MTS and DIY CO2?

778 Views 8 Replies 6 Participants Last post by  Nordic
Hi - I'm planning to get a giant betta in a few months and have just set up my planted tank. It's a 10 gallon tank, my substrate is "Miracle Gro Organic Choice Potting Mix" that I've sifted the sticks out of and capped with black diamond sand blasting sand (30-60). I've got two kinds of java fern, a couple kinds of crypts, and a bunch of dwarf sagittaria. For floating plants, I have dwarf water lettuce and frogbit. Right now, the back of the tank has tall anacharis planted, and I have some loose anacharis floating too, to help take up excess nutrients released from the soil.

Most of these plants I've harvested from my other planted tanks (two other 10 gallon tanks, same soil, builders' sand cap) so I'm pretty confident getting some growth. But - I want some fast growth to start with, so I'm playing with trying to get a DIY CO2 system going. Once the tank looks filled in, I'll return to low-tech - no CO2 and lower lights.

Here's my question - I normally use MTS to keep the substrate turned over and get rid of small plant debris. If I use a yeast/sugar CO2 generator and it's always on, will the MTS's be safe?

Thanks,

These questions pop up pretty often. Is there any livestock that is harmed by properly injected co2?

MTS are tough little critters,I've heard of them surviving bleach .They seem unbothered by ammonia or nitrites too.Besides if they need oxygen,they'll just go to the top and get it :)
BigBadJohn -

You asked "Is there any livestock that is harmed by properly injected co2?" - that's the thing, Iasked about using a DIY system with no regulator and with no solenoid to connect it to a timer. I start my lights in the morning with 5 hours on, 4 hours off, 5 hours on, then off until morning. At best, I'd be disconnecting the line manually *sometime* in the evening and connecting it *sometime* in the morning. And I wouldn't be able to disconnect over the noon siesta.

So I'm not really asking about a system with properly injected co2.
I did try a search for my question but didn't find anything in the forum.

MTS will still be ok. Fish, probably but to be sure you would need a drop checker with proper dk4 and be able to monitor the tank for one day to see if it goes past green to be sure. (or a ph meter stick and then check it several times that day)

You using yeast?
Thanks for confirming the MTS will be ok.

I'm only using CO2 to help the plants get some good growth in the next two months - once my giant betta arrives, I don't plan to do use CO2 afterwards. I'm using soil as a substrate, capped with blasting sand. I like to keep MTS to avoid gas pockets plus they seem to clean up the plant melt. Plus, they should help cycle the tank.

Yes, I'm trying to use yeast. I bake with it all the time, but evidently generating CO2 is harder! I started again this morning and used a spare digital aquarium therm to check the temp of the sugar-water before adding the yeast. Tonight, it seems to be working, still not enough pressure to get through the diffuser, but the bottle is feeling much firmer.
I usually jus mix it all st once and shake up the bottle with the diffuser installed.. usually it shoots a butt load of co2 st once and then it streams out regular like a regular co2 injected tank. Good luck!

Just rememebr to put a bubble counter after the CO2 bottle, it will capture any yeast that makes it through the tube. Yeast makes a snotty mess if it gets into the tank.
The snails will be fine, especially MTS, you will see them climb out of the water and sit on the moist bit of glass just above the surface if they don't like that water.
