But for 35 quid you could buy 2 years worth of excel in a tank that size lol. Pearlings not important anyway mate, they'll still load your water with oxygen.
The diffuser on the fluval mini kit isn't that mini though...
I got it from my local Swallow Aquatics, it had a Betta in which quickly went in a larger tank, the lighting and filter I built, guides are in my sig.
Cheers mate, I hate those snails, had two when I started out and they slaughtered my tank with eggs that I couldn't get off. Ruined my first nano. :'(
nice pic of the snail...i had one in an old tank and agree, the eggs are a complete mare to get off. DIY yeast would work on a tank this size.
