different things. I am pretty keen to try this some time.

I'm surprised you have bubbles in the gravel since it looks pretty fine and compact. How much bubbles did you get? I should learn from this.

I was surprised by the bubbles too. I did poke the gravel quite a bit before adding the plants, but there were still quite a bit of bubbles when i remove the plants maybe i am using the wrong type of potting mix soil.
I am still fighting this battle as the bubbles stink!

If your fish is thousand dollars arowana then it is ok.

I know people who feed vitamins to worms which are then fed to their arowana.

Hello.. what kind of sand can i use for my corydoras?

Sent from null using GAGT

Ok since no one answered you, I helped you ask around. Some recommend pellet substrate such as soil from Tropica/Dennerle/ADA/G'ex and every other major manufacturer, especially if you wanted a planted tank. The pellets are fairly round and break down into fine sand, so should be fine for Corydoras. The internet and beyond does recommend play sand or pool filter sand. You can find play sand in 2-4 kg sizes from Lazada but pool filter sand seems more difficult to buy locally.

Ivenbetta recommends ANS Naturesand Red because it brings out the colouration of Corydoras. He brings in this and you can buy it off him. May need to pre-order as he runs out pretty fast.
You can also buy it from N30: https://www.n30.com.sg/soil/1166-ans...-sand-5kg.html
or East Ocean https://eastoceansg.com/products/ans...z-red-sand-5kg or https://aquatics.sg/collections/ans or https://simply-aquatics.com/products...31768642748490
Ivenbetta warns against using natural or white sand and the internet warns against using black sand - due to potential reduction in colour of Corydoras. Because sand is inert, it is not helpful for planted tanks. You need to lay the sand over soil substrate or have plants which are epiphytes tied onto rocks/driftwood or just have moss.

SUDO S-8815 Bottom Sand is a good choice. This is specific for Corydoras and the packaging reflects that. This is natural sand with no choice in colour though.
https://eastoceansg.com/collections/...ottom-sand-5kg
https://finsandpawssg.com/products/s...m-sand-1kg-5kg
https://green-chapter-shop.myshopify...ottom-sand-5kg
https://www.n30.com.sg/soil/807-sudo...-sand-5kg.html

If you want some other alternatives because ANS Naturesand and SUDO seem to be always out of stock, you can try JBL Sansibar but reports do suggest this feels rough https://eastoceansg.com/collections/...nsibar-red-5kg.

Hope these helps! Again my disclaimer is that I am no fishkeeping expert...

@Disturbed_Munky, this is the only video I can find about gaseous buildup in Walstadt setups. Maybe you can read the comments below the video. Not sure how useful this is for you.

Hahaha thanks this is interesting. Besides poking the soil, i also hit the table and the side of the tank and the bubbles are out. Thanks for sharing. Will try this too!
