Hi all
I have a problem as described in the subject line. It started slowly and changing the fert routine from Apt EI to Apt Zero has not helped. Neither has reducing the light intensity.
1. Size of tank = 64l (but 45 actually because of hardscape)
2. Age of the system approximately = 2 months
3. Tap water parameters =
Scottish Water data is as follows:
Calcium mg Ca/l Magnesium mg Mg/l Hardness as mg/l CaCO3 Clark degrees French degrees German degrees Hardness level
10.66 2.01 34.86 2.45 3.49 1.95 Soft
See the 3 screenshots for the other water parameters.
4. Filtration and Media = Fluval 407 using all the basket for biological filtration. Mix of 2 baskets Seachem matrix and one Biohome ultra mini. Seachem Purigen in the top basket.
5. Lighting and duration = Twinstar 600EA 7 hours on full
6. Substrate = Dennerle Scapers soil (18 litres because of the height)
7. Co2 dosing or Non-dosing = CO2 via injection (3 bps)
8. Drop Checker = no. I am using an Apera Instruments pH pen. Reads 7.8 beginning of lighting period and 6.9 at end. Can't get it lower.
9. Fertilizers used + Ratios = Apt Zero from the bottle. 1.5 ml per day.
10. Water change regime and composition = 80% water change at least once per week.
11. Plant list + Invitro/Emersed = all invitro originally except the fern. Glosso, Rotala Hra, Bacopa Caroliana, Pinnatifida, Pink Flamingo (barely hanging on), Rotala Wallichi
12. Inhabitants = 8 Harlequin Rasboras, 2 Ottos and added 8 amano's on Saturday last week (no effect yet).
13. Full tank shot and surface image = added
