Bad Hair Algae

Hair algae LOVES low Calcium and low Alkalinity. Considering you are using IO salt, and not supplementing, then it is very possible that your Cal/Alk levels are low. Calcium should be 400-425 ppm, and Alkalinity should be 8-10 dkh (err on the high side). Your low pH leads me to believe that your Alk may be low as well (see below).

When you do waterchanges do you siphon off as much detritus from the rocks and sandbed as possible? This can definately help lower the waste in the tank. Hair algae traps detritus in it (which is how it helps itself to grow), and using a turkey baster daily to blow any detritus out of the hair algae may help as well.

When you say you "presoak" your food, do you pour the water off, or do you just soak it in water and dump the whole thing in the tank? I would suggest you feed your fish at least once every second day. Twice a week is pretty tough on a digestive system (smaller fish) that is designed to constantly be eating.

How often do you clean your skimmer? How much skimmate do you get in the cup each week?

That's all I see provided the information you gave.



This is exactly what I was thinking. Low pH is often related (although not necessarily directly) to your Alkalinity level, so your low pH makes me suspect low Alkalinity. 7 dkh is not the high end - that is in fact the low end. Alk should be 6-12 dkh, with 8-10 dkh considered "normal". I keep my Alk as close to 10 dkh as I can. Many people who run ZEOvit keep their Alk in the 12-14 dkh range.

I believe the kits I am using are salifert. I am not testing for Calcium and Alk right now, I will have to run out and grab those kits. I'll grab some calc/alk additives as well and make sure those are in the correct range.

I do siphon everytime I do a waterchange, and baste the hair a few times daily into my skimmer.

When I presoak my food, I just pinch the frozen mysis in my fingers and run tap water through it to melt it and rinse away gunk from it.

I clean my skimmer every couple weeks, and only get around 1/8 of a cup a week. Seems really low to me.

I did a waterchange last night and ripped out as much hair algae as I could, and when I hooked my skimmer back up it was going crazy. The collection cup would overflow with bubbles in like 30 seconds. I turned it off and tried again this morning and it is still going nuts. Any ideas why it would be doing this?
