Walls Of Tank Options

[Puppies]

Hi All;
Extremely new to this forum... Didnt know there are so many experts here on goldfishes...
I have a 3 feet tank. read in previous posts that a sucker will not clean up your tank.
My walls of the tank is coated with a layer of slime, not algae... how do i go about removing that? it blurs the tank...

And, if i put stones/ pebbles (gravel) in the tank, how big the size of gravel I should have? I refer small stomes that can let the fish gup into their mouth, and spit out... is it advisable?.. as i read in previous threads that its not wise as it chokes and result in death of fish... But small pebbles at the base (abt half inch of height) looks good.

And how do we clean the poos trapped between the gravel? mine is a overhead filter...
Need advise,.. thanks in advance..>>>

Quite unlikely Genesis leh... I usually use one drop of Genesis per litre --> Kiasu. So far my fishes still ok.

When you see your fishes gasping for air, there's somethng quite wrong with the water. Did you have a pH crash? Got buffer or not?

Hi ;
According to advice;
1) I had a Anti chlorine and chromaine when i start off this hobby.
2) Bought the Round cylindrical ceramics and put in my OHF already.

Mext issue: pH!
Understand that pH had got nothing to do with the ammonia/ nitrire/ nitrate cycles (correct me if i am wrong)... but how do i know my pH is correct and stable? Can I just buy something to let me control the pH rather than getting a test kit?
