Lake Victoria PH/Hardness

Postby Duds1000 » Fri Mar 05, 2010 10:28 am

Hi
I live in a soft water area up here in Scotland and would like to know what other vic keepers are doing to keep the PH and hardness up in there Vic tanks. Is it better to use tufa rock and coral sand or use a epsom salt and bicarbonate of soda mix?

Better to use African cichlid salts as these contain all the trace elements that are present in the lake.

Ok thanks, so is the Epsom/bicarb soda mix just a cheap way of raising the PH and keeping the water hard? Will the cichlid salts buffer the water? or will this just put trace elements in the water? will i not still need some sort of buffer to get the PH and hardness up as I have soft water?

You still need to adjust the pH, but check what it is from the tap. I stay in Troon and our water is very soft , but with coral sand and ocean rock, my pH sat around 7.6 without adding anything except cichlid salts.

Seachem is a very good product but for me became too expensive, why do you feel you need to do anything to your water in the first place ? Of the 3 main lakes, Victoria has the softest being a bowl.
Some species like Astatotilapia latifasciata and Haplochromis sp."ruby green" are from surrounding bodies of water and can have parameters similar to riverines as some areas are covered by vast areas of swamp. These species i have found do not do well in hard water long term but a moderate ph of 7.6 will do.

The only reason i would add cichlids salts would be to stabalise the ph in very soft water, this would need using along side the ph buffer but use in moderation.

My water runs off Dartmoor and is rather soft but with coral gravel and rocks in a lot of tanks all i ever add is a little bi-carb.

hi thanks for the information, my water is very soft around here. I was going to use sand and rocks in my tank but not coral and tufa. Ph here is about 7 but would need some kind of buffer as the PH falls off very fast! The malawi/tang breeders around here use a Epsom/bi-carb mix. So if i just use coral sand and rocks I will have no problems with vics?

Hi Graham
To raise the ph / kh i use sodium bicarb gh use epsom salts but if your buying fish from a breeder / shop its a good idea to match there water if possible to start with
