I've noticed a slight drop in alkalinity. Say, from 1300 ppm to around 1250 ppm.

I'm making adjustments to bring it back up.

Thanks so much for the info!

Can I leave the shell halves misaligned and just leave the clam alone, or should I continue to try "helping" by manually aligning the shell?

Help! Squamosa hinge problem

OK, a couple of months ago my 4" squamosa clam was barely opening up. I noticed that something didn't seem right in that it looked like the two halves of the shell were misaligned somehow. I picked...

Just as a followup, I tested the efluent water again over the weekend. Tank nitrates are somewhere between 25 and 50 ppm, while the efluent nitrates are reading 10 ppm. Not quite zero yet, but...

Well, maybe I did the opposite of what I should have, but the smell did go away and it hasn't returned. The main reason I reduced the flow rate was because I was still reading nitrates in the...

Well, I tested for NO3 in the efluent a few days ago and it was still about the same as the main tank water (25 - 50 ppm).

But today I noticed the rotten egg smell. It got bad enough that the...

Nice job! This weekend is the 2-week mark for me, so I'm going to test as well. I just wonder if having the flow-rate issues along with having to take the unit apart slowed down the seeding...

Ya know, another idea might be to add 25 or 50 feet of 1/4" semi-rigid tubing (cheap and available at lowe's) between the powerhead and the sulfur canister.

Essentially you'd be putting a...

Glad to help out. ;-)

One thing I like about this 3-stage design is the carbon chamber. You don't see that on the commercial units, and it should help eliminate any 'rotten egg' smell.

Hi Greg,

Too high a flow rate will render part of the sulfur canister...

I think the flow-through canisters are a better way to go, as long as the flow is _slow_. But you're right, the original design doesn't use canisters.

Actually, it might be worth mixing the...

Oh, and as far as regretting cutting out the felt -- I wouldn't worry. Your flow is so slow that any particulates should settle instead of being forced up through the media. And, you still have the...

Hey, no problem, and thanks for sharing your diy design.

If I continue to have problems I'll just buy some refillable canisters from Buckeye.

That increased the flow initially, but over the last few...

Gen-X ozone generator?

I decided to try adding an ozone reactor to my 180 gal display tank (total system volume about 240 gallons if you include sump and refugium).

I built my own ozone reactor out of 4"...
