Hi all,
I need a steer in the right direction please.
My tank is nearing 5 months old but has only been running with CO2 for around the past 3 months. I have been dealing with constant diatoms and so have been running it at relatively low light until I see those out (currently at 35% intensity).
My plants are showing signs of deficiency, most notable in the S Repens. This is confusing me as I am dosing 6mls of TNC Complete a day which I thought should be slightly excessive, especially when considering i don’t have a massive amount of fast growers and light is limited. Other symptoms are light surface scum and I’ve just started to notice a small amount of BBA on the root wood. The Salvinia seems to be doing ‘ok’ but not great.
Drop checker is dark green around 20 mins after lights on and I’m fairly confident the flow and distribution is good, almost excessive when the skimmer is on.
Do I really need to add more ferts, or is there something else at work here that I haven't considered?
1. Size of tank. 55ltrs
2. Filtration. Oase Biomaster Thermo 250. Ehiem skimmer as and when needed.
3. Lighting and duration. Twinstar 600E, 6hrs per day.
4. Substrate. Tropica aqua soil
5. Co2 dosing or Non-dosing. Dosing @2bps via inline diffuser
6. Fertilisers used + Ratios. TNC Complete 6mls per day via DD P1 doser, root tabs.
7. Water change regime. 75% every week
8. Anubias, various mosses, Rotala rotundifolia, bucephalandra, Monte Carlo, Rotala H’ra, S.repens and floating Salvinia.
9. Inhabitants. 12 ember tetras, 2 Guppies, 5 Amanos, 3 cherry shrimp, 4 otos.
