Hi all,
I would like to share my recent experience using h2o2, aka hydrogen peroxide on my 300l tank.
On my current battle on the algae issue I have, I followed the advice that I received here on the forum and reading other people experiences on lowering the photoperiod and treat spot with h2o2 (15ml/dose) and Easy Carbo / Excel (12ml/dose) on alternate days combined with 2-3 x 50% water change per week.
Yesterday, I decided to increase the water change to 75% to expose to air more of the rocks and lower part of the affected plants.
So, I lowered the water (fish, shrimps and snails all in) and I did one of the biggest mistakes ever (if not the biggest). SPRAYING H2O2 ON LOW WATER CONTENT.
The intention was to spray peroxide on rock and wood to accelerate the process of killing algae. What I did not realize is most of the drops will end up in water. Basically, I was pouring 6% hydrogen peroxide all over my fish.
The result was absolutely disastrous, 20 out of 30 cardinal tetras died on spot and further 5 died in the course of next hours along with one of the 2 red phantom tetras.
What did not make any sense, the zebra danios are OK, the only molly same OK, red cherry shrimps and snails not showing any signs.
Lesson learned on the hard way, never ever dose h2o2 on lowered water. Always on full tank and after 50% water change.
