gravel cleaning

Hi! I bought this fish tank about 3 months ago (38 litre). I have had fish in there for roughly 2 months as I ensured I cycled it well beforehand. The past month I’ve had this algae looking stuff on the driftwood and also the Java fern (but mainly the driftwood). My gravel is also quite brown...

Hey guys, I've just bought a 100L/ 20 gallon tank and I'm waiting to pick it up at the moment. Very excited! It comes with 2 internal filters (both Aquael 700) and a heater which is great. I was looking into keeping some honey gouramis, platies, neon tetras and maybe some leopard cory's? Nice...

When doing a water change I use the vacuum thingy and go over the gravel.  However, the gravel is tiny and I lose loads of gravel.  Is there a way to stop that?   :good:
