Drainpipe question:
The durso style drainpipes that are placed in overflows are to reduce noise, correct? They do so by raising the water level before it flows out of the tank rather than having it crash 12 or so inches down to wherever the hole/bulkhead is.
The question is, for the drainpipes that are curved in the shape of an upside-down 'U,' is there a siphon right there that needs to get going? If so, does anyone have redundant backups to make sure that siphon never breaks?
Pipefish question:
I have a 29 gallon with no skimmer. I do water changes usually once every three weeks, and I haven't tested for a month or so. I have a GBTA, several softies (devil's hand, xenia, kenya tree, mushrooms, zoanthids, ricordeas) and a sizeable frogspawn frag that are all doing very well. I have a coral beauty, a clown (TR true perc), and a green chromis, as well as one peppermint shrimp.
I had a pipefish that was lived fine for about two months, and then disappeared completely. He seemed to be eating from the copious amounts of pods on the rocks and glass, so I never worried about it. Now that he's completely disappeared and everything else is fine, I have to wonder what's going on or how he might have died. Incidentally, he was the last guy in the tank. I tested the Ammonia, nitrite, nitrate, ph, calcium and alkalinity when I put him in and while I don't recall the calcium and alk results, everything else was either zero or within operating parameters. Any ideas?
Thanks. :D
