Default CO2 in a nano?

Is anyone injecting CO2 into their nano?

What's you setup?

I have a 2.5 gal (12 x 6 x 8 high) that just isn't flourishing like it should without CO2.

Cheers.
Jim

Not yet. Dosing about 1-2 ml per week. Huge algae blooms on the glass a day or 2 after each dose. I'm thinking about switching to a yeast canister with a small ceramic diffuser. I've got a Hagen setup and I'm thinking of taking off the ladder and putting on a Mighty Mini C02 diffusor from AquaBotanic when they restock.

I think the tank might be too cold too (about 65'F to 68'F-room temp). After about 2 weeks, I'm starting to loose my HC. My instinct is to drop in a filter, heater, CO2 injection. Problem is, I just don't have a lot of room for equipment.

Cheers.
Jim

I would hold off on the CO2 injection and try working with the excel first. I have the same tank with a red sea nano filter, no heater, and 36 watts of CF light for my shrimp tank.

I dose about 3ml per day due to the high light. I wind up with a little dust algae on the glass by the end of the week, but that's about it. I'm going to put a nerite snail in for the clean up.

What type of light and plants do you have in there? How long has it set up? What are the water parameters?

I have a 2.5g with HC and dwarf hairgrass, 2 x 13w PC lights, a nano HOB filter and no heater (around 70). I dose EI at 50% daily and I dose Excel 2x which is .36ml each day (6 drops at .06ml each). I do weekly water changes. I have no algae problems. There's nothing in the tank but some limpets that hitched a ride.

If you are dosing one big dose weekly, break it down into smaller daily doses. I think steady levels are much better than dumping a lot in at once and then letting it run out.

3ml a day into 2.5g?! Wow. I dosed 30 drops into my 10g with 65w of PC light and that only equalled 1.8 ml and was 2x the normal dosage.

My water parameters are:
pH- 6.0
No2- 0.30 ppm
NO3- 25.00 ppm
PO4- 0.00
HG- 2.50
KH- 2.00

Plants are Hemianthus callitrichoides, Lilaeopsis novea-zealandiae, Monosolenium tenerum, and a piece of what I think is Micranthemum umbrosum that was a hitch hiker in the Monosolenium.

I know my NO3 is excessive and that's part of my problem. I'm on well water and since we have a huge corn field next door, the excess nitrates have leached into the well. I know I should add some phosphate or use RO water to counter the nitrates and was hoping to get away with a little PO4 and CO2.

I'm running an 18 watt CF and have a Red Sea nano filter but haven't set it up. I also have no heat. Oh, and the tanks been up for about 3 weeks.

I think you're right about the Excel swings. For some reason it didn't occur to me to use an eye dropper for dosing a small tank. Thanks!

Hopefully this will cure my HC decline too.

Cheers.
Jim

i think adding phosphate will solve your algae problems, and potassium and traces too if you're not already doing that

Nano CO2 can be achieved by adding a valve to the DIY CO2 your making so u can get a better control of the bubble rate^^ just my 2 cents that worked

I've got a modified eclipse explorer II with an airstone placed underneath a rio 90 powerhead at 3/4 power (with yeast Co2). My anubias pearls like crazy! I'm still trying to get a small ceramic diffuser instead though.

Well I stopped the excel and switched over to yeast CO2 on Sunday. I took a Hagen Plant-Gro CO2 Natural System I was using in another tank and replaced the ladder with a Red Sea micro bubble diffuser.

The algae and loss of my remaining HC has stopped. Hopefully I'll get some actual growth now.

Cheers.
Jim
