Specioas are evil mofos. I've been working on this one for a month or so. Already bleached it a little, but at least it's still alive. If you see any speciosa locally, let me know!

This is a timeline of a mariculture piece I got from Clearwater about 5 months back. Post in thread 'Randy’s Flock o' Reef Tanks' https://www.bareefers.org/forum/threads/randy%E2%80%99s-flock-o-reef-tanks.32907/post-552858

Polycarbonate lid made from two pieces. If you want to get fancy, you could add a handle and use some weld-on to attach. I dremeled a hole on the backside for wiring. It's been used for about two years now. No warping.

Just find polycarbonate (do not used cast acrylic) from the scrap bin and cut to fit. Probably will cost you less than $5.

A week in copper is not long enough to get rid of velvet or ich. I suggest you visit humble fish to understand the QT procedures for ridding ich or velvet at humblefish. https://humble.fish/community/threads/copper-treatment.17/ Also check out...

Oh and here's why unions are so important in large tank or multi tank setups. If I had to replace that faulty bulkhead (the one at the top of the picture) while it was still installed on the tank, I don't think I could have done as easily as I did. I would have had to drain the whole tank...

150 Gallon Tank (Day 138) Some enabler mentioned a good deal on a tank to me and not surprisingly, I went and got it. I ended up adding an IM25 AIO tank to my 150 Gallon display tank. I plan to use this add on tank for bounce shrooms only. Plumbing this thing while the 150 was running was a...

While not CPEX true union ball valves, these have served me well over the years at a fraction of the cost. https://a.co/d/2a03BER

If you're going threaded into the bulkhead, make sure you use pipe dope/thread sealant and not Teflon tape. In my experience, Teflon tape will leak more often then not when used with PVC or you will get an excessive amount of salt creep. As a FYI, Teflon tape isn't technically supposed to be...

Then even more reason to have them higher. You can't move that tank easily because you can't set it down on the bottom of the tank because the drain pipes will be in the way. Also, I'd make things as serviceable as possible especially in a large tank. No idea when you might need to replace a...

Those unions are going to be a pain in the ass to service, if even at all possible. If it was me, I would have put the union closer to the external overflow box so I could reach over the tank with a ladder and added another union inside the cabinet right after entry into the cabinet. Where's...

I get that it will be a complete PITA to drain that tank, but if that salt creep came back after cleaning...... All I have to say is 300-350 gallons of water on your floor is probably a six figure house repair after water mitigation services deal with drying your house, getting rid of humidity...

Carx media will provide alk, ca and some trace elements. You can add Magnesium chips to the media to provide magnesium as well. pH effects of the acidic effluent can be managed by a secondary chamber with reactor media, co2 scrubber or dosing kalk. The cost probably doesn't balance out until...
