Grow Your Own Phyto.

Algae: a liquid culture. Most reef shops grow there own Phyto and they will sell you a 16oz bottle. Or look on E--y. The Phyto culture needs to be a single strain.
Fertilizer: 1 bottle of essential elements
Culture containers: 1 cleaned, rinsed, with caps, 2liter soda bottle (round bottom perferred)
Lighting: inexpensive Home Depot shop light (dual 48” bulbs), or a dual bulb 24” inch
2-4 fluorescent bulbs (6500K is sufficient)
Aeration: 1 high-powered air pumps, either with 2 or 4 outlets, controllable. The more bottles you have the more air you’ll need.
2 or 4 outlet gang valve(s), metal or brass tends to work better than cheap plastic ones. Sufficient 1/8” flexible airline tubing, 1-2 3 foot long rigid airline tubing.
Other items: Aquarium salt, salinity hydrometer, plastic, plastic medical syringe (1-10mls: for measuring volumes of fertilizer).
I use tap water for my cultures. I think there are thing in the tap water the phyto needs. You can also usr RO water.
I small 10 gallon fish tank with the sides and back painted to keep the light in. Place the light on the front of the tank, I find this works best. Placing the light over the top works well also.
Ok Here we go
Drill a hole in the cap to the 2 litter soda bottle to fit an 1/8" air rod through. Slide the air rod through the cap and in to the bottle until the rod is 1/4" off the bottom of the soda bottle. Let abot 3/4" of rod on the outside of the cap to attach you air line to.
poor you culture of phyto into the soda bottle
Mix some salt water with a solinity between 22 and 25. I run lower at 18 to 20 I think the phyto grows faster.
Add 5ml of essential elements to the saltwater mixture.
Note: Make your salt mixture in a tall pitcher.
Top off phyto in the soda bottle. Shake well
Attach air line to air rod and set bubbling at 15 to 20 bubbles per second.
Turn on light. Phyto needs 12 to 16 hours of light each day. Best to use a timer.
Let bubble 3 to 4 weeks read to use.
When drawing small amounts of phyty from you culture you will need to top off you soda bottle with the saltwater and essentals elements mixture.

As your culture start maturing and turs very dark green you can start splitting bottles and get as many bottles as you want going.
If you cultur turns clead its toast. If it turs brown its going to die on you. You should have no foam on the the top during the bubbling process. If you get foram cut back on your air. Just keep the phyto moving. Dont over bubble. Shake your bottles every other day. This help with keeping the thicker phyto frm setting on the bottom of the bottles.
I like using Pyrex glass bottles. They can be cleaned. Soda bottles get green after a few months and you need to replace them.
When you make your salt mixture in a tall pitcher it about 2oz of salt on a scale. Add the essential elements into the water before topping off your cultures. You can add some merical grow also about 3ml but I never do.
Make sure all salt is disolved
You can store the phyto in yor frig for weeks as long as you shake it every other day. I have some extra 16oz bottles that as my cultures grow I fill the 16oz bottle and store them and feed my tank. This way I keep my cultures going strong.

No Problem. If you can Find a culture of Phyto let me know. I some times sell a 16.oz bottle from time to time so people can get started. I charge $30 plus shipping $10

You can but don't try it. DT bottles have 3+ species of phytoplankton. If you culture it, the strongest species will survive. And, the strongest might not be the most nutritious to your animal. It is easier to start with a mono-species culture.

3 different types.
is there any added benifit if you cultured two or more different types, mixed then use?

The green algae wasnt on the glass, it was the water that was green in the tank, so using a mag-float would of been useless since it was the water that was green lol

Yes, that would have been a phytoplankton bloom.
:joy:

Most definitely. And this is the basis for multi-species DT Phytoplankton.
DT has nanochloropsis (4-6 micron) which is good for rotifer. The other 2 species, assumed larger, in DT are prefered by clams, which like phytoplankton in the range of 4-40 micron.
