Shrimp water changing method discussion

Recommended Posts

Do you know whats in the mineral mix? If plants are using it, some would have to be fertiliser?

Do you run high densities/numbers of shrimp? If you do, it may explain why there is no build up, as i bet the shrimp would be using it up. It has a lot of similarities with how marine keepers have to supplement their water to keep up with the growth of corals, even in massive aquaria.

yes i know whats in the mineral mix :) no fertilizer mate!

there are a few shrimp in the system lol.

RO water or clean rain water is best to use with the saltyshrimp bee shrimp mineral GH+ :)

what do you want the water for then? most aquarium shops that sell marine fish have RO water for sale.

He means you need salty shrimp minerals ;)

Im serious you do :stupid:

you can not use RO/rain water for shrimp with out adding minerals back to the water. the shrimp will die.

if your using tap water just be sure to use a De-chlorination product first.

so does tap water still contain the minerals?

i shall get some saltyshrimp latter down the track when i get more serious:D

Yea, tap contains minerals, RO, Distilled and Rainwwater are stripped of these minerals hence people add back minerals through tap water or a mineral supplement like Saltyshrimp. Saltyshrimp is actually pretty cheap at $35 for about 1500L of water ;)

Nice Dean, certainly makes alot of sense about not doing water changes, and top ups with minerals, now i have a better idea of your system. Probably more prone to increasing tds in a smaller tank.

This interests me alot as I'm doing my PhD on sea urchin aquaculture; the way in which sea urchins strip seawater of calcium carbonate, particularly in the high densities suitable for aquaculture, shares some similarilities with how shrmp in our tanks use minerals from the water to grow their skeleton.

i would have to agree about smaller tanks and the need for small water changes sometimes. but i dont have any so can not comment with 100% certainty.my smallest tank is a 4x2x2 and it has not had a water change for about a year now. i just do top ups but it also doesn't have the mineral additives ads its a tap water tank. i use rain water for 4 top ups and tap for 1 and do this always. the PhD sound like you would have a much better understanding of this than most. i am only speaking from experience with my tanks/system and as we all know with shrimp keeping, what works for one person doesn't always work for another.

Your smallest tank is twice the size of my Big tank!!

Dayum, i need a 6x2 lol

im adding half spring water and half tap water to add the minerals back into the system, sound good?

I use ro water for top ups (evaporation ) and if i want to lower my tds i use ro and take a bit of tankwater out .water change rare but if i do i remineralize the water with mosura mineral plus to the same tds or lower by 10-20 points

As i top up i allways do this slowly with airline and clamp ,to drip in slowly .I just got some bee shrimp mineral from Dean and will give it a go

I always say keeping aquariums is more art than science. I bet even if i took over looking after someone elses tank/system, doing the same things they do, that i wouldn't be anywhere near as successful as they are. All the little tweaks that one can do knowing their own tank/system makes a huge difference.

Oh and if you are interested in some of the work i do with sea urchins, my first paper can be found here

      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.
    • sdlTBfanUK
      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
