[Neps]

Tank is 60x36x18 with caridina shrimp and otos. High tech, ~20-25ppm CO2 according to Hanna CO2 titration (ph drop 5.88 to 5.35 from Apera pH meter), with daily GLA PPS Pro ferts (0.8ml macro, 0.4ml micro). Growing monte carlo, glosso, buce, fissidens, rotala blood red, AR Mini. The carpet plants are struggling with browning and green fuzzy/stringy algae starting to take over. What setting should i start the Pro 60 at? It is hanging ~15cm above surface level.

- CO2 on at 10:30 am, lights ramp up at 12:00pm, photoperiod intensity at 12:30pm
- Ferts dose at 11:45 via pump
- CO2 off at 5:30pm, lights ramp down at 6:30pm, full dark at 7:00

Tank is 2 months old, planted for 3.5 weeks. Nitrates stay at 5, phosphates ~0.25-0.5. No silicates, RODI water used.

WRGB II Pro 60 is too strong for the 60x36x18cm tank.
You can hang the light at 30cm from water surface and reduce light intensity.

Photoperiod

Off: 6:00 PM
Sunrise/set: 30min
Light Intensity
RGB: 35–40%
White: 30–35%
Add 5% 1-2 weeks for growth
Algae
Ensure good flow over the carpet
Manual removal of algae
Add shrimps

I’m unable to increase the height to 30cm. At most maybe 17-20cm. What percentages should i follow at that height? Thank you for the reply!

Ill be moving the Pro to a new setup UNS 60U (60x36x36) similarly planted as in my original post. Should i start it at the same settings?

And i’ll be using a WRBG II Slim 60 on this UNS 60S instead. What settings should I run the Slim at for the 60S? Thank you!

WRGB II Pro 60 on a 60x36x36cm newly planted tank:
Still too strong.
Recommend start below 20%.

WRBG II Slim 60 on a 60x36x18cm tank:
Run the settings we talked before.
Add 5% each week for growth.
