Here is a quick update -
The HM and Rotala were trimmed back last week and will soon need it again. The HM in particular is looking a bit 'wild'
I've changed the CO2 tubing for some black and it's now practically invisible against the black background. But I've still got to do something about the really ugly Fluval filter intake/outflow. If I dont replace them I may do as George suggested and paint them with black acrylic paint.
Does it need to be treated in anyway if doing this ?
3 weeks after setup:
(the foreground is not actually as 'yellow' as it looks in the pic ... photography not being my strongpoint!)
The water stats have now settled. The initial huge ammonia spike of 5mg/l (as high as the test kit is able to go!), dropped to 1.5 mg/l within a few days, then down to 0.3mg/l and finally down to zero, where it has been for the past few days. During this time there was NO livestock in the tank. I doubt much would have survived in there.
Current water stats:
NH3/NH4 =
0
NO2 =
0
NO3 =
20 - 25 (a bit on the high side)
PH =
6.8
KH =
7 degs
CO2 =
33ppm (using chucks calc) - with 2 bps
Ferts:
ADA Step 1 - Daily
ADA Brighty K - Daily
The PH had dropped to about 6.5, but now seems stable at 6.8. I'm monitoring this and the NO3 every day or two and will take action as appropriate. A water change with my normal tap water (PH 7.6 )should be enough to up the PH if it starts to drop again. I may use a few floating 'water lettuce' for a few days to suck up some of the NO3.
I've not seen any real problems with the using the Aquasoil, some clumps of the U. graminifolia have floated free and had to be replanted, but with the roots on that plant, I think that would happen with any substrate.
The tank has suffered from a bit of algae, mainly diatoms low down on the substrate, The only algae I'm worried about is the black bush type stuff that has developed within the past few days but only on some of the Lilaeopsis mauritiana ....
could this be due to the NO3 reading ?
As the water stats have been stable for a few days, I decided to get some shrimp and otto's in there yesterday. I got a good price on 10 shrimp from my local Maidenhead Aquatics, and then found he'd given me 11 ... so an even better deal.
Overnight they have made short work of the diatoms and the tank is almost clear of them.
The black stuff is going to be more of a problem to get rid of, I think I may end up having to removing the shoots with it on.
Anyway, here's a few more pics .......
These pics show how the Utricularia graminifolia has developed :
23 Aug - 4 days after planting
03 Sept - with shrimp doing a clean up !
Note: The direction it is laying, is the same way as the direction of water flow around the tank.
03 Sept - Side view of tank:
And finally one of the Prosperpinaca palustris "Cuba", the leaves have started to take on more of a needle like shape and it is developing more of the copper colour. This was planted to complement the reddish colour of the bogwood. (Those shrimp get everywhere ! )
Cheers
