๐๏ธ Build Thread
In Progress

Shipment arrived. Tank sump and stand.




+1
Unboxing. Everything appear unharmed from shipping.

Stand built, began leveling.
Reinforced crawlspace floor joist with jackpost x 4. Already in a great spot structurally, but more peace of mind.


Added pond liner to sump area for water proofing and moved in the sump.

Received the first batch of equipment.



Batch of marco rock was delivered.


Tank moved into place. Never want to do this again.




+1
Begin aquascaping and releveling tank with weight.
Washed the dry sand, 140lbs cleaned and added to tank. Aragonite. Have another two bags in reserve.


Spent the weekend making water. The old RODI system and booster pump is pretty slow for this size tank. Need to consider other water storage options going forward.
Not happy with the MP40. Our glass is at the max spec for an MP40, but still in spec (19mm). However, we could not keep the dry and wet side from separating due to what seems to be weak magnets. Without a gaudy cable holder, the dry side will fall off during speed changes. Why do these not also include suction? Idk.
Ordered two Jebao DMP-55. Fraction of the price of the MP-40 and has suction cups.

Began dosing ammonia and Dr. Tim's bacteria. Cycling in progress. Added two spare live rocks from other display.


I think the Jebao pumps got it right with the suction cups, especially for those of us near the limit of glass thickness.

More equipment arrived.


Initial light fitment. 4th light in on the current 40G but will move over soon.


Began moving some equipment over. InkBird, ph probes, etc. Lots of cable management needed here, but I want to get the other tank moved over first because I will be adding a light from that tank.

Starting to get some nitrite.
