Most of the shrimp died over a relatively short period for reasons unknown, I put the remainder into a community tank to see if a bigger environment that I knew was stable would help, but eventually all disappeared.

I've got Vals 8' long and some about 1.5" across using metracide at the recommended excel dose. I think like anything else an important consideration is to change slow -- start with low doses and build up slow, and don't change rapidly going forward after that. Val's don't like change. It...

I have a 25W Neo-Therm from Cobalt, which I'm quite happy with. Innocuous and fully submersible, and includes a temperature readout.

Delapool, I could probably put a blanket over it, nothing more structured, it's really crammed into a corner now beside some cabinets (the hoses run sideways to the tank 4' away). But... hmm... maybe a blanket. Never considered that, but I don't see a need for air circulation around it...

Interesting. Is this more like a sump, where it's open to the air on top? The canisters I've seen are sealed, water coming in via one tube and out by another, no air inside at all.

That's.... different. In this one, the pump is actually at the top. Until the media area fills and actually over-fills, the pump is dry. I don't think this one works the same way as what you have (nor does the Fluval).

I'm sorry, I thought a canister was by definition completely full if it didn't have air in it. Can you elaborate a bit on what "over full" means in this context, and how I might check?

Yeah, good flow, in fact after cleaning (it was pretty awful) the flow went way up, but no change in noise. If I stop the flow, I get a fair amount of clacking as you might expect, but this is more of a hum. Though since the rotation is synced with the 60 cycle current noise in the rotation...

Incidentally the change came over a period of about 9 months, slowly. It was not "break" where suddenly it was loud. It just got worse.

I have four SunSun HW404B filters, and one Fluval 306. I bought the Fluval first, and you can tell which ones I liked better. However. One of them... naturally the one in my office, is getting louder. Substantially louder -- from almost dead silent, to now being audible over my computer...

Random things: 12V power supply for four Current LED+ lights instead of using four bricks -- more efficient and likely will last longer as it has a fan if it gets too warm. This was an old PC power supply that would otherwise be thrown away. It also provides +5 for a Raspberri Pi computer to...

And safe to ignore (I killed several and have not seen more lately, but I suspect they are still there). Then I wonder what to look for to explain the lack of babies. The females are getting berried, seem to carry them to term (I haven't seen eyes as they tend to hide more, but have seen very...

I'm set with that from spot treating algae in a big tank: About $7 in parts with a bit of hot glue. The tube I used is stiff plastic I got at a LFS, the airline I used first is too hard to aim in a big tank while not getting your hands in the water (and in so stirring it).

That's good to know, I have plenty of Metracide. I have not used it in that tank for the few plants, but spot treatment sounds really easy. So you don't think these are my problem with no baby shrimp?

Small (30G) shrimp tank with about 10 red cherry shrimp. It is a fairly new setup. At the first shrimp's release of eggs (not sure if just before or just after, they were hiding) I decided I had too course of a filter cover and replaced it. Four or five small shrimp eventually showed up, the...
