O.K., I know I have went a bit off the DIY build subject so I have changed my ways for now and here is the latest progress report on the system mixed with a little more info about those fabulous short tail nurse sharks! LOL! The pictures are below so check them out!
I am close, I think anyways.....to getting a pair of the short tail nurse sharks from a shark importer within the next few weeks if all goes well. They will come from off the coast near Kenya, Africa. I won't lie... they are going to cost an insane amount of money but if I can get them to breed, that's a big if BTW as I would be the first or one of the first to produce a live pup of this species (in captivity) at present I don't think any one has hatched a pup yet. These S-T lay eggs unlike their two much larger cousin nurse sharks. A few others have had them lay eggs but as far as I know they have all been infertile or the fertile ones have yet to hatch but the efforts in breeding these sharks are still a new thing and they can typically live for well over thirty years in a tank. The female S-T nurse shark in Amsterdam (at one of their public aquarium(s)) has lived 33 years so far and is still swimming! Nice-!:yay:
The pictures below show some of the latest, and most likely some of the last, upgrades for the D.A. RKL controller system/setup. I now have a 24 hour lighting system with the lunar white LED module which I hope will encourage breeding but at any rate it will allow easy night viewing without having to turn back on any bright lights to check out the tank. They look really cool suspended that high above the tank in the dark and there are six pods with 2 LEDs in each pod and you can control the Pods (on/off) by sets of two pods at a time so you can adjust the area and brightness of the tank which is an added bonus I think! The only other thing/module I will add soon is another float switch for a third sump I am adding as a "precautionary overflow/power outage reserve tank" (That's a little catch phrase I came up with, LOL!), which will be plumbed just under the tank and it will be connected with bulkheads and when, not if (LOL!), the power goes out and that tall skimmer backwashes all of that water it will go into the reserve tank. When the power comes back on the switch senses the water level in the tank being elevated and of course the pump will cut on and pump the extra water back into the system. The reserve tank will hold an extra 30+ gallons or so. I will also be adding a large 100-150 gallon stock tank that will be plumbed into the system from the sumps for a shark nursery to raise the shark pups in but that may wait till I see some eggs first!:sad:
The other pictures show the larger DIY protein skimmer I just added. It has a 750 gallon venturi pump driving it, I may put an even better Sicce skimmer pump later on down the road but right now it is doing a good job! It is about 4.25 feet tall with a 4" base section that reduces to a 3" top section and the skimmer cup is removable of course and the top will come off as well. I designed this while "playing" in Home Depot the other day for about 20 minutes and then built it in about 20 more minutes. Very simple design. Yes, it is made of PVC but even the smaller PVC one I built was pulling a lot of skim with a smaller pump and with the PVC there is no light going into the tower which means no algae growth. The price tag was crazy cheap other than the pump which still the whole thing was under a $100. You can see I also added a Two Little Fishies Kalk Reactor 300 which is plumbed into the auto top-off pump so it will kinda dose whatever I put in it at the rate of evaporation, etc. The PH already stays high so I use it to dose some liquid vitamins and such right now.
I have a bundle of large Red Mangrove plants coming soon that will be added to the biological sump and I will run a plant light over the top of them and of course run the light counter opposite of the primary lights so the PH will hopefully be alittle more stable at night. It does not go way off but daytime PH is around 8.40-8.38 and PH at night is about 8.36-8.34 (give or take) all of this is monitored electronically by the D.A. PH probe, etc.
There is also a photo of my primitive screen covering, it's in two sections so it is easy to remove put back on and it just sits on top of the sides, real simple.
I'll keep you all posted on the Short tail nurse shark situation and any other new additions.
Take care.
