Seashells changing water parameters?
From the betta forum...Do seashells alter the water's hardness & PH?
Forgive my ignorance but, are they not the same material as snail shells?....If so,
I have some empty snail shells (from my betta's snack attacks) I will keep a better eye out
to remove during water changes.
If they don't alter it, can I just boil seashells I find on the beach to make them safe for the tank?
Thanks so much!!!
sea shells do alter ph and hardness...they release calcium carbonate into the water...those from the sea tend to do this at a much more rapid rate..
Good to know! Thanks! :)
I'll stick with fake ones since my water is already on the high side.
dont forget that you can add some aquarium safe drift wood wich will soften the water and lower PH slowly by releaseing tannic acids...wich can be benificiary to many fishes....
I have a 7 inch by 3 inch part of driftwood I've been meaning to use...I just was wondering how much it would soften the water?
Also, how long does the softening last?...Like, do I have to keep adding new driftwood every month, 6 months, year, or so to keep the same effect?
I have 7-8 betta tanks now, and another soon to be just guppy tank.
I'm in Tampa, Fl, and the tap water I use has a PH of about 8.2-8.4...If I leave it out
over night, it drops a bit though. I've never tested the hardness though, I use the API Master Test Kit which doesn't have that option, but I guess it's rather hard judging by the mineral build up on the faucets..Oregon tap water wasn't anywhere NEAR the same build up level.
I also add Aquarium Salt during water changes.
I have Betta Spa (indian Almond Leave extract) also, but it is pricey per gallon. (and is meant to lower Ph and hardness)
So my other question is...I have 5lbs of peat moss pellets for aquariums....How many pellets
should I add to the filter for a 3G's and 10G's to lower the PH & how do I do this without shocking them?
I'm good with water changes but I'd like softer water for them just in case.
Natural wood will lower pH as it releases tannins, but this is slow and unless you have a considerable number of chunks of wood it is unlikely to lower the pH by more than a few percentage points, say from 8.2 to 8 or maybe 7.8--but even this can be unlikely if something else is working opposite to increase the hardness--such as seashells that are increasing hardness and corresponding pH. The wood will last quite a while, but eventually it will rot and fall apart, though depending upon the wood that may take years.
Peat works the same, but much faster so it needs to be replenished regularly. This depends upon the hardness of the initial water; the harder it is, the more peat will be needed and the faster it will become exhausted and need replacement. I've never used peat, so I can't suggest how many, how often. First you should find out the hardness, GH (general hardness) and KH (carbonate hardness) as they are inter-related to pH. Your water supply people can tell you the hardness, and they may have a website with such information (what's in your water, useful information to know, it can surprise you). The higher the KH (carbonate hardness) the more it buffers the pH, preventing any lowering you might be attempting.
If you goal is to significantly soften the water and lower pH, I would consider a RO (reverse osmosis) unit; initially expensive, but long-term it pays for itself. This if you need/want softer water, and depending upon what extent.
Last comment: do not use salt in freshwater aquaria. I'll end with some information I prepared previously that will explain the effects of salt; as Betta are very soft acidic water fish, they have a suceptibility similar to characins.
Salt is detrimental to freshwater fish and plants in varying degrees. To understand why, we must understand what salt does in water.
