Ratio of water to algae

[hydride]

Hi,

I’d like to expand one of my tanks, a very small 0.25gal mostly enclosed jar with only two shrimp. I’m planning on increasing it to closer to 0.75gal with still only the two shrimp. Besides the water, what else should I add?

I recall being told that there can’t be too much calcium carbonate? I’d like to match pH as well as I can, but don’t know how much is required for a quantity of water.

What about algae? All I have in there is the filamentous algae from an ecosphere. Does more water need more algae even if there are only a couple shrimp? The water is from a different tank so it’s already cycled and whatnot. I’ll be drip acclimating over the next few weeks for minimal disturbance of the tank’s inhabitants. I was considering adding a small amount of the petshrimp macroalgae, but if it’s not necessary, I’d like to leave the tank as similar as possible to reduce stress from changes.

Thank you so much! This forum is the best.

The forums have now moved to Github Discussions. Head over there to discuss chipKIT.Hi! If you are planning to increase your tank to 0.75 gallon and leave only two shrimps, you will need to add a filter and water heater to create a comfortable environment for the shrimps. Regarding calcium carbonate, it can increase water hardness and pH. It is advisable to find out what the optimal pH is for your shrimp and adjust the water parameters accordingly. As for algae, a small amount of microalgae can help maintain water quality, but it is not necessary. If you decide to add macroalgae, make sure it is safe for your shrimp. In general, when you add more water to your tank, make sure that you have enough room for the shrimp and that they can move around freely. It is advisable to avoid overcrowding the aquarium and give enough room for the inhabitants to live. Good luck developing your aquarium!
