Hi Geoff,
Thank you for taking the time to provide such a comprehensive reply, and for the drawings!
Firstly regarding
Thanks for this. I am on my laptop now, lets see if this ...
@Geoffrey Rea comes out right when I hit submit reply
I do struggle when I am on ipad/tapatalk with mentioning people, quoting etc.
Secondly really appreciate the link to your journal, what a fantastic scape! If I can achieve even half that level of plant growth I will be delighted. Your bolbitis was amazing, do you have any particular tips for this plant? You can see mine is really disappointing. It suffered badly along with many of the plants when I had issues early on due to the mistakes that I made. I wonder if a fresh new pot would stand a better chance?
In your photos I could just about make out filter inlets in each of the rear corners plus a skimmer, but I wasn't too sure what you had done with regards to filter outlets? were they glass and practically invisible?
Regarding my aquarium, I actually have both a green and a black Eheim inlet (my filters were bought at different times and they changed the colour) which I could employ.
However I have taken some measurements and I think I may be able to put the current S/S inlets in the back corners. There is a difference in height between the bottom of the inlet and the substrate at the rear of 4cm on the left and 6cm on the right. My idea is to use a combination of raising them up a few cm higher in their brackets/suckers and putting very small glass jars dug in the substrate below them to give that little extra clearance. With luck the intake slots will not be impeded. I can always give it a go and see what happens.
It’s an odd distribution pattern on the face of it but some valley scapes are like that. If proposal 2 were the desired direction then Co2 would be best deployed from the front left outflow:
I actually have inline CO2 diffusers on both of the outlets so no need to choose!
I may have a play with the two outlets to see whether I can achieve both good distribution of flow (main priority) and preferential sway of plants. My lotus is currently getting pushed into the stems on the left and I would much prefer it to go the other way towards the centre as originally envisaged.
Back in your journal, I read with interest your posts about the importance of oxygenation to the health of the aquarium and I may consider introducing airstones in each rear corner as well. I would only run the air it at night because the air pumps are so noisy, but I hope that would help towards the health of the system.
I also noted that you added an additional branch after initial set up to fill a gap, and I think my scape would benefit from a few extra if I can find the right pieces.
Thanks again for your help and love your work!
Cheers Chris
