crs dying off

Recommended Posts

smicko

Hi all. I have noticed over the last two weeks that I have been slowly losing my low grade crs. I have checked wp except tds (dont have a pen yet) and all good. I dont think its a molting issue as I watched my ss female molt the other night and she's going great guns. She also bred but ive only seen 2 babies.Tank has fluval stratum substrate and I add fluval shrimp liquid, it runs c02 at 1 bubble per 30 seconds and a t8 fluro grow light. I started with 10 a-c grade and 2 ss culls. I now habe 4 a-c and the 2 ss left (a pair awsome). I water change with conditioned aged tap water. Strange part is the low grades where bred in tap water and the ss in ro with salty shrimp but the ss are happy and breeding. Any help greatly appreciated as I dont want to lose more. Sorry for the long post, trying to include all info I can.

Cheers mick

Difficulty to assess due to the use of tap water, as the additives/inconsistency can create issues with no fault

of your own. I've noticed a drop of shrimplet survival with high TDS, so great if you can check this once you've receive your pen. If all you WP are fine, (double check your nitrates), suggest perhaps using some activated carbon in your filter and throw in a IAL. Do you add any mineral to your tank ? i.e. salty shrimp, mineral powder ... ?

Hi bb I thought about the tap water but figured it would kill all not just some. The only thing I add is the fluval shrimp which I thnk only raises gh when needed. I will def check tds when pen arrives ( thanks sqiggle for telling me where to get it). I havent got ial handy but I have heaps of bannana leaves so I might try that until I get some. I find it wierd that the higher grades are doing well and lower grades are dying, could they be a weaker strain? I will add some carbon today.

Cheers mick

I have dried banana leaves in my tank..not sure whether they work as well though. I can send you some IAL today, if you PM me your address.

I can get some ial tomorrow so I will hold off on the banana leaves. Thanks for the offer bb but I should be sweet.

Cheers mick

      Mine is a DIY Chiller, as you know a peltier has a hot side and cold side, for the cold side to stay cold, the hot side must be kept cold and with a heatsink and fan to cool it down. My DIY chiller has two sides and two water block. blue aluminum block with tube leading to the outlet of the canister filter and back to the tank to chill the tank water. copper block is to cool the hot side of the peltier, with copper block to the radiator/fan and a water pump looping. The problem is the tube from the water pump came off, apparently the plastic from the pump started to melt and the tube came off and the looping side had no water, so the copper water block stayed hot all the time with heat transferred to the cold side of the peltier also heating the water. since the copper takes time to cool down, most of the heat and the room hot temp had already heat the tank water to about 45 C.

      Try testing it again and see what you get or to confirm that the previous were right, especially the higher Ph reading is all I can recommend! If there is some explanation for the difference hopefully someone will reply and let you know, but I expect there won't actually be a difference if you do it again? Simon

      No that's not normal. But I don't know which tube in your loop had come off. Can you show us?   Yes that would have helped a bit, and at least give KMS more time to have found the issue by turning off the chiller. As I understand, kms has a peltier style chiller, and a tube of the pump had come off, which meant that hot water from the hot side of the peltier flowed back into the tank. So if the chiller was on the same temp controller, it would have turned off the chiller at around 26degC. The tank might have got warmer in his room, but it would have been at a much slower rate, and certainly would not have reached 45degC.

      I'm using the API master test kit with the dropper bottles. I was just very confused at how much more akaline the water was coming out of the filter compared to the water out in the open. I can't imagine how this fluctuating change in pH is going to be beneficial for my crs.

      What type of test are you doing strip or drip? I use drip tests and always ignore the first attempt as no matter how well I clean and keep the test set it is often way out of line. Las time first test was Ph8, second test Ph6. Sometimes first attempt looks ok so I have no idea what is going on????? If you just tried once it may be worth testing again? Simon
