BTW Lance I was looking at BRS and noticed they have 4" 200 micron bags, both felt and mesh - they say the mesh clog less easily so I might give those a whirl, you might want to check them out too?

Thanks Tony. I'll definitely give them a try. I order from BRS quite regularly.

Precipitate. How come? Help!

Lately I've been getting a lot of precipitate build-up in the return pump, (Mag 7). The PH's in the DT have no build-up at all. I just tested and the params are: Ca: 410; Alk: 7; Mg: 1290; pH: 8.0 These numbers stay quite constant from week to week. I use the two-part from BRS and dose via 2x Drew's Dosers. Both dosers drip into the return section of the sump; calcium in the morning and alkalinity in the evening. Is it possible that there is not enough water movement in the sump? I estimate flow through the sump at about 280 GPH. Any ideas?

P.S. I'm using exactly the same set up on the 225g with no problems, so it's not a problem with the two-part mix.

I was having the same problem, bumped the mag level up to 1400 and changed the one dosing line to the overflow so it mixed better, solved it for me.

Thanks Dave. I'll try upping the Mg. I used to keep it at about 1350 but I found the SPS does better with it a little lower. I might try a bigger pump for the return and get a little more flow through the sump as well.

Man-eating Trigger!

Thinned a few corals in the 90g this morning and was mounting these frags in the 225 when suddenly Bubba decided he wanted to sample a little human flesh. Bastard nailed my pinkie finger and drew blood! This comes as a surprise as I have held him in my hand many times. Maybe my pinkie was sticking out from my hand and looked like a nice fat worm? Christ, it's bad enough having a blood-thirsty mama Fire Clown; now I have to contend with a 6" Trigger with a mouth full of big teeth. I just hope the Tuskfish never wants to sample me, those fangs could do some serious damage. It's a sad state of affairs when one has to don Kevlar to work in his tank.

My mom used to put those kinda books up high on the shelves when we were kids so we didn't get corrupted and stuffs. Glad home life is exciting buddy =)

Ouch! My triggers like to bite fingers too, but only when Doug sticks his fingers in the tank and wiggles them around :lol:

Hehe. Brett, I swear you could find smut in a nursery rhyme!

Laurie, I think that's what I must have been doing: Wiggling my fingers.
