Folks, could you sanity check this for me please:
I plan to do a low light low maintenance C02 Asian theme tank. Plants will be mosses, ferns, various crypts, Blyxa, C. Helfrei and Danoi.
Tank is 90cm * 45cm * either 50, 55 or 60cm high - I've yet to decide. So we are looking at either 200 or 240 litres (or, disturbingly, 180L or 220L once you take into account the thickness of the glass ). It will be a rimless, braceless "pool" aquarium and it will be drilled with bulkheads for filter in and out. Heater will be a Hydror exteranal heater, CO2 will be via an Aquamas external reactor. So there will be no visible tubes into the tank at all.
Question 1:
Will 2*39W tubes = 78W T5 HO with reflectors be enough? The first gives around 1.25 - 1.5WPG but this is T5 so I _think_ according to Colley's multiplier (http://www.ukaps.org/forum/viewtopic.php?t=537&start=16) this should be ok. Anyone with experience?
Question 2:
According to the 10*golden rule I need around 2000/LpH flow. Can I get away with a single Tetratec EX 1200? If not can you connect multiple filters in parallel to one inflow/outflow and combine the flow rates or do I need to invest in a big expensive Eheim 3e?
Obviously answers to both questions effect the budget significantly...
