Have been busy with real life lately, but getting back to thread this weekend - think I will do the good news/ bad news thing.
Good news= The Male trigger is doing well. Still very shy, but has good color again, and eats like a pig. The corals that were starting to brown out and die when they were in the temporary housing 75 gallon ( now the refugium) are coloring back up and seem much happier. All fish transferred well and picked up some new fish from people moving or getting out in our area. So now have 4 percular clowns ( one that is nearly black) and all are getting along so far. Picked up a very nice coral beauty Angel and he and the pigmy Angel seems to be OK with each other so far. Pics coming
Bad news _ well not really bad- but the main system needs some "tweaking" = had several power outages 2 nights ago and I miscalculated on the consequences of that situation= water draining from the main floor display via return and drain plumbing down into the sump/ refugium has a greater volume than anticipated. I believe this is due to the Reeflo Barracuda pump not being on the floor in the basement- but 30 inches off the floor- so it is sending more water up into the display than I had figured because of the decrease in Head pressure. Also, because the sump is on a stand, that is on a counter top - there is less "drop" between the external overflow box and the end of the pipe draining into the sump = less gravitional force on the siphon coming thru the drain - so it pulls less water out of the external overflow box. Therefore, the volume the Reeflo is pumping is too much for the one 1 inch full siphon drain that I had figured would handle all the water being pumped into the display from the basement. So, I have had to use both 1 inch drains and dial down one of them to create a super quiet system. However, this leaves only the one 1.5 inch drain as a backup/emergency. Also, because there are now 2 x 1 inch drains with water in the pipes rather than the originally planned 1 full siphon drain with just a trickle into the 2nd 1 inch drain - when a power outage occurs there is more water int he plumbing = more water drains down into the basement part of the system and it overflows the 75 gallon refugium. I have and emergency overflow out of the refugium - so I did not still water all over the floor. However, the 10 gallon of water that goes into the emergency area must be put back into the system when the power comes back on - otherwise the Reeflo pump starts "sucking air".
Fix Options:
It is possible the situation could be fixed by reducing the volume of water being pumped up into the display by the Reeflo pump in the basement - thus allows only one 1 inch drain to handle nearly all the water flow and therefore reduce the volume of water that is in the plumbing that will flush down into the refugium. I can think of two ways to do this. : by either using the Gate valve on the return plumbing after the reeflo pump or by re-plumbing it and putting it on the floor and crease more head pressure. I have heard that the main issue with Reeflo pumps is the seals in the pump - so putting more pressure on it by using a gate valve seems unwise. Re-plumbing the pump may work- but not positively - and it will also be a pain in the backside, and when ever I want to do any maintanence it would require me being on my hands and knees = NOT unless absolutely necessary.
Another way to fix this is to lower the water level of the 75 gallon refugium tank to allow the extra volume of water that "flushes" down into it when there is no power or the pump gets shut off for maintenance or for feedings. This entails the removal of the last baffle which will then allow me to reduce the entire tank volume when the system is running and still provide full water to the return Reeflo pump.
If anybody has opinions on this - please chime in. Looks like my best option will be draining the 75 gallon refugium tank and try to get the last baffle out without damaging other baffles.
