I've had my 105 gal set up for 9 months. Fish are happy; no losses at all (Rainbows, rasboras, GBRs, cories, serpae tetras, and 3 pearl gouramis).
I continue to struggle with the plants, though. Not growing very fast and seem to be overtaken by algae. Anubias and java ferns have spotty black algae. Also I think I have some beard algae but I'm not sure if it might be another type. Filamentous type algae on the stem plants.
I have anubias attached to driftwood--the ones in full light are full of algae. java fern, swords (doing terrible), Jungle val, and wisteria (doing terrible), and Elodea (doing better than most).
Things I'm considering--advice please!
Using RO water for changes--invest in an RO unit?
Adjust pH down to raise CO2 (if I'm understanding chart correctly?)
Change light bulbs?
This setup was done for me by a store which I have now realized is not experienced with planted tanks. The choices weren't my own, so any adjustments or suggestions would not be taken personally
Water plant CO2 system--with bubble counter--currently two bubbles/sec
48Lx18Dx22H display tank
Durso pipe from overflow
Current tank values
(using a chart with pH and KH, my CO2 is low at only 2-3ppm?)
Dallas TX tap water: pH 8.1, KH=3, GH=7, NH3 1ppm, water utility uses chloramine
Why is the tap water so alkaline but not very hard?
I use Prime conditioner. I do a 20-40% change every 1-2 weeks.
4 T5 bulbs:
Wave point tropical wave
Giesemann lagoon blue
I bought and used PPS pro
First at rec dosage and then at half and now I'm not using it
I have seen some algae improvement
(The PPS pro recommendations: I think I qualify as medium light at my wpg (2.1), 8-10 hours/day
CO2 a bubble/second per 25 gal so 4 bubbles/sec?
Target 15ppm CO2
1mL of each solution/10 gal
So: 10 mL of each solution each day)
I have never managed to get my CO2 concentration up!
I have been using Flourish Excel for a couple of months, one capful daily which is a half rec'd dose, and I think it has improved algae (but I also stopped ferts and lowered lights).
I currently run the lights 8 hours (I have been reducing that too)
I am very frustrated! I am hoping that those who know more can tell me where to start adjusting equipment, water, whatever!
