Time to Grow Up

Next year , probably around June or so , I intend to set up a 16 gallon bookshelf display tank in the living room . I don’t want to mess around with growing in plants in this tank ; rather my goal is to use plants that are ‘pre grown in’ in a couple of farm tanks in my basement , and transplant them over when the time comes . Unfortunately ; I’m out of rack space , and have some small pots of plants that need somewhere to go . I could stuff them into an existing tank ; but I may have some interesting new fish coming in a few weeks that will probably need some space to mature , plus I can experiment with a few things that I want to do on the ‘good tank’ re: substrate , lighting duration and ferts. Better to have things fail on something that’s temporary and less important .

So I’m resurrecting a 30 cm. cube as a farm tank for the purpose . This will not be a nice display tank , just something to monitor plant growth!!! It’s been sitting empty on my porch for a few years and needs something to justify its’ existence . Not too big so it won’t litter up my kitchen counter , but big enough (I think) for the proposed uses . Nothing special about equipment … a Sicce ‘Micro Nano’ internal filter with a piece of 20ppi Poret foam in it that’s currently been‘charged up’ in an established tank for a week or so, and a Finnex ‘Planted Plus’ that was on the tank a few years back when it was last set up. No CO2 , auto dosers , drop checkers , diffusers , or other impedimenta that so frequently is found littering up folk‘s tanks . Just a bare bones , minimum , ‘old school’ low tech setup . No tinkering with water parameters , just the stuff from the kitchen sink , Ph 7.4 , dH + kH both around 8 to 10. It’s getting filled with ½ tap water and ½ used water from one of my existing tanks.



I’ll be using CaribSea ‘Super Naturals ‘Peace River’’ which is a small grained inert gravel . I think I’ve got enough for 1 – 1 1/2 inches depth . I’m also going to try a thin (1/8” or so) layer of leonardite laid down over ½” or so of the gravel and then overtopped with the remains of the gravel . Just to get some organics into the substrate . Barr mentions this stuff as an additive in his 2005 (?) article on non Co2 low tech tanks . Plus I’ve got some sitting in the garage that I got a while back for some experiments in growing tomato plants in containers and need to use it for something . I’ve used finely milled sphagnum as an organic layer and while I’m not so sure if there were benefits , it certainly did no harm save for imparting a slightly brown tint to the water , so we’ll see how leonardite does in comparison . I’m also breaking open 2 Osmocote tabs and distributing the contents into the leonardite layer to get some substrate nutrients installed . Between the leonardite and Osmocote I should have a reasonably enriched substrate to plant into . I don’t plan on water column dosing for 2 weeks minimum after setup . Going to play it by ear with this.



Right now, the tank is planted with 4 or 5 Crypt. ‘Florida Sunset ‘ ; and 10 or so Crypt. ‘Tropica’ . all of which have been separated from rooted masses in small pots I got online . After separating the plants , individual plants were placed submersed in trays for a few days until I could get the tank filled . At this point some of the ‘Tropica’ decided to melt . I planted the roots anyway , usually they come back , just takes a while . Pix when the water clears up .
 
Not the most exciting image , but it represents a place to start ... a reference point .There's 3 different Crypts in here . Across the back - C.'Florida Sunset' ; next closest ; C. 'Tropica" ; and closest some C. parva which I moved from a tank downstairs where it was doing nothing to this tank where it probably will do the same . Plus a couple of pieces of Frogbit and some Red Root Floaters

Added a small ball of Riccia in an attempt to get a duckweed free sample . I also added about a 3 inch piece of hornwort . Just as an experiment to find out exactly how fast this stuff grows in my tanks .

Fert. dosing has begun . Was going to wait another week , but decided to start now so I’ll be doing biweekly dosing at the same time ( around the 1st and 15th of the month) as the rest of the tanks I’m using ferts on. Low light EI weekly as calculated using Rotala Butterfly . Solutions calculated for 10ml / 10 gallons or 1 ml. / gal. . Dosing KNO3 and KH2PO4 , Micros (Miller’s Microplex)and Iron (11%DTPA) . This is pretty lean , but has worked for me for the last 4-5 years .

And a FTS , not that a lot has changed …

It’s melting ! Actually , almost everything (except the stuff that was pre-melted before planting) went down about 2 weeks back . Took its’ time , but I’m not terribly surprised . The floaters , however are doing great .

Picking up a bit of algae on the tank sides , but that’s going down due to the mass of floaters cutting down the light . Plus the snails that miraculously appeared are probably helping out some , too . Hornwort’s about doubled in size .

There’s been new growth starting in the crypts , which is a good sign . The only thing I’m not particularly pleased about is how the tank’s doing re: the duckweed index . The floaters are doing great , but the accursed duckweed has reared it head . Must have been a molecule that followed the floaters over from a basement tank . Gotta keep an eye out to make sure it’s gone .

Enough excitement for the month ....let's see what happens in the next few weeks.
 
It'll bounce back! Looking forward to the recovery. 😉
Yeah , it'll just take some time , maybe 2 months or so for the crypts to look like something again . I've got something similar going in my basement with crypts from the small pots that melted back in August , and they look fine now . Just have to keep shovelling out the floaters . I pulled out a small take out container of floaters the other day , and it looks like it's filled in again . Not complaining as I've got folks in one of my clubs who'll grab any floaters I bring in .
 
So another month has passed with this thing . Partial water change , 20% or so 2 weeks back ; ferts as per 2 months ago . The floaters are still growing crazy , to the point of blocking a bit more light than I'd like .

Keep pulling them out almost weekly . Getting one of these each time , which gets dropped into one of the tanks in the basement .

Anyway , this opens things up some re: light .

The crypts are doing pretty well considering the 'low techness' of this thing . Just gotta wait it out .

No doubt that everyone will eagerly anticipate more excitement next month 🙄!

It looks to me like they have turned the corner now, I love planting them, watching them melt and then slowly come back better than before, the world of chilled aquascaping!
 
In many respects , this is the ideal tank ..... almost no maintenance save for top-ups , ferts every 2 weeks , and scooping out floaters . I think what will be happening now is that the crypt's growth will be limited by their ability to develop supporting root systems . I don't plan on breaking this down for at least another 6 months or so , so am anticipating harvesting a tank chock full of big crypts at that time .
 
Well , this certainly sucks . Seems I've got another , at least partial , meltdown going on . Happened fast . Checked water parameters as best as I can and got Ph 7.4 , GH / KH both around 8 , PO4 .5ppm , NO3 40+ ppm (!) , can't check for K , iron , and traces . No drastic temperature changes . No water changes since last post. No ferts until next week . Ideas anyone?

One question: NO3 is 40 ppm? Is it NO3 - N and NH4 - N together or only NO3 - N. In my experience crypts don`t like to much NH4 - N. But there maybe too much NH4 if you see algae. KH 8 is fine and Ca - Mg - K should be about 4:1:1 or similar like 4:2:1 or 4:2:3. All these should work.

Only NO3 , the tanks been algae free for a few weeks , the algae in the last picture in Post 7 is gone .
