For future reference, does anything need to be done with those magnets prior to attachment? ("Black Rubber Coating" bodes poorly...)

And thanks for that link! Great prices and variety!

well, my rock cleaner doesn't need to be from gray PVC, but I am getting ready to install two Penductors and would like to use gray PVC for the risers. I found the pipe at US Plastic, but they dont have 90 deg slip x FMPT elbows...

I do see that McMaster has all kinds including Black schedule 40. I don't really need schedule 80. Which do you think would be best? Black or gray? The penductors are a VERY dark gray if not black.

Black will be less visible than dark gray IME. I used the dark gray in my MJ mods before to match the same gray that is on the MJ pump no other reason really.

a few quick snapshots of the new MJ kits and my tank. Oh yeah I just got a powder brown tang (for $25 ) to help with the grape caulerpa outbreak in my tank

Well, just a quick update:

I vacuumed more sand/algae out of the display today and water clarity is quite good. I swapped out all media yesterday and there's nothing like fresh carbon to kick it in gear. For those of you who are keeing count, I use 1.5 Black Diamond 3.65L canisters each time I fill the carbon chamber, and 1 full 795g PhosLock for the GFO chamber.

The brown algae is slowly receding and I am dosing 2 tblsp sugar every other day. So I think my response to this issue has been slow and methodical, but not radical and destructive, and that is allowing the situation to improve without killing off everything. One GBTA came back out today so that is a good sign as well.

Did you start to have water clarity problems when you first disrupted the sand bed? When I started to re-do everything in my tank and pulled out part of the sand bed and sucked out gallons of crud, my clarity suffered bad. Its been over a month now and it still has a tinge to the water, not crystal clear. It didn't help when I had the sump off line for a couple of weeks and no skimming. I have been running carbon.

not really. the water quality issue is not from vacuuming out the sand but from a nutriet/algal problem. Theway I vacuum doesn't really let anything get into the water column.

Maybe my algae bloom is doing it. With all the new water, new rock I have a ton of algae like setting up a new tank. I don't remember the water ever turning slightly green like this before.

green = algae bloom...you need lots of carbon, floss, and super skimming.

No. I figure I disrupted the system big time over the last couple of months. Removed all the rock to re-aquascape, removed part of the old sand bed, added new live rock... Also it ran without a sump or skimming for a couple of weeks when I ripped out the old fish room. When I brought the new sump on it added 180 gal of new salt water. Thats a lot of change. Lets see how the new skimmer does with it.

well, your skimmer is looking sweet. I am sure it and carbon will take care of the clarity issue.

Nice vid J.

A couple questions.


1. Are you draining SW (from water changes) from your sink to your septic system?

2. Is there a system of how you measured how much salt to add and at what level in the SW tote?

1. Yes.

2. No.

I just ppour in 1 bag for half a tub, and two bags for a full tub. Once it mixes for a day, then I check it and adjust if needed.
