Does this seem like a large amount of CaSO4 and MgSO4

I just received my CaSO4 and MgSO4 from GLA and I just ran the numbers using the nutrient calculator. It says to dose 17.274g of MgSO4 and 17.359g of CaSO4. It just seems a little, excessive. Is anyone else with a large tank dosing that much once a week?

How big is the tank? Are you trying to dry dose daily of make a 500ml liquid solution in a bottle?

It's my 90g and it would be a single dry dose weekly.

If it's the same one in your signature line I didn't see CO2 listed in the OP (which is as far as I've looked ATM) and I've seen it posted (and so suggested to me personaly) that non CO2 injected tanks should start with 1/2 of the recomended EI dosing, as these caculations are typically based on high light and CO2 injection.

I thought a good ratio was 3 CA/1 Mg?

It's CO2 injected. I run full EI dry dosing daily with:
4.166g KNO3 Mon/Wed
.634mg KH2PO4 Mon/Wed/Fri
1.693g K2SO4 Mon/Wed and 3.591g Fri
2.609g CSM+B Tue/Thu/Sat
Sunday 50% WC
I would dose the MgSO4 and CaSO4 on Sunday after the WC

Actually the quantities (in grams) listed will provide a 3:1 Ca:Mg ratio.

Similar results would be accomplished with 3.5 teaspoons of MgSO4 and 6.0 teaspoons of CaSO4.

That said, it does seem a little excessive to me. If I were dosing at that level I would monitor my dKH and dGH and verify that the hardness does not substantially increase over a month or two and be sure to maintain the weekly water changes.

The calculator states its 3:1 because the MgSO4 dose would be 5ppm for Mg and the CaSO4 dose would be 15ppm for CA.

That's exactly what I was thinking

In my 55 gallon, I dose 2TB of CaSO4 and 2 tsp of MgSO4. That's more than your 17gms of either. It achieves 20+ppm of Ca and 4+ppm of Mg.

Hi Brandon,

Both Puyallup and Summit source most of their water from springs and wells so knowing the dKH and dGH of your tap water may help you determine an appropriate dosing level.

Thanks for the good info Roy. I just found my local water report and I'm at 72ppm out of the tap so fairly soft water.
Snails cannot survive long in any of my tanks either. I have the standard pest snails, trumpet snails, and ramshorn snails. All of them grow pretty small and die off fast. Their shells all look chipped and crumbling before they die. That all pointed me in the direction of increasing hardness.
