Hello all,

I have a few large zoo colonies which I love and have grown from small frags. Recently, some type of green hair algae has started to grow in between the zoos. It will chocke them of light if I dont prune by hand every week.

I have tried phosphate sponge, PO4 minus, astrea snails, turbo snails, troncus snails, margarita snails, and my nitrates are near 0.

Has this happened to anyone and what have you done to resolve it? Even tricks to remove algae other than my fingers would be appreciated.

Check your magnesium levels and if they are low try elevating them to the upper end (1600 ppm), I have had positive results with this with types of HA as have others. Do search on RC about it for more info.
