View Full Version : I think I found the problem that I think caused the algae bloom

I started the mag treatment and it did not work I skimmed the tank with a skimmer rated for 125 gallons (my tanks 36 gallon) everyday emptied the cup which was half full tank never cleaned up yet lost almost all my zoas from the hair algae or bryopsis choking them out or not letting any light in (im pissed had some nice zoas Hawaiian jokers tubbs ect)I think it is from the death of 2 starfish in my tank (which I think was caused by the high mag dont know) also I think it may be contributed to the change of bulbs (went from 10k to 12 or 14 k gotta look) which do you think the extra nitrates and phos from decaying starfish or the extra lighting output now I am saving what I can (a few zoas hammer and frogspawn monti cap) the rest is going in a 10 gallon to try to save or just throw out if I cant any opinions are welcome thanks John

water changes, Phosphate reactor, kill the lights for a while, and if all doesn't work, (borrow) a sea slug !

i hate bryopsis. i have the same issue.
it is quite possible the decay of two starfish caused a nutrient spike. I had two sea cukes and I am pretty sure they are now just in "reef heaven".
btw - what kind of sea stars? bristle star/serpent stars are pretty good at hiding.
If they were true sea stars - a 36g isn't quite enough to sustain them supposedly.

The death of the starfish caused a nutrient spike of nitrate not magnesium. The change in bulb spectrum has nothing to do with water chemistry. 36 gallons not a big volume of water to handle the death of livestock.
Are you using RO water for your water changes? How many fish are in the tank & what are feeding them?

feeding corals and fish coral food and a mix of brine mysis starfish 1 was black and white with star pattern on back the other was a bristle I know mag didnt cause bloom I think it killed the starfish and then the decaying starfish caused a spike and the extra light made the algae or byoprsis grow more intense

That makes more sense. Starfish are very sensitive to fluctuations in water chemistry. Rinsing the frozen foods in ro water and discarding the water will help lower some of the unwanted nutrients when feeding. Test your make up water to make sure you're not adding nutrients to our tank during water changes.
