Hi Bro,
The amount is meant to replace evaporated water.
About a quarter of the bottle per week, in other words, 1 bottle last you 4 weeks.
Depends on whether u want to top up daily or weekly then.
Top up during lights off as it will make your tank cloudy for a while..
I had it for almost 3 yrs previously.
Rocks are stacked up against the back wall and its ok.
But I do have black oyama pasted at the outside of the back tank wall.
Anyone knows what kind of bannerfish are those at Ah Beng in the blue tub?
Heniochus diphreutes or Heniochus acuminatus?
Was there for almost 15mins, looks like Heniochus acuminatus..
Hoping the get the former..
To add on to the stock list, a few goby and pistol shrimps pairs in the bags..
