i returned from my 4 week adventure delighted to see all of my corals still thriving. I have new mushroom babies, new round growths on the acan and it has adjusted and returned to its original beautiful color...everything looks healthy. But...I have something that looks like super fine algae filament over ever surface. It wasn't here when I left, but it has fully developed over the last few weeks. Is it a harmless algae? Bacteria? It's very light opaque in color and seems to be nearly uniform in height over all surfaces.
They both came up zero yesterday evening. I have a bag of phosguard I could add if that might help. Turbo snails seemed to think it's yummy.
No. Calcium levels are good too. The Halimeda is light in color because it had been in darkness a few hours before I switched on the lights to take the picture. It becomes a nice shade of green during the day. And that filament is on every rock surface, on the snails, literally everywhere.
I could never get Salifert to register anything but zero even when my PO4 was over 0.08. I would go ahead and run the phosguard.
Wow. Less than 48 hours with phosguard, and it has nearly disappeared. So I must have had phosphates. What test do you use?
I use the Hanna ULR photometer. Pretty reliable, but phosphate is one of the harder things to test for especially in the very low ranges we need to keep it (5-15 ppb)
