Not sure yet. YES I want a reef BAD! I will have to see if the budget allows.
Congratulations, Henry. A new home and a new tank on the way, right?
Yay, I'm back! Nice to see some of the normal posters too! Marc, your tank looks awesome already! And, MidNight ya kitchen looks awesome too! Waiting for more pics of both! I'm glad to be back though, I am starting to get the reef itch. I moving into a home this weekend, sold my condo in a week and a half. Woot! I have been VERY busy with grad school. That is why I haven't been here. Hopefully I can make some time. I can't wait to catch up on everyones reef.
Just to clarify, I meant that I tested my meter against the same photometer the GA Aquarium uses with the same water sample to see if they matched. I didn't care about testing my specific sample with their meter. I just wanted to see how both meters matched up with a control sample.<br><br>I haven't tested my premix SW in a very long time. I was resigned to the fact there was PO4 in it. Well, it just so happens I recently changed all the filters in my RODI except for the membrane. I tested my premix SW and it tested 0.00. <br><br>To answer your other question, I keep my PO4 between .03-.05. It's .05 right now. I do this by design because I find so much color is lost in my acros when I drop levels close to 0.00. I'm actually about to drop them lower for a while. I'm going to try increasing the "blue" lighting period time and shorten the 14k lighting time in an attempt to help with color. I run a MH/LED hybrid with 800w of MH and ~330w of LED. I run 6 on and 6 off. I'm cutting out the MH completely in one of the photo periods and using a 22k+ spectrum in it's place. It's more in depth than I'm going into here but too lazy to type ALL the details out. I'm going to keep checking my water periodically though. I'm very relieved to see a 0.00 flash up. I usually test twice if 0.00 shows. Did not do that today.
This one looks close to what I have, but it's 1.5" slip/slip: http://www.aquaticeco.com/subcategor...g-Check-Valves Smaller version, but not clear: http://www.aquaticeco.com/subcategor...0-7C85A2F1CAF3 The one I've had in my inventory for a long long time, waiting for the day I was going to set this up. I had different configurations running through my mind, but finally opted to go this route as pictured. I'll probably wrap something around it (like a coozy?) to avoid algae growth within from the light shining on it.
Marc, I love the idea of the check valve. I have anti siphon holes on my current plumbing and they don't always stop the water at the convenient level. Do you have a link or a part number to order one? I'm in the process of building my 300g and definitely want to incorporate that into the plumbing.
Congrats for blog #500 and for restarting the 400g! Initial pictures look nice, post more
glad to see you used the check valve, and even more excited to see it works great!!
Yeah, this is definitely a better design. I tried to find a previous picture to post them side by side for comparison, but it didn't really seem to have the same visual impact picture-wise, to me anyway. In person, it's way better.
I have been so busy remodeling our house that I have not posted anything. that design looks better than the old one. less materials in the way of you and the lights. I copied your old design and it tends to block a lot of light from the right MH. I may have to make this adjustment.
Well, I'd like to know what your final decision was. Your tank looks great, what is your current PO4 measurement? So the meter at the Georgia Aquarium also measured RO and RO/DI at higher than 0 readings? I've never doubted my Salifert test kits. Zero was clear liquid, any hint of blue was PO4. Depending on how blue it was, the worse the number.
Dang Marc, I wish I saw this thread before you were here earlier this week. I would have had you up till 5am talking about it! I posted an almost identical thread/problem in my forum early this year without any answers. I was having PO4 issues and couldn't understand why given my filtration/equipment and WC schedule. I then tested water from my RODI with almost identical numbers as you did with my Hanna Bench top. (Not the pocket checker) If I remember correctly my RODI was testing around .07-.10. I questioned the checker and tested against someone else's Hanna bench top with identical numbers. Then, I took it to be tested against a very fancy photometer that can test for darn near everything. (I think it's around $2-3k) Same one the Georgia Aquarium uses. My Hanna was still dead on with a matching reading. I will rekindle my efforts to solve this issue. I didn't get much feedback from others because it seemed no one else ever tested their RO water. And, fwiw, I love Salifert test kits for everything BUT PO4 tests. I found it to be so far off it's laughable.
amazing! and thanks also for the teaser pic :P
What water pressure is going into your RODI unit from the source. I think mine is around 45 psi. Just wondering if faster or slower PSI would matter..... I guess it is similar to what you are talking about, just a different way to measure it maybe?
They are pretty much going up at the same time but I'll be doing blog entries about specific topics rather than a mash-up of stuff.
that looks very nice, can't wait to see more from this tank and the future masterpiece
I bought my plumbing from Savko and FlexPVC.com - it costs way more, but looks so nice.
Technically, rubber to PVC, although I put a bead of silicone between the acrylic box and the PVC base. The rubber flat washer/gasket created a small gap and I felt the silicone could help support the box and fill that tiny void with rubber glue over time.
melev, awesome cube. When I upgrade from my 75 to a 180 I also hope to get a 60 cube either plugged in to the 180 or not, but love the cube look and think its perfect in a 60 gallon. Where do you get that black PVC, like tubing and those 90 degree pieces, etc...? Or do you simply paint some PVC 40 or 80? If so, what type of paint? Thanks and love the detailed updates!
the parts you were silconing together were acrylic or pvc?
