read the posts on pages 2 and 3
thanks for the comments and suggestions.
I'll post some more closeup pics of the plants and fish later tonight!
Do you think I should just remove the biowheel from the filter? It still has 1 carbon insert (plus an extra carbon insert, to create a biological filter ready for QT tanks).
It should help with your current configuration regarding DIY Co2 working with HOB filters, DIY mixture, Diffusion methods 'important
', Photo-period and dosing routine. Yes get rid of the Carbon media, if anything use Purigrn it has little or no impact on ferts. The tank shown is using DIY co2, much higer WPG and is actually my test tank but you get the idea.
And I am dosing my tank with only 2 things regularly:
1. Flourish excel... I add about 1/2 capful every other day roughly.
2 Iron supplement. I don't have the exact ingredients right now, but I can post back with what it contains later tonight also.
See above reply for dosing above or read here
in its entirety to learn what ferts to use, where to purchase & when to dose ferts as well as other helpful information.
A few weeks ago I used alkalinity buffer (I think its from seachem), since my dKH used to be only 3 degrees.
This is not necessary and is fine for your plants....mine is 0~1dKH
Could by actinic bulb be making algae worse? Right now I am running actinic for ~10 hours, and daylight for ~6 hours (LFS told me to start with lower time for main bulb and slowly increase).
Get a DC 'drop checker' to verify proper
Co2 range right now it's only guess work and if diffusion method is no good you will have algae issues 'which is more likely the culprit' and start a better fert routine after.
I might try removing actinic for now and increasing daylight bulb duration to 8 hours. Thoughts?
Get rid of the actinic. No...what you want to do is lower your photo period or WPG so I would leave it a 6hrs only no more until you figure out you Co2.
"How many bubbles per second do you have floating up that ladder?? You should be able to keep up with DIY co2 for a 20g, but it's definitely a PITA. To help with learning about nutrients, I'd visit Rex's website (rexgrigg.com)."
The bubble ladder usually has about 3-5 bubbles climbing it at any given time, and I'd guess that a bubble gets made every few seconds.
I scanned the rex site last night, and saw that he says testing for iron is useless????? This is the only thing I've been dosing with so far. more details later!
Read the first link for ideas that work to get and maintain proper Co2
levels Co2. @ that light level it is very important but you will also have to start a better dosing routine cause you will be kick starting your plants. Everything you need is in those links...read and good luck!
