Hi all,
I have just had another very close look at my algae. What I thought was a type of GSA appears to be a diatom.
On rocks it is easily wiped off using just my hands but on leaves it is a bit more stubborn, but I can remove it, whereas previously I could not budge it.
I did reduce my lighting back down to one T5 45w tube at 6hrs per day, although it probably has not been reduced for long enough to have an affect.
I switched to a 2,000lph APS filter two weeks ago and I am now using a 65mm Bazooka for CO2 diffusion and ph is dropping by about .6 /.7 of ph .
Now as this is a repetitive pattern, is it worthwhile to do a full blackout for 3/4days (indeed does a blackout work) or a soft (just lights switched off) for may be 5 days. Followed by a large WC.
If it does work is this likely to mean having to change my lights or just working with one tube for a couple of months?
