Oh and you can see the Tunzes on the Wavysea's have been taken out. I had been leaning toward removing them for a while on account of a few reasons:
1) They sat way too far into the tank because of the Eurobracing. Apart from the obvious visual nuisance of two outboard motors hanging into the tank almost 8" off the back wall, it was ruining the scale of the tank as well. It made the tank feel really small and well .. while it's far from a big tank by many standards, it is the biggest tank I will ever attempt so long as I live in this house. (Well, ok, never say never, I suppose ... but realistically the odds of that ever happening are very slim.) I totally resented that they made the tank seem small.
2) Sand. I have sand after all. In the beginning I totally intended on going BB with this tank. But after putting the rock in, the very rough silicone edges on th bottom panel were visually disjarring so I elected to go with sand. And "lots of flow" and "lots of sand" never seem to work well together. With both wavysea combos on the back, the front half of the tank would lose all sand. So I tried moving one to the front to offset the one on the back, and this posed a few challenges, notably, it interfered with the t5's on that side of the light rack, and it had to work around the Calfo manifold. In the end I bolted the wavysea to the wall and then this transferred pump noise into the wall. The wall resonated with the humming of a running Tunze. Not offensively so, but it did take away from the goal of not wanting to hear the tank noise at all on the display side. And then after all that was all said and done, it didn't fix the shifting sand issue. Instead it created a trench in the front of sand-free area, and a second one in the back of the tank.
The final straw was this - found this on Christmas Eve:
After moving the one Tunze to the front, apparently the wire had a constant wiggle in one spot and the insulation eventually gave way. I was watching the Tunze sweep back and forth and noticed that at the right setpoint, it would turn off and on. So yeah, awesome, I killed another Tunze. Starting to wonder if Tunze is a 4 letter word in German..
So my plan right now is to switch two of the outlets on the Calfo manifold over to Wavysea's. Figure I have them and might as well still use them.
