i do a 4:1 ratio for 5 minutes on my zoas and it works amazing.
Do you do a 4:1 ratio on other corals?
I've been testing with different amounts of FRESH h2o2 in tank water for 5 minute dips. here are my findings so far:
160 mL of H2o2 per gallon: the majority of hair algae falls off within 24 hours, corals are fine, but algae comes back.
120 mL of H2o2 per gallon: the majority of hair algae falls off within48 hours, corals are fine, but algae comes back.
80 mL of h202 per gallon: hair algae seems unaffected. no difference.
I've tested all three of these different ratios on zoas/palys, florida mushrooms, toadstool & kenya tree soft corals, a lobo, and my snails & hermit crabs, all for a period of 5 minutes. All organisms seem fine 24 hours after dipping.
I've been vacuuming the crushed coral substrate for this hair algae, draining the crushed coral, and then putting in an h2o2 solution 5 minute periods while i pick out the hair algae clumps, and then I return the crushed coral back into the tank.
Last night i upped the ratio and when i vacuumed the substrate, i added a 3:1 ratio (3 parts salt water, 1 part h2o2) for 5 minutes and then returned the crushed coral to the tank. I'm wondering what strength is too strong for hermit crabs, snails, and corals.
