weekly 10% change, no need dosing ca,mg,k... ?

[Milad]

hi guys
i plan to start a new tank with this method , please advice if this method is good or not
50G tank with bubble magus c7 skimmer
1-place 1 liter of matrix seachem in media bag and place in sump
2-using AF BIO S at first then after Ammonium and nitrite become zero dose daily AF PRO BIO S + NP PRO
3-run a UAS (Upper flow algae scrubber) and refugium with chaeto for better control on algae and phosphate,nitrate (if needed i,ll add Phosphate remover too)
4-weekly 10% change with good salt and tds 0 water and dosing KH based on tests to keep at at 8-9dlk range.
------------------
if this method is good , here is my main ques:
i gonna keep 6,7 small,medium size fish and 2 anemone, 1 sps, 1 lps and some zoa polyp , that 10% weekly change will provide enough Ca,Mg,K, Strontiumو Fe, iodine and keep them at normal range for that amount of reef?

Water changes will likely keep up for some time. When your hard corals and coralline algae take off, you will likely need to supplement.

HW wiegandt reefer salt mix will help you if you want an alk around 8 or so as well as replenishing trace elements, also until full of coral I didnt dose until about 10 months of having a lot of frags. I doubt you need a scrubber, refugium, and a protein skimmer. Thats a bit much imo. you better be stocking heavy. lol

i dont plan to have heavy corals in my tank since i love fish more than reefs
so that method along 10% weekly change will be enough for other elements except KH?

I think you would be fine without dosing alkalinity.... just test the consumption over the week once you have coral to figure out how stable you are remaining bw waterchanges. testing is key.

so maybe i wont need dose kh considering that method and 10% weekly change right? but i,ll do test kh and Ca for sure.
water change wont increase one element more described in salt info ? for example if Ca is 1400ppm in salt info, changing 40% monthly wont make it higher than 1400ppm ?

 

[Milad]

this is the tank in my mind , a few reef and alot liverock with some fish,
that method i mention above is enough to control no3 and po4?
and 10% water change will provide all elements for this ? (except kh)

 

[salty_trout]

i highly doubt there would be a need to dose for alkalinity (kh) with a tank like that, with appropriate water changes and good salt it should cover all bases. I prefer a 20% when i do a water change.

You will probably be fine not dosing, but in my opinion I would still test alk & calc regularly. It's not hard and then you wont be guessing as to whether the water changes are keeping up or not, you will know and be able to make adjustments accordingly.

 

[DarthSimon]

Just watch your parameters. If they stay stable, water changes will suffice. If they swing on a regular basis, your tank will tell you it's time to start dosing.

 

[LIreefguy]

I would strongly advise just dosing alk and not Calcium

Dosing alk only can cause your calcium to drop too slow

It is much better to dose a 2 part evenly then only one element alone

The reason why alk always drops faster than calcium is because your tank has a lot more calcium in it then carbonate

Also remember when your dosing 2 part the 2 solutions are balanced according to how most corals use it naturally in your tank (not 100 percent but close )

thanks alot guys for advice
so with weekly 10% change for that kind of tank (in that image) at max i may need dos alk and Ca (after testing)

about that method for control no3 and po4 , it would be enough?
1-place 1 liter of matrix seachem in media bag and place in sump
2-dose daily AF PRO BIO S + NP PRO
3-run a UAS (Upper flow algae scrubber) and refugium with chaeto

I run a 135g mixed reef with a 100g Rubbermaid sump with probably 20 frags, do 15% weekly water changes via Apex DOS and I've never had to dose anything - tank has been running for close to two years.

All you really need to do is consistent water changes. You don't need all that equipment. Here's 90 gallon system that gets roughly 15% water changes every 2-3 weeks with tapwater, Equipment is a single Mag 9.5 and a tetra air pump. Sump is about 40 gallons. Dosing is very sporadic and only consist of adding bicarbanate to the makeup water. here's ATI Aquaristik ICP test results of the system. Here's ATI Aquaristik ICP test results of the tapwater.

changing 10% weekly at once is ok? (siphon 10% and then add 10% new salt water by a little pump)
adding tapwater at once is ok too? (about 3 liter for 250 liter tank) , my RO/DI is far from tank so cant use floater

Yes thats what I do

RO/DI is fine for top off. I would add the top off water each day to keep your salinity more stable.
I do not know what is in your tap water

Yes, changing 10% weekly at once is ok. With my systems I mix the water in 5 gallon buckets and just dump in the water all at once when the water clears up, about 15 minutes. I aim for ~20% to ~30% monthly. With the system linked in my first post new saltwater is made up with tapwater, no RO is used, and salinity is adjusted low to account for evaporation. The system doesn't have an ATO so the ~20 gallon water change may be only half strength so the system may be seeing a 10% change in salinity with the water change. You can click on the link to see the ICP test results for the tap water used, TDS is roughly 300-350.
