Hi all im new to planted tanks so go easy on me lol. I have 6ft x 2ft x 15inch tank and in the process of setting up,the equipment ive got and planning to use are: Dennerle full c02 injection with night time shut off running of a FE bottle of 13kg. Dennerle under substrate heater of 75 watts. Dennerle Duomat and ph controller. Dennerle coc400 Bio station. 2 fluval 405's external filters. 2 80 watt t5 aqua medic plant grow,a 54 watt t5 aqua medic plant grow and a 54 watt juwel high lite day tubes. All the above lights have reflectors. Tropica substrate,ada nile sand and fine quartz gravel. TGM petrifed wood/stone as decoration. My plan is to plant 3/4 of the left hand side of the tank fading to a sandy section on the right. The plants i want to use are Vallis,Echinodorus tenellus,Dwarf crypts. A couple of questions really: Would there be enough co2 going through the Bio Station or could i split the feed through another diffuser?? Would i need to increase the lights,filteration,flow?? Your thoughts please, Many thanks in advance. Stu. :? :? :?
