Well....
End of day three of the black out today. Just done a 50% water change and to be fair things are looking much better already.
I think I was being a bit harsh previously saying that, " I tried starting back with EI for a week and only made it worse" It was nothing to do with the EI, because I left all the NPK and Trace elements in the tank during the blackout and the Reineckii Mini has gone a dark deep red and looking gorgeous, whereas before it was looking pale pink and sort of greeny yellow, so EI has had a positive effect.
If I am being completely honest I also realised that I had miscalculated the mix for the NPK, I was working off the old measurements from my old Trigon 190 and forgot that the mixture was based on a 20 gallon tank. So when I calculated for 300 litres I tripled the mix forgetting that the previous amounts were already doubled. Now that's a b"£$$ up if ever I saw one.
During the blackout I also left the CO2 on almost permanently, at one stage the AquaMedic digital ph reader was showing 5.85 ph and I was a bit concerned that some of the fish may have karked it. But they all seemed fine today. Fed them a bit
I think I have identified what caused it. Now that the days are longer and brighter a fair bit of sunlight gets into the room, so this combined with eight hours of 4 x 54 watt T5 tubes was far too much light I reckon. So I have rotated the reflectors so that they are almost pointing upwards, switched one light off permanently and reduced the time for the remaining light until the plants have recovered.
The black out is back on at the moment and I have re-dosed the EI NPK and will continue for all of next week to monitor how it goes. But I am feeling optimistic, especially after reading Vaskez's post about his
slight algae problem when he came back off holiday.
😉
Will post some photos next week sometime when hopefully things are back to normal.
Cheers,
Steve.
