H2O2 spot treatment on nana roots ?
I have recently had great success with a 2-3min peroxide soak of crypts & nanas to remove all algae (BBA, GSA, & fuzz) from the leaves. I also scrubbed the BBA off w/ a dish pad prior to the soak. This however required up rooting the plants. I was very careful to not soak any roots in the H2O2 as I was unsure if this would kill the plant since they were already in super poor health (transparent, half of the leaves have major holes, many missing 25-50% of the leaf).
I'm in process of redoing the tank and am almost complete (pressurized CO2 in place, new high light LEDs in place, root pellets in place, will have another powerhead and 2 drop checkers in place by weeks end, and fertilizers in hand next week to begin EI). I've never done any sort of fertilization or CO2 until now.
Now that these plants in poor health are showing pearling and a lot of new growth for both leaves & roots I want to finish knocking out the algae before I begin my EI fert dosing regiment next week.
Now the questions:
- Without having to remove the plants from the tank or from being tied to driftwood can someone tell me if it's safe for the roots & stems to accept H2O2 spot treatments to kill the remaining BBA (after turning off all flow to tank) ?
- If so how long before turning back on the filter, CO2, & powerhead ?
- As for the fresh green spot & fuzz algae on the leaves (including new growth) can I spot treat those as well in the same manner or do you think this stuff will simply go away (after a week or so of dosing) after I begin my EI dosing and therefore not to bother with treatment here ?
- Or would one suggest a black out instead and if that doesn't work do the 2-1 punch after another black out ? I'm hesitate for this option due to such poor plant conditions as it is.
