DAY 18 - Last week updates
So on day 16 I freaked out a bit, but haven't seen any snails or more algae evolution since. The only thing I did was slightly overdosing Liquid Carbon in the last 2 days to put the algae in check.
Last week I changed the lights. According to PAR measurements, these new lights should
double light intensity when compared to my DIY LEDs. Hopefully this (in addition to CO2) will help Eleocharis to revive from the ashes.
It was week 2, so I've been doing:
- 50% water changes every other day
- lights on for about 6 hours (when it's sunny early in the morning, those rare days, I believe the plants get a bit less than 1 hour of direct sunlight from the window across the room)
- EI regime
- Macro nutrients 3x a week
- Micro & traces 2x a week
- Liquid Carbon every day.
Water chemistry is changing daily as follows:
- PH is changing between 8 and 8.5 (I want to bring it down to 7.5-8 range, hopefully adding CO2 will do it for me. Liquid Carbon affects PH, but not enough)
- Free Ammonia (the toxic one) ranges from 0.001 and 0.040 depending on the time of the day (plants are doing a great job).
- Nitrates are only tested 2x a week, but has been stable and under the danger zone.
These are the readings for last week:

I still have to find a way to keep temperatures stable when doing water changes (I am currently using 4x 2L bottles).
Yesterday
- Major water change
- Major trimming on the background plants
- Removed some water lettuce
- Removed some dead plants behind the statue
- replanted some bits of Eleocharis, removing the dead parts and replanting the green hairs in smaller chunks.
- Cleaned the Marimo Balls
- Cleaned and changed half of the cotton filter
- Cleaned sponge filter lightly
I also learned that having an internal filter, specially like the one I have (filter opening is bellow) is a pain... a lot of the filtered junk goes back into the water when I remove it. I probably have to start rotating it to the side whenever I do water changes or a clean-up.
Yesterday I was way to hungover to bother to take a pic...

I'll try to remember to take one today...
