So this is a journal for my new 120, which replaces my long running 75 gallon. For anyone who followed the previous tank,
this one will be basically the same style with just a bigger footprint.
It's going to have many aspects of a traditional Dutch, but probably never meet all the criteria. The main thing being no planted back and sides. Also collectoritis will most likely mean too many species to ever be a true Dutch.
But Im not worried about all that. The goal is to have fun and do what I like. Which is put colors and contrasts together, play with trimming/pruning techniques, learn more about the horticulture side of things
Hence the name - Dutchy Freestyle.
First planting, about 2 months ago.
48" x 24" x 24" Marineland 120 gal
GLA Grow 1 regulator, 10 lb tank.
DIY PVC reactor. Main pipe is 3" x 24"
CO2 cuts on 90 min before the lights, goes off 1 hour before. PH drops 1.1 by lights on, proceeds on down 1.3-1.4 at peak. Livestock are fine at this level, heavy flow and good surface agitation helps.
Two canisters: 1 Aquatop CF 500, and 1 Hydor Pro 600
Measured flow combined is about 600 gph.
1 Koralia Nano 425 for added circulation
Both canisters have SunSun intakes with the skimmer
Left corner is the the Aquatop. Using a 1" outflow pipe to reduce velocity (the in-tank flow is crazy!)
Right corner is the Hydor. The CO2 runs inline with this one.
^also you can see my LED night lights, mounted on each end of the main fixture.
Black Diamond blasting sand
6 bulb T5HO hydroponic unit
Bulbs are front to back:
Fixture is 9" above the tank, PAR at the sub is around 120. Having lots of red bulbs help keep it down, not to mention awesome color rendition. PAR would be a lot higher at this distance with more 6500Ks, for example
Macros 3x week
6 ppm KNO3
.5-1 ppm K2PO4
3 ppm K2SO4 (for 6-7 total K)
Micros 3x week
.01 Fe from csmb
.02 ppm Fe dtpa
.2 ppm urea daily
This is the general range where most things do well for me, all subject to change of course, as anyone who knows me knows.
60%-70% water change every 6-7 days
The basic philosophy is high macros, low micros, nosebleed CO2, uber clean conditions and maintaining a stable biomass
12 Harlequin Rasboras, will soon get this up to maybe 30 or so
Trio of young German Blue Rams, just coming into their adult colors
May introduce the Fire red shrimp at some point. All the ones from the 75 are in a 10 gallon and breeding like crazy. Not sure if the Rams will bother them too much or not. May do a hoard of Amanos and see how that goes.
Here's the latest rendition. Plant groups are no way shaped for height or footprints. Mainly just tentative placeholders of where things are going to be. Have lots of ideas to try, and open to any suggestions!
