36 gallon bowfront aquarium with 10 gallon sump

30" Aquatic Life T5 fixture, 2 actinic (10hrs) and 2 daylight bulbs (6hrs)

8" from light fixture

DOC, no idea

Yes I skim, Prizm HOB surface skimmer

Yes I run carbon

No I do not run GFO

No freshwater dips

2 part Calcium/Alkalinity

I feed phytoplankton, cyclopese, rotifer and whatever the fish eat

I do a 3-5 gallon WC, (straight from the tap) every week using IO salt

Im curious if you know or measure your phosphates since you dont run GFO and youve had your crocea for nearly a year. Very nice!

Is it normal for derasa clams to go on walk as it started on a rock and jumped on to sand bed so removed rock but it just keeps moving itself on sand bed. Just wanted to know if it normal behaviour

I'm embarrassed to admit that my phosphates are basically off the chart. They are very high in my tap water but I'm guessing my clam and corals actually utilize them. Amazingly in the 8-10 years that I've been keeping reef creatures I've never had an algea bloom, just a little bubble algea which I siphon out with WCs.

Your clam is not happy and is looking for a more suitable location. If there is a spot in your tank with more light or perhaps less flow try sitting it there.

No need to be embarrasses!!! this is intersting info. Anyone thaat can keep a crocea for a year is doing something right!! keep it up!!! By the way, are you keeping Acropora's in this tank and if so how are they doing with the high phosphates??

Your tank looks awesome.

I've put wrong purchase date ment to be 22/12/13.

got it updated, thank you.

 

 

Since you mentioned the 1 year thing, I figured I'd post up a quick cell pic of how much growth my maxima has put on in 1 year. It's funny how you barely notice a change in size, yet they seem to have grown a ton! 6 levels of scutes total, but much further apart than what was achieved during aquaculture.

 

This maxima is likely the fastest growing one I've ever had, and the only clam I have kept on a skimmerless system. Possibly a correlation there.

 

Red line indicates the shell size when purchased.

Hey everyone. So after a few months away I'm back lurking on NR. Unfortunately, due to some life events I had to sell off my clam collection and actually my setup and downsize to a 7 gallon cube. I'm not quite sure what's up with the clams I sold to local members. I will hopefully be back in the clam game this summer when I get a larger tank.

Pics as promised :)

 

Please excuse my point and shoot quality pictures. When I got into reefing I had no idea that alongside skimmers and lighting, I also needed a fancy camera. ;)

 

Since taking the pic I'm seeing a little bit more extension so so far so good. I think it is looking great considering I had it shipping in yesterday morning. It actually had a nice aiptasia hitchhiker on the shell but I guess my new peppermint shrimp took care of that for me sometime last night. Don't mind the GHA in the background. I did a full rescape a couple weeks back and I have been getting hammered with the stuff. Fortunately my new Turbos are going to town.

Hey buddy, sorry you had to pass your clams out, but as we know life often gets in the way of our obsessions. THank you for the update, I will edit the list.

I got it from Liveaquaria. I'm getting plenty of extension now, well past the scutes.

 

I don't think I will need to do any feedings as my tank is somewhat dirty due to the recent scape and removal of LR. What should I watch out for in terms of figuring out if it's not getting enough "food"?
