水草情迷

Greetings from Canada.

Here is my tank dimensions:

L: 30", D: 12.5", H: 18.5"
It is a 30 US gallon tank.

I am now using a 65 watt 6700K straight pin base compact flourescent lamp.
I have DIY Co2....

My questions are:

1) Should I buy one more set of the same 65W light for 種植陽?

Better ...... Your tank volumn is around 115L ... better have at least 115W light

2) What should be the pH value for 種植陽草?

Different plant may require different PH ... but in general , slightly acidic is better , let say around 5.5 - 7

Thanks.
