gillznglass Posted September 22, 2015 Report Share Posted September 22, 2015 If anyone may have an idea of what is going on I would appreciate the help. Today's water parameters tested 9/22/15 at 10 am Ammonia 0 Nitrite 0 Nitrate 0 PH 7.4 Temp 76 GH 8 KH 3 TDS 198 Copper 0 These parameters have tested that way for 2 months. Other water parameters 10% Well water, 90% RO. Well water for KH. RO system 150gpd at 2 TDS RO remineralized with Seachem equilibrium System parameters 8 20 longs on sump system with a slow trickle refugium. Total water volume 210 gallons Water changes 20 gallons per week on average 6000K 40 watt full spectrum 4' florescent lights 10" above the surface one light per 2 20 Longs Filter media used Kaldness K1 moving bed media fluidized with 2 air pumps 2 stage Filter Floss Seachem Purigen Many Live plants 20 Long Refugium packed with live plants with Finnex Ray 2 Lighting, Flow set at apx. 20 gallons per hour Today added 250ml Seachem matrix carbon What is happening I have had some random shrimp deaths due to what I believed were due to hydra in the tank. I was also concerned hydra would harm the fry, performed the treatment described here. I have seen copepods and a few detritus worms in the system. http://www.planetinverts.com/killing_planaria_and_hydra.html I calculated the dosage of safe guard dewormer which is what a veterinarian recommended I use. It is 25 gram paste, at 10%, 100 mg/g. I used 1/4 teaspoon in the whole set up @ approximately 2.1cc. or .1 gram per gallon as recommended if my math is right. It may not be but the specs of the med are above. I waited 1 1/2 days. The hydra were dead. Then performed a 90 gallon water change to help rid the system of the meds. The Purigen was removed during the treatment and returned after the water change. I just got some Seachem matrix carbon and added it to the sump this morning since carbon is effective at removing meds. After I used dewomer, which was about 5 days ago, I have lost at least 4 adult shrimp 2 bloody Mary, 2 tangerine tigers, that I can recall. It appears to me is most of the adult population is not visible in the tanks. They appear to be gone. So could this be a result of miscalculating dosage? I have included my water parameters for the random deaths occurring before the treatment of the med, just in case they may not be ideal for what I have. They do breed quite well, but I have been losing fry to my filter system which is currently being addressed. Refer to this thread if you want to know what that is all about. There may be some information there worth noting. We feed shrimp king food every other day. Here is a photo of the shrimp that i found dead this morning. Here is a photo of what appears to be healthy shrimp taking this morning as well. I have not seen any light colored shrimp or ones that look unhealthy. They just die for what reason I can not speculate. They also molt well. I have only lost one I could figure due to a bad molt before I adjusted to the water parameters with RO remineralization. Was shooting for around 200 tds and 2 KH for PH stability. 2 days ago I added 4 level scoops of Bacter AE to the sump to up the bio film. (Bacter AE is new to the system and is the first time it has been used) I added some Friz Zyme 7 to make sure the nitrosomonas and nitrobacter were in check, just in case the fenbendazole had any effect on the BB. I know it is unusual to have 0 Nitrates but I assure you the system was fully cycled with the fish less cycle method and Friz zyme 7, long before the introduction of livestock. All I can say here is K1, live plants, and purigen, really do the job. Nitrates even test 0 with no water changes for 2 weeks. If there is any more information I can provide I have detailed logs of water parameters, shrimp deaths, fry born and many other notes and dates for each tank. We have Neo's, OEBT's, and other tigers all in the same system. As far as the well water is concerned, it has not been tested for anything other than ammonia 0, nitrates 5 to 20ppm on random tests, nitrite 0 and PH fluctuations from 7.4 to 8.9, affected by rainwater I suppose. We have not had it tested for pathogens but we do drink it, and it is very clear even though it is liquid rock. The TDS of the well water is 321 as of today, but I have seen it higher. On rare occasion I will gravel vac a tank that may need it, but water changes are performed by opening a drain valve in the system and pumping water in from a 110 gallon water tank where the well water is mixed with RO, and the equilibrium is added and mixed. I mix the equilibrium recirculating the water with a 1 HP transfer pump shortly before I do water changes. The pump is plumed to both recirculate the water back to the water tank and send water to the aquariums. The equilibrium is mixed in a shaker cup with RO water before pouring it into the reserve system. I have a power head with an air pump circulating the water at all times and heaters to bring the water temp to 77 degrees so there will be no temperature shocks when doing water changes. I use this tank for all the aquariums I have some of which have a number of very healthy fish. If anyone has any ideas on what I may be doing wrong please chime in.
