    Starting new tank - codename Frankenstein - critique wanted

    Hi,

    I'm about to start a new tank and I could use some advice. Here's what I plan to do - please point out any mistakes/risks.

    Why "Frankenstein"? I "constructed" the hardscape from several small pieces of wood glued with silicone. The result:

    (it's quite different from what I had in mind when I started )



    The tank: 75cm x 45cm x 45cm (30in x 18in x 18in) = 150l = 40gal
    Hardscape: wood (see above)
    Substrate: plain quartz sand, about 10cm average depth, as sloped as I can make it
    Water: dechlorinated tap (GH=9, KH=5, pH=7.3 but in the tank pH will be around 6.5 due to CO2)
    General aspect: West Africa biotope-ish (it will have more plants than a typical biotope, and the look will not be authentic I suspect)
    Filtration: CPR CR900 Wet/Dry with Eheim compact+ 2000 pump (2000l/h = 530gph theoretical but this will be throttled by the narrow tubing of the Mame overflow)
    Light: ADA Grand Solar II with 4 x 36W tubes; I plan to set the height so that PAR at substrate is between 75 and 90mol-6/m2; in time, the substrate will be shaded by floating leaves; schedule: 10h continuous (less in the beginning)
    CO2: pressurized, around 50ppm, still not sure about diffusion method (reactor/NW pump/other); schedule: like the light
    Fertilization: EI daily (maybe buy dosage pumps for micro/macro?); weekly 50% water change
    Other hardware: Tunze Osmolator top-off pump (using RO water)
    Critters:
    - 4 Pseudocrenilabrus nicholsi (1m + 3f - if I can't, at least he can )
    - 8 Congo tetras, Phenacogrammus interruptus (any other good suggestions that would fit this tank?)
    - I don't know what to use for cleaning crew
    Plants:
    - Anubias nana tied to small pieces of half-buried wood, scattered on the sand as "foreground" plants
    - The hardscape will have lots of either Bolbitis heudelotii or Anubias (coffeefolia?) tied to it; some of these plants will grow emersed on top of the Frankenstein log; probably Bolbitis though
    - One of the sides will have two Tiger lotuses (lotii?) very close together; one will be allowed to grow surface leaves; the other will be kept submersed; I hope they will look like one plant with both types of leaves (?!)
    - The background will have some Crinum sp
    - If I want to keep with my W African theme I could also use Eleocharis parvula (but I am not sure how it matches with the rest), or Ammania sp (but I don't want stems in this tank)

    The goal of the tank is to be lower maintenance than a stem tank, but I accept some weekly maintenance at water change time. When it matures (and my enthusiasm decreases ) I would like to be able to dial back the fert regime and water changes, and make it "low maintenance".

    For the cycling phase I am not sure if I need fast growing plants or if the final slow growers will be enough.

    Any advice, hint or criticism is welcome.

    Thanks,

    Florin

    Hi Florin,

    That is a LOT of light for both the plant species desired and the goal of low maintenance...

    I think 40-50 mmoles will do you fine....
    Thanks,

    Gerry.

    Good point, thanks Gerry.

    I can start with less light (40-50 mmoles), and increase it when floating leaves shade the tank too much.

    Love the onions! One of my favorite plants. The plants look really nice. Good luck on the setup. Post finished pics.
    Thanks

    JJ

    Plants give me peace!

    Ionuț, Jerry, thanks.

    Here's a quick setup timelapse.



    In the meantime things happened - most leaves started to melt, others started to grow - more pics & info soon.

    Some pictures from the setup (March 12th).

    The right side wood turned belly up (wasn't soaked enough it seems).

    A lotus right after planting:

    End of the day (2 a.m., March 13th):

    March 14th pic of the Frankenstein log:

    Yesterday, March 18th.

    Ignore the foreground plants tied to rocks, they're not in the final positions.

    The "data" room (too dark, I know):


    IMG_0337 by florin i, on Flickr

    The monitors didn't fit inside.

    Bolbitis (old leaves start to melt but new growth is also visible):


    IMG_0274 by florin i, on Flickr


    IMG_0273 by florin i, on Flickr


    IMG_0294 by florin i, on Flickr

    The small log soaked and is in the normal position. I will try to use the anubias bound to pebbles to mask the ugly ties.


    IMG_0292 by florin i, on Flickr

    The dirt is from washing in this tank a sponge from an established filter. In this are I think I have insufficient water flow (or else the mulm particles would be washed away - right)?


    IMG_0266 by florin i, on Flickr

    Some anubias leaves start to deteriorate:


    IMG_0268 by florin i, on Flickr


    IMG_0295 by florin i, on Flickr

    Others seem OK so far:


    IMG_0298 by florin i, on Flickr

    All the old lotus leaves melted away, new ones appeared:


    IMG_0271 by florin i, on Flickr

    Crinum leaves melt quickly from top to bottom (I understand that's normal?):


    IMG_0275 by florin i, on Flickr

    The biggest Crinum has one half leaf left, the others melted:

    Some color:

    I lifted the lamp as high as I could and now the PAR at the substrate is around 60 micromol. Current light period is 6 hours. With CO2 I target 25-30 ppm (is that a good range for this tank?).

    I will add a bunch of floating plants to help with establishing the tank.

    The only fauna for now are some snails. I will also add some shrimp - and then the fish - I hope to find some Pseudocrenilabrus nicholsi, 1m+3f, and some Congo tetra.

    Most plants seem to have stopped melting. No big starters yet but signs of growth everywhere.

    The melting did leave a lot of vegetable matter. I tried to remove as much as I could but I'm a little worried about algae.

    CO2 is stable at 30 ppm. I am ferting around 1/4 tsp KNO3, 1/16 tsp KH2PO4, 1/16 tsp PLANT PROD Chelated Micronutrient Mix. I did some measurements yesterday before water change and:
    - ammonia is zero
    - nitrites are high (over 0.3)
    - apparently I went overboard with phosphates (over 2.5 ppm which was my test's limit)

    The glass shows a very very discreet brownish layer (diatoms, expected) and slightly greenish (GDA?). Both colors are only visible when looking almost parallel with the glass.

    I added some floating plants to help mature the tank:
