CUC, RSR Screen Top Kit, Inkbird Temp Controller
Status of tank - very small diatom bloom (well timed with arrival of CUC), just a spot here and there on the sand and rock. Nitrates managed and not increasing (as measured before last water change) - think the NOPOX is working, kinda-sorta, maybe. Still early. Parameters are stable. Tunze skimmer has settled in very nicely. Fish are all doing well after a week in their new home.
CUC - purchased the following from
www.reefcleaners.org
Qty | Product Name |
| 2 | Blue Leg Hermit Crab |
| 5 | Dwarf Cerith |
| 5 | Empty Hermit Shells |
| 5 | Medium/Larger Empty Hermit Shells |
| 5 | Nerite Snail |
| 5 | Nassarius Vibex |
With shipping: $20.85 (shipping was more than the order - to be expected). Very satisfied with my order and with reefcleaners - they'll be my go to on CUC. Got way more than 5 dwarf cerith to boot. Love the look of the empty hermit shells in my tank. too.
Any thoughts on that being overload on CUC? Did I miss anything I need to have? I've seen every recommendation from 1 per gallon to 1 per fish. Best advice from numerous sources was to start smaller and add CUC as you add bio-load. Made sense to me. So far everyone is happy and healthy. I'll let you know if any starve, but I am feeding them a bit extra and I did wait until tank was 6 weeks old so thinking we're going to be just fine.
That's the CUC (and the remains of empty shells) dotting the landscape. You can see some diatoms on the rock and maybe a slight discoloration on the sand. If this is bad as "Ugly Phase" gets, I'll consider myself lucky....somehow, I doubt this is the worst.
As I mentioned previously, I had purchased the RSR screen top kit from
BRS (shout out to those guys for recommending a non-
BRS product simply because it's better - what a concept in today's business world). Went together fairly easily but if you'll allow a couple words of advice...
Get yourself a fairly decent (but still very reasonable) miter box (plastic one does fine), a decent hacksaw/blade (think I spent $12 on it) and a pair of clamps.
Those clamps made all the difference. Attach them close to either side of the line you want to cut and saw away. Blade only binds if the aluminum frame moves so make sure they're attached securely.
I tried to use what I had on hand....
And even with clamping to my workbench it was completely inadequate. I cut through the frame material alright...but that 15 degree angle wasn't exactly optimal. So out to the hardware store and back with the right tools for a very reasonable 30 bucks.
By the way...all my aquarium stand and accessory build work has been done on a Worx Pegasus Workbench. Recommend one highly - approx $100 and well worth it. I'm sure any name brand portable folding bench would be a big help...that's just the one I purchased - couldn't be happier and I've used it for everything else around here.
Here's the finished product.
The screen isn't perfect but it's much closer than I thought it would be. The only gap more than 1/4" is in front of the overflow box. The screen was just me using clamps to keep things tight and taking my time with the screen gasket tool. It's a tad loose in the back in one corner and I haven't tried any hair dryer heating action - anyone have any experience tightening up screen?
Oh, there is one slightly annoying thing about the RSR directions. The inches are in decimal format. For example: 17.01 inches. Helps to know that 1/16 = .0625. I don't think you need a 1/32 division, the tolerances just aren't in hundredths, especially when you're using a hacksaw in a miter box. I did keep an eye on which side of the pencil mark I made I wanted to cut on though....and measured everything two and three times. Even then I blew it once and cut a piece too long. There's enough extra that if you plan it ok, you can mess up once (maybe twice) and still come out ok....well at least I did. All in all a great product for even the most newbie DIY-er.
Updated 12/24/20: The Inkbird controller failed last month and I'm not longer recommending it. 18 months just isn't enough. Considering my heaters were only cycling 6-7 times a day, this should've lasted much longer. I'll post a write up in the thread in the next day or two. Still going with my idea of temperature ranges but going with an old school solution. Good news, it failed but because of my separate backup - temperature didn't go too low and the Apex notified me of the issue just like it was programmed to do (love having a monitor separate from control - read on for more on that. - Qm
Last update for today is the new Inkbird controller ITC-306T (the blue one). $29.99 on Amazon. I got it because adjusting those Jagers manually is a pain and this has the ability to set one temperature range (off and on) for day time and one temperature range for night. Which is important to me (see my post earlier on temperature goals and the below link).
I'm not convinced that expensive temp controllers are necessary as I've been using a Bayite for 5 years on my freshwater tank with no issues. Ask me that after I have a crash due to failure - but I have designed safety features in my heating system.
For one, I use the 2 75 watt Ehiems Jagers on the controller - one of which cannot over heat the tank with a "stuck on" failure. Plus, I have an AutoAqua Smart Temp Security controller to prevent overheating if the controller fails on (or the temp sensor fails low) and lastly I have the 100 watt Eheim Jager heater on a separate outlet set to 74 F to keep the tank from ever going out low on failure. The 100 watt heater alone is not enough alone to overheat the tank under normal household temperatures.
The controller allows 0.1 C of control band (although oddly only down to 1.0 degrees in Farenheit - go figure), but Celsius isn't a big deal for me at all to work in. There is no cooling function on the controller, but honestly, why would anyone put the fan (don't need a chiller where I am) that cools the tank due to a failure on the same controller that might have failed in the first place?
Here's my plan for maintaining daily and seasonal temperatures.
The yellow is what I'll be setting monthly. I'll have it laminated and keep in my stand so when my calendar reminder goes off, I can easily adjust. Takes about a minute to do on the controller. Yes, I know - Apex seasonal control will do the same thing and probably a tad smoother but so far...I haven't come close to considering that value prop yet on what I've spent.
For anyone's reference the best summary I found on why varying temps is a good thing (and I'm sure this is referenced often) is from Chris Jury. Although the first I read about this was a scientific paper on impacts of bleaching but I didn't capture the reference source - apologies. Not diving into the debate here - by all means do your own thing. Just explaining why I'm doing what I'm doing (at least for now - all this could change).
