What will be your fertilization regime?
sloppy and casual.
i add liquid fertilizers (liquid preparations of KNO3, MgSO4, KH2PO4 & CSM+B) directly to the surface of the planter gravel. this ensures that the ferts get to the roots of the emersed plants and also limits extra nutrients in the water. one could fertilize a setup like this using EI or other rigorous regime, but i count it as a plus that i don't have to do so many large water changes or watch the calendar so closely. i want this to be a low maintenance display. in this case i think that i only need to dose 1X per week.
i will have a moderate fish load and the immersed plants will get much of what they need from them. i have a similar smaller setup that has been going for a while with happy plants and the only extra thing that i ever add to that is CSM+B mix from time to time.
Can we get a full plant list of what you have in there to get an idea of what can be grown in this type of setup?
mostly there are a lot of crypts. here is a partial list:
- Cryptocoryne cordata
- C. balansae
- C. ciliata
- C. lutea
- C. wendtii (3 different cultivars)
- Lagenandra sp.
- ..and a few more[/I]
on the Epi-Trellis Rafts i have Anubias barteri
sp. and Bolbitis heudelotti
in the underwater portion i am going to plant crypts belonging to some of the above species and a few more. i need to look for some shorter plants for that area.
How are you controlling humidity and what humidity target level are you seeking?
i will maintain the tank nearly covered with a glass canopy. the humidity will remain at >90%. i will have to adjust this to some degree. most of the crypts will grow best with very high humidity, but there are some that actually grow with more attractive appearances in lower humidity.
