New Tank 48" x 30" x 20"

[MadScientist]

Thanks, Bro. Still far from it. Parameters off the charts at the moment. Trying to change water gradually to bring them back to normal. Any good and cheap salt for FOWL tanks to recommend? The usual reef salt has too much MG n Ca for me. lol!

Instant ocean

[ming69]

I need a salt mix which has the lowest Mg. So far, tried to look for reviews with specs seems kinda hard to find.

Have u tried to measure the mg for instant ocean, MadScientist?

[MadScientist]

Many people at reef central tested it. Salt mix results often differs.

Cheaper brands tend to have lower mg levels

[ming69]

found it! Thanks for the tip.

Why would you need low ca mg for fowr?

[ming69]

fowl salt usually low on the ca n mg, at least, that's what i was told.

[MadScientist]

Not amazing low anyway. Just slightly? Ca for reef salt is 1300-1400+, normal salt would be 1100-1300+. A little more ca and mg won't hurt the fish. It's good for you as you have the buffer to keep snails and shrimps.

The reason why fowl salt is lower in ca and mg is to reduce cost?

[ming69]

Maybe. Guess I'll be trying out Brightwell for a while to bring down my Mg.

[MadScientist]

Not a wise move to reduce mg by too much. Mg helps to prevent ca precipitation on surface. Too little mg and a lot of you ca will precipitate out onto you pipings and impellers.

Low mg also makes your alkalinity hard to maintain

[ming69]

My problem is High mg, High ca and low KH...... Think I need to switch off my CR for some time to let them lower by themselves. 5% WC every other day doesn't seems to make much difference. Sianz....

[MadScientist]

5% does nothing much to reset buffering system. Try to use sodium bicarbonate to increase alkalinity? Better to monitor salinity while doing that.

Fish are not fussy in regards to such parameters. My advise would be to leave the parameters alone. Run the skimmer after cr to remove the excess carbonic acid. May I ask why are you running a cr for fowlr?It is normal for fowlr to have high ca and mg since there's literally nothing to consume them. Alkalinity would be affected by the organic acids. For your case, the alkalinity is also affected greatly by the cr.

[ming69]

I'm not running a fowlr. Just looking for salt that is meant for this sort of tank b'cos they have less mg and ca. My mg and ca are well over 1500 and 500 at the moment, which is the cause of the low KH. So unless I lower these two first, adding more sodium bicarbonate will not make much difference.

[MadScientist]

You can try tropic marin normal salt, it's rather low in everything. It seems to me that you do not need a cr as your tank's uptake of ca is not high enough and the cr is causing the low alkalinity.

Most people get by with just wc without additives in lightly stocked tank.

I would do a 50% water change for 2 days to reset the parameters and also disconnect the cr if I am facing your situation.

Trying out new phone taking pic of the zoas under blue led.

Finally the tank is looking more decent after moving to my new place.

Nice!

Nice!

Thanks, Bro!

Can you change the title of my tank? Now it's only 20" in height.

Yes! Now I can reach the sandbed without my plastic salad tongs

Amended title into inches for you.

lesser pain to siphon the sand lol
