Plants Melting, Guppies Staying On The Top Of Water..

Seachem flourish is just a trace fert with a bit of nitrogen. You need to supply macro nutrient (N, P and K). You can add any fert ball/stick/tablet etc uder the gravel

Anyone knows the foreground plant name? haha

I also understand that CO2 will be loss very quickly if there are too much surface agitation and I'm pretty confuse to balance this thing...

That only creates current at that level of the tank in a single direction which can produce dead spots, so the upper regions are not getting enough current. Since you have dual inlets on the 2080, place each at either back end of the tank, and the output at the middle of the tank, with the blast directed towards your front glass from the back. Raise the output a little higher, say about 5 cm below the water level. This allows for some surface agitation, and reduces your CO2 loss. Placing it in the centre allows for water circulation to reach your intakes at either end of the tank. Alternatively, connect the output to a rainbar, and place it just a little below the water level for better circulation, or direct the rainbar as you wish. A little current directed at some plants seems to have good effects.

Observe the fish if their reaction changes. If there is sufficient dissolved oxygen, the guppies will not spend much time at the water surface, and they will be swimming around looking for food. You will not see your Oto or Corydoras rushing to the surface either.

Another thing you might want to consider is to aim for better diffusion of CO2 into the water. Some use external reactors, some use internal diffusers etc. If your CO2 is more efficiently dissolved in the water, the plants should grow better. You might want to consider DIY-ing one like Tom Barr's venturi reactor. I had one, well a version of it, for some time before I decom. my older setup and the plants were doing great.

Okay! thank you bro..looks like I have some modification I need to do later..

No preference, all brand are the same, you just need to know how much to dose.

Alright! :P

1. Can you take pictures of your CO2 tank setup? Anything from regulator or solenoid to the reactor (if any) to the dissolver.

2. Do you have young kids around which likes to toy around with regulator (if you have one)? The supply timing of your CO2 is also good info. E.g. 24/7

Frankly 1 bps will not cause much rush. In the case of a tank filled with CO2, you find the fish will be laying half dead close to water surface on leaves gasping air. Worst scenario that is.

3. I am more concern on under current, could you put your hand near the bottom and follow around gently if any detectable flow? Will it transport any fish that is in it's way all the way up too? Move your hand slowly, don't distrub the soil bed.
