Soylent Green? Algae Farming
Posted: Thu Mar 30, 2006 8:59 pm
I finally decided last week to bite the bullet and set up one of my empty tanks as an experimental algae farm to grow algae on stones to feed Hillstream Loaches.
I know that others have been doing similar and decided my situation here makes it a somewhat easier task than for many others. I live in a penthouse apartment with a huge West-facing balcony. It gets masses of sun and there's a nice wall between the balconies which means I can put a tank in a relatively sheltered position in the North East corner which means it gets all the sun from the soth and west as it moves around.
When I first set up the 15"H x 16"L x 15"W tank we had sub-zero overnight temps, so I put in a heater to stop it freezing. I filled the tank with old tank water from my Clown tank. Added some algae wiped from the front of the 120 in the bedroom and various rocks with growths on from other tanks. Also put in some clean pieces of slate. I added a short air wand as someone said it would help gaseous exchange, plus I don't want the water stagnating.
Fertilizer would be good right? Added a few splashes of Hydroponic fertilizer that Momfish has used for years in planted tanks.....and a secret ingredient.
While back in England, I had a planted tank with no fish and with Momfish's encouragement via phone from Canada I tried an experiment based on a story she heard from the kid's Summer Camp. At the camp, all the girls used to swim in a small bay in the lake. It had luxuriant aquatic plant growth. One of the ladies in charge gets all "eco" on the girls and works out that if a certain percentage of them pee in the water while swimming, in a given time they are excreting a 50 gallon drum-full. So she places a blanket ban on peeing in the lake.
The plant growth died back drastically......go figure.
So my plant experiment worked quite well. I guess you could call it self-propelled Figured that it ought to work on algae, so using my self dispensing equipment I filled half a mug and threw that in. If you ever come round my place decline offers of tea or coffee
I added a second heater a few days later because the water still felt cold.
A few days later.......voila!
Hubble-bubble toilet(?) trouble
So today I lifted out a couple of stones and placed them into the main River-Tank....not bad growth eh?
An inquisitive Aborichthys elongatus was the first to check them out.....
Next came a hungry Pseudogastromyzon cheni......
......who really got into it.......
He was then joined by a Gastromyzon ocellatus (left) and one of my undescribed species Gastromyzon (top)
.
The three of them were really going to town.......
......inbetween minor altercations between themselves.
......chomp, chomp, chomp.
One of the UFO's checks out the other stone. As yet, none of them have really got serious with this one. The algae looks like another species.
This species is really broad and blunt. If it keeps eating like this it will get broader!
So, seems like the diners are satisfied with the recipe. Now I have to see how quickly I can get a rotation of stones going. Next diners to test this out will be the Sewellia. See what they think.
I'm going to pull that white stone out now and put it back in the farm. I'll take another pic in a few days to see how it regrows.
