Tank details:
Juwel Rio 180 (180 liters)
Filter Eheim Professionel 3e 1200 liters/h(4 months cycled)
1x 45W JBL Ultra Solar 4K neon (10 months old 8hrs/day)
1x 45W Dennerle Amazon Day 6500K Neon (10 months old 8hrs/day)
Fert soil by JBL covered by brownish ceramic quartz 5 to 15cm
Ruwal 20W UV lamp 24/7 (started when i introduced the fauna)
130 liters 100% osmotic water added with "Sera Mineral Salt" to get:
KH 4
CO2 fert to get:
PH 6,7
Temp constant 25°
Water tank has rougly 4 months of cycling atm
Fauna added 1 week ago: 15 Amano Shrimps, 15 Otocinclus Affinis, 6 Corydoras Panda*, 10 Paracheirodon Axelrodi*
*Fishes that got transfered from a MUCH smaller tank which i dismissed.
Issue: i made two attempts at growing Lilaeopsis Novae Zelandiae(LNP) with partial success.
1st attempt was with uncycled tank same water and lightining conditions(Started out with 6.5hrs and increasing up to 8 in 4 weeks): 1st week plants adapting, 2nd week plants sprouting really fast, 3rd week plants doubled or even tripled but sprouts were brownish rather than healthy green then green silk algae infested for some reason(uncycled tank?) so i removed the flora, turned off the lightining and left some leaf to rot for two months to give time to the filter to grow more bacteria.
2nd attempt 10 days ago changed 80% of the water with osmotic added with the same Sera salt, started out with 5hrs of light with 8hrs target in 4-5 weeks, planted again LNP and sprouts are getting brownish again.
I dont get what am I doing wrong, my hypotesis are several:
1) Bad light: the T5 tubes have worn off after 10 months and the light quality is insufficent.
DOUBT: manufacturers(both JBL and Dennerle) claim their tubes have long life: from 10K to 15K hrs and don't need to be replaced every year. Truth or lie?
2) Insufficent light: there are not enough watts to allow a sufficient growth.
DOUBT/DISPROVEN: while LNP prefers stronger lighining 1)if there wasn't enough light it wouldn't grow three times in just three weeks and 2) to disprove this point i built a plateau on the left (see photo) so that the LNP in that area is way closer to the tubes compensating for the lower lighitning
3)No liquid ferts: i haven't started fertilizing yet as i was waiting for plants to show signs of growth before starting Seachem basic protocol.
I've only been dosing some Flourish Excel as suggested by the retailer where i usually get aquarium stuff to boost plants intial growth and avoid algae infestation(? doubtfull but i didnt think trying would hurt)
Note: the water is crystal clear, the entire leaf(new sprouts) becomes brownish and it's not spot algae nor BB, the old leaves are healthy green and show no signs of decay or illness, the tank glasses do not show the typical brownish film that forms when lightining is bad somehow(i had this issue with Juwel T5 Highlite original tubes, after 10 days everything was brownish, glasses plants that were supposed to be fast growing would just turn brown and stop growing).
Conclusion: at this point i'm accepting any kind of hint to straighten up the situation before it gets too late, thankyou.
