Re: E Tenellus low watts to gal ratio

Hi Alfred,

My tank have about 2.8 watts/gal (140 watts/50 gals)  and my e.tenellus are about 1 feet high.  The leaves are thin as well.  If you want to grow shorter tenellus I think you need more than 3 watts/gal.

As for green water, I always add in more fast growing plants to get rid it.  Once cleared, I'll take out those plants.  This might takes about a week but always work for me for the outdoor tank.  My indoor tank never have an algae attack before.

Best Regards,
