What are your tap water parameters. pH, GH, KH?
Substrate?
How much pmdd are you dosing? How much excel? How often?

You could easily get away with DIY CO2 for a tank of that size, pressurized will just save you from making a yeast mix every 3-4 weeks. But a 2.5 is easily small enough to not need pressurized.

23W screw in - any idea what color/temp that bulb is? Is this by any chance a 2.5 Mini-bow?

I agree with jhoetzl.....try DIY.... some plants don't react well to Excel- it causes them to melt or die.

30g planted with cories, white clouds, Harlequin Rasboras ,ottos.
10g planted with glowlight tetras and an otto.
Outdoor pond with one common goldfish and comets.
5.5g with endlers.

I don't know my parameters. I don't have test kits and I don't want to buy test kits. This is not my first time with planted tanks. I had planted tanks a year ago and decided to get back into it a month ago. I just want a small planted tank without all the equipments but I guess without pressurized co2, my plants will not grow green and healthy. I don't know the K and CRI of the bulb. I'm guessing around 3000 to 4000 k and a CRI of around 60. I know those are not acceptable numbers for planted tanks. I'm thinking about buying a new 42w daylight 6500k, 84 CRI from Goodmart(http://www.goodmart.com/products/74298.htm). 5ml of pmdd every 3 days and 5 ml of Excel every 3 days.

Aren't you overdosing the excel? I think I calculated 2x normal dose for 1.2 gallons being .2ml a day, so that would be .6 every 3 days x2 for your volume comes out to 1.2ml every 3 days to get 2x the usual dose.


You're dosing more along the lines of algicide use aren't you? I'm new to excel.

I would think if the java moss was dying your problem lies outside the realm of Co2 starvation. I dunno how those 42w screw in fluoros compare to regular fluoros for light output, but I know 45-50 watts of PC light is plenty plenty for a 10 gallon. Your current problem may be spectrum rather than intensity. I'd stick with light in the mid 20s or the equivalent in screw-in.

I'd make sure your excel dosing and your light are taken care of before I would worry about injecting Co2.

Probably need to at least find out the water pH and Kh and GH. Those Aquarium Pharmaceutical full FW test kits are very cheap to buy at Big Al''s etc. online. Probably alot cheaper than new lights etc.

It sounds like a lot of light for that sized tank. PMDD type dosing might be limiting the uptake of one of the macros or micros. You may need more targeted dosing... I'm thinking you are possibly over dosing too. Do you have any algae problems with that much light? And how often do you do water change? Good luck

Every 3-4 weeks? I'm lucky if my CO2 injectors last a week at full bubble rate. Not sure what I'm doing wrong if anything..... Maybe I should start using brewers yeast instead of wine yeast and see if it helps.

Yeah, I wish I was 3-4 weeks out of my DIY CO2! I change the bottle weekly, using bakers yeast. Nav, let us know how you get on if you try something else out and it works.

I will, i just have to find some brewers yeast. There's a restaurant around here that brews their own beer and my aunt is friends with the owner so that's probably my best bet. I get big bags of wine yeast for like a buck from a local wine making school. Brewers yeast has been the worst for me, last time I tried I didn't get any co2 from it but I may have had a leak in the injector also. The silicone on my inject just peeled off completely so I'm making a new one today with plumbers epoxy, hopefully that will bond to plastic a little better.

If you can find Champagne yeast from a brew-it-yourself, try that combined with the jello recipe. I found it lasted longer with a lower output.
