I have a Fluval Vicenza 260l tank currently lit by 2 x 39 W T5's with reflectors.
are my calculations correct and is my lighting ok as I am suffering some ongoing issues and trying to rule out certain things like flow/circulation, c02 distribution and lighting.
260 l = 67.6 US Gallons
2x39w = 78 watts
78 / 67.6 = 1.15 wpg? am I doing this right?
I have presurised c02 running from a 2kg FE, JBL adjustable pressure reg and solenoid running 3bar pressure through an easy aqua super atomiser, co2 is running from 2pm til 9.30pm with lights on at 5pm and off at 11pm (6 hr photoperiod) drop checker is yellow at lights on and at max for fish/shrimps.
Filter is fluval 305 which isn't great for flow/distribution but is doing great job filterwise, due to the possible low flow/distribution I have added 2 x powerheads at each end of the tank to aid this, c02 bubbles can be seen all over tank with good sway/movement to flora.
Dosing ei solution 5 days and carry out 50% water changes at least weekly, but have been doing 2 x weekly 50% changes for past 3 weeks, am suffering with some bba and staghorn on bogwood and some plants, i've also been adding double dose of Neutro c02 liquid c02 for the past 3 weeks, it's difficult to spot dose this to the hardscape as it's quite large and in order to reduce the water level to gain access to the bogwood I would need to remove approx 190 lites of water.
I'd like to know if my lighting is too high as I can't increase my bubble count of co2 it's running so fast at the moment i can't count it. Some of my plants have just started to melt, losing leaves, becoming translucent an have holes in them, if my lighting is too high I can obviously reduce the co2 to try and balance things better if I had lower wattage lights, i've tried to read everything I can especially from Clive and I know it points to c02 uptake? but i'm unsure now of what to tweak to try and make things for the better.
Tubes i'm using are 2 x 850ml Sylvania 39W T5, tank is 260 litres and 4 foot
any direction would be greatly appreciated
oh, and i've now been test kit free for 2 weeks and feeling great!
