Can anyone help me troubleshoot my grow out tank for some buce and anubias?
It's about a year and a half now, and from the last 6 months, plant mass has started to decline. No matter what test or ph pen i try, I can't get more than half a point of ph drop (resting is 6.5, it sometimes goes to 6.0 after the co2 shuts off but never lower). The outlet of the filter is totally cloudy from microbubbles, I've checked for leaks, and everything seems okay. the first 3 months were hugely successful with almost every plant flowering, but eventually I started getting unmanageable algae, so I stopped dosing and now that the algae is gone, but plants aren't impressed. I'm up for going back to EI, investing in better lights, or whatever - but I will need to fix this co2 issue first. To me this seems like a very basic issue but somehow I just can't get past it.
Some info about the tank:
40g, inline diffuser @ about 10bps. Oase biomaster 600
30W of some rip off LED. I tried as hard as I can to get the manufacturer or light specs, with no result. They only advertise "2862 lm".
6 hours of light, 7 hours of co2. co2 goes on 2 hours prior to lights, and shuts off an hour before the lights go off.
3 big pieces (forearm sized) of unknown wood. It's very soft, and i can easily scratch dents in it with my fingernail, bought from LFS. It's kind of making a mess and algae is growing more on this than anywhere else.
3 fist sized pieces of granite holding the wood in place
2-3 cups of aquasoil in the back for crypts, with a very light layer of pool filter sand covering the bottom of the tank.
happy colony (maybe 30-60) RCS, 1 betta.
Tank has about 20-30% plant mass. Java fern, crypts, moss, anubias and buce.
I do about 10 big sprays of h2o2 after every water change, weekly.
My original assumption when algae started picking up, is that my dosing wasn't right. So i measured it all up, checked it twice, and then bought a cheap dosing pump where i dosed macros once a week and micros daily, as per some advice I read here, along with a co2 reactor. Algae returned, just as it did in the past. The only thing that's left is that this is the result of inadequate co2. But no matter how much i increase it, i can't get that drop. Any advice to help me move forward, at all? I'm tempted to reset, but this is a problem that should be easy to fix and I don't want to miss out on a good learning opportunity. Why am i struggling? How can I make this thrive?
Thanks.
edit:
I totally forgot about a post I made about this tank a year ago. Since then, it's been mostly fert free. Though there has been some growth since, the same issue persists.
