Hi everyone,
I am still struggling to get photosynthesis to happen in my tank! Can anybody maybe pick up on what I have wrong or maybe doing wrong?
My corner tank is 180litres and about 65cm deep, I now have a good flow rate with my spray bar and 2 Koralias mounted in each front corner pointing down and towards the middle – my plants and grass seem to be swaying nicely. My tank is not that heavily planted, it has quite a bit of redmoor wood with weeping moss attached (vesicularia ferriei) most of the bottom covered with grass (echinodorus tenellus) and a nice big narrow leaf java fern with some anubias dotted about – I don’t have any tall stem plants now that maybe hindering flow etc.
I have 3 T5’s (24watts each) on for 7 hours a day and I am running injected CO2 at a rate of 1-2 bubbles a second, so that my drop checker is a nice lime green. My PH is around 7 and at the end of my CO2 period it drops to around PH6.4. My co2 comes on one hour before the lights and goes off one hour before lights out. CO2 is through the up atomizer and when I watch the CO2 mist looks like it is reaching all of the tank areas nicely. I am also dosing 7-8ml of TPN+ daily with a 30% weekly water change.
My thought is do I have my lighting high enough for this deep tank, I have thought of adding a fourth T5 light, this would then take it to 2.4 watts of light per gallon as opposed to the 1.8 watts it has now, do you need a certain amount of light for photosynthesis to start happening or am I jumping on the wrong track?
Can anyone help? I feel like I am on the verge of cracking this somewhat frustrating corner tank!
