Bubbles in substrate

[krabbie]

I noticed that there are some bubbles in the substrate, is this normal? I just added water into the tank last week ...

Probably just trapped air and isn't harmful.

But the bubbles appear only a few hours after the lights are switched on.

i knock the tank glass and all bubbles float up.....not the right way to do thou.

Its rather rare to see such bubles, may i know how you pour in the ADA soil when you started your tank setup?

I just poured the soil in as per normal. However, I was experimenting with growing HC emersed and hence the soil was without water for 2~3 months. BTW, I am using GEX, not ADA.

Just tried it and it doesn't work. The glass is 10mm thick. As long as it's not some bacteria or algae, I am fine with the bubbles.

should be fine, just that the soil has too much air in them, now forcing it's way out.

just normal, leave it for awhile and those air bubbles will diffused out.

Thanks. Shall monitor it for the next few weeks.

I am also using GEX and have similar experience. The bubbles will disappear in a couple of weeks

But one thing to watch out, make sure that the bubble isnt from a green substance in the soil, it could be BGA photosyn.
