Hello fellow reefers!

I have a rather pressing problem occuring in my aquarium. Recently, some dark purple substances had grown on the live rocks. It appears sticky, and is spreading across the rocks. Its seems to affect the leather coral nearby. Any idea what is this? Is it harmful? and also what can I do to reduce it?? I'm not so sure if its algae or not, but it seems to be (to me at least) >.<

Remove those rock with red slime and brush

      WTS Tanks, Equipment

      Hey everyone, I've a set of many things to sell off as one set. The following are in this set: 1. Long fish tank, 90x30x30 - beautiful glass, well taken care of, no scratches 2. Standard fish tank, 60x45x45 - beautiful glass, as you can see, still with bottom and top cardboard covers. 3. Metal stand for the long tank - rusted by strong. Usable. Please note the width of this stand is 50, and the long tank's width is 30, so there's around 15 cm space. 4. Nano tank, well taken care of. Beautiful glass. (The gadgets in there all taken out, so just tank with it's back sump. 5. A baby tank 6. A bunch of stuff: - Tidal 35, Seachem filter - two oxygen pumps - plastic fish tank protein skimmer - portable fan - large wavemaker - 90x45 nice tank background poster - mini filters Basically what's in there + take. In the photos below, I've saved some pictures from when I purchaser them. These were all used for marine/saltwater fish - if you want to convert to others; simply wash (that's why I got these tanks, flexibility). I've used them for a year or less. Selling since these are in my office, and we have settled on one custom size. And we may be moving. Need to send these off. Would prefer someone to take everything, clear everything. Only $220 for everything. If I see anything else I don't want laying around, I'll also pass to you. Self-collection/self pick up. Location: Indus Road, ground floor. PM me if keen, cheers!e0774394470a15537f6187c32e4cb04f.avif sg-11134201-22100-a8sr3atpx6ivfe.avif
