5 months (Day 147)
Had a week long trip away and came back to a dense filamentous algae bloom, the long strands had formed a mat. Interestingly the plant growth was the most robust of all times with all the stems touching the surface which was probably the strongest growth that i have seen in a while. However the algae attacked the growing tips so I am assuming there continues to be instability with the algae winning.
It was so bad that i could not bring myself to take a picture of it!
Nitrates were stable at < 1 but > 0, and ammonia finally reaching 0 !! Maybe this is the timepoint when the tides turn and plants start dominating the algae.
Anyways did a massive manual removal which was painstaking but satisfying and had to do a huge trim of the R.blood red, R.tulunadensis and R.Hra. One of the difficulties that i have had with the R.Tulunadensis is that it branches profusely even without trimming and grows quite thick on the top that it shades the lower leaves very densely and the leaves start rotting easily. I am curious how people handle it when it is NOT in a dutch style tank where one would just discard the lower stems and replant that tops. I have reached out to @Dennis Wong but if others having it in a non-dutch style tank where you do not top off and replant with every trims let me know. I love this plant but might change it out for something else, if there is no other option other than replanting with every cycle.
I also did spot dosing with APT Fix prior to doing the regular water change at 80%. My plan is to to be quite aggressive with manual removal of algae and spot dose with APT fix. It does not seem to do much to the algae which is quite wide spread but worth a try atleast untill i finish the bottle.
Other points of note, my Blyxa is starting to flower (hard to see on the pic, better pics soon) which is quite cool. I have seen it in other's tanks many times but happy to see it in mine as well. The redness of the Blyxa makes me think that the PAR level is too high which might be the one of the driving factors of the algae but I don't want to alter the stability and want to see how things go for the next month or so and if still persistent algae without ammonia then will start dimming the lights.
The S.repens which was struggling with has taken off nicely, and a single L.Cardinalis mini survived and is thriving and I have divided it to see how it fills in some areas around the R.tulunadensis.
I don't seem to have an issue with surface scum at all, but with the aggressive algae removal and frequent trimming, I find the Oase skimmer at low flow to be a good device to catch the cut leaves.
