I have a small tank (standard 60l) with a 30l sump in which I keep a couple of fish and some inverts. It has been running for about a year now without any major hassles, apart from a bit of algae. Since I don't have a protein skimmer in the system, this was to be expected and I managed to keep it under control through frequent water changes.
A few weeks ago I decided to build a small algae scrubber. It has been running 24/7 since then and it certainly helped keep most of the nuisance algae out of the DT. However, since installing the algae scrubber my pin cushion coral seems to be rather unhappy. Instead of opening up fully like it used to, it now sort of slumps on it side. I thought I would give it a week or two, but it does not seem to get any better.
I also seem to have lost my fire shrimp, but that may or may not be related to the algae scrubber. The boxing shrimp (small) and sexy shrimp still appear to be OK.
I tested for nitrates this morning and it seems like I am somewhere between 5-10ppm. Last water change was week before last (50%).
Any ideas or advice?
