I did in the 75 with no ill effects. In the 125 I tried a couple of times for bubble algae but it didn't do anything so I gave up.Has anybody tried the in tank dosage of hydrogen peroxide at 1ml per 10 gallons for nuseince algae I just did like 3 hours of reading and many people who tried it say its 100% reef safe and kills alage. Other people who have not tried it said they would never do it as it would kill coral.
Some reports state it killed all pods, others say pod population exploded after dosing.
