Hey bro
Thanks for your advise.

1. Should I get those with uv or without uv sterilizer?
2. No Co2
3. Will try to put some chlorine next time. Is it still recommended to use ro water or just normal tap water will do since we are going to chlorine anyway?

Any idea what are those brown deposits on top of my leaves?

Look much better now-

A few trick to make the tank clearer.
> water change 40% weekly
> cut away mature leave or decomposing leaves. The reach its peak form and slowly degrades over time and release organics into water
>brush the glass and also the drift wood with tooth brush.
> and of course, the Hang on filter got limited capacity, ensure you fill it with media ( and not only filter cloth)

Carpet plant- wont do well at low tech.
also you stemp plants- looks too long, cut the top half and plant it into the soil ba.
btw- can also consider putting seachem excel to boost the plant growth, beside macro and micro fertz.. have you started this topic as yet? lol

Hi.. so sorry I missed out your precious advise.. by the time I read this it is too late just to update my aquaplants most of them didn't survive, many of my fishes slowly gone up to heaven

last 2 months what I've done to my tank:
1. Did a full 100% clean up on my tank, removed some of my dead plants, removed quite a number of soil and sand for washing those fish waste but it never gets cleaned up to clear water level.. gave up washing those and put back into the aquarium

2. After putting in my new water, I notice my water is very murky. Probably I didn't put on my HOB filter as I was using it on my pale for my fishes when I perform the water change. After I install back the HOB filter, water slowly clear but still murky compared previously when no water change. I've added seachem stability also into the water but still can't get clear water as previously.

3. Bought some new plants and new fishes. Noticing my fishes slowly going to heaven one by one. Plants somehow some survived some are showing sign of rotting.

4. Suspecting it could be my water issue, so I bought a ph meter tester to test. My ph is recording 8.3, took a reading on my Coway water (as I use this water to do the water change) the reading is 8.1.. took another water test direct from my tap also showing a reading of 8.1 .. meter problem?

5. Did another round of water change last week, this time 20% water left inside tank without moving any sand or soil, result is still the same murky water compared to the first time. What could have went wrong? Is it because of the way I poured my water into the aquarium causing the fish waste to float more on the clear water?

I don't know where else can I find help but to get advise from experienced member here.
1. Adding another HOB filter so that it can help me to clean up my water?
2. Should I reset and redo my whole tank to make it alive again?
3. Should I start fresh just by putting soil and sand, just a bit of rocks and remove the wood as a start? As the aquashop owner previously explained to me before the wood can make the water turn yellow and raise the ph level..
4. I believe I have done many newbie mistakes.. What can I do again to enjoy back this passion given the chance to reset and learn? I think I was too naive back then venturing this hobby with the thought that I can have a ecosystem that can take care of itself with minimum water change..

ooooo thank you for the feedback. will have a look at your suggestion. ember tetra. hnghh.

yea about the RO. a hassle to always stock up. may op to normal tap water but need to buy something to remove chlorine (if any).

the lily pipe looks nice when new. super ugly when build up algae. hahaha. see how it goes.

just wondering if the DIY CO2 tank can be converted to a pressurised CO2 tank? my DIY CO2 using citric/soda turns out not viable for the long run as it depletes so quickly, the most I could get is almost a week for the 2littre tank. really troublesome to keep mixing every week.

if cannot, anyone knows any shop that sells or do CO2 refill in Ampang area?

thanks in advance.

How many bubble per second? I'm using one for my small tank setting 1 bubble per second can last for 1 month plus.

used to be 2bps but recently I cut it to 1 and still doesn't last long. now that you mentioned yours last longer I may have to check my line as I'm worried for leaks. I'm using the inline diffuser for 60p tank. how many gram citric/soda is your mix?

first glance, i say no.
sugar-yeast dont generate high pressure- so most likely the tank/regulator is of low pressure design ( unless u can confirm so)
be safe and get a proper CO2 tank ( those like UP Aqua or something) try look for second hand one. complete set around rm 200 or so....

pressurized gas can be a bomb. even using a legit one... i still beware when open the valve every time i change the cylinder ( normally open it with my hand extended behind cabinet door- so face not direct)

Ps- ys DIY CO2 need very rajin. and also need tune the flow when pressure run low? this cause flutuation on CO2 is a bad bad for your system .
