Co2 @approx 3bps, daily dosing 3ml lco2 and ferts, reduced light intensity, ocd daily cleaning, 30% water changes every other day and still I just can't win.
Up your water changes - this is ADA soil, so I'd try their recommended protocol of
large (as in up to 90% depending on the tank, & 50% being the strarting point) daily water changes
That muck growing on the wood, means lots of organics, so again, I'd do larger, daily wc
I'd also be vacuuming most of that mold/slime off in daily maintenance
Add a crew of snails, shrimp, Otos to help control the mold/slime & consume algae's - these guys will be cleaning up algae before it's even visible really, not waiting until there are massive (visible) amounts
(which is why they'are so effective in new setups)
I rescaped a 60 x 45 cm tank 3 weeks ago, minimal algae (I noticed a bit of diatoms on the Anubias yesterday) BUT that's most likely down to rapid "auxiliary" plant growth (rather than my excellent care
) - the tank is basically full of green growth, in another week or so, I'll begin removing some of the fast stems, allowing more room/light for the slower plants. This is best done gradually (just like trimming) rather than all in one go
I realize this is just a few pics of your tank, but I don't see a significant mass of fast growing stems ...
AR mini usually takes 2-4 weeks to get going, & even then remains a moderate rate of growth stem plant so rather than getting more of this right now, I'd invest in "auxiliary" plants
You might try increasing CO2, but also ensure good oxygen levels - Twinstar Nano is defineitly good at this
- you can also use a skimmer or raise spray bar in the off-photoperiod
This aquascape isn't an easy one to start
