Here we have a planted 20gallon high which is the first planted tank i have done and its doing well. The tank is stocked with the following fish
1.1 apisto viejita
1.1 bolivian rams
5 neon tetra
12 endlers
1 bristlenose pleco
Lol your a real clown, as u can see that's a secondary and my kids make filters all the time so here is your logic in that statement? No life at all its really sad.
i showed them how to make a bottle filter one time and now they can make a filter out of anything lol. they work really well and if your starting a new tank u can take one out of your old tank to cycle the new one.
