Each one to their own.Well, pHplus is a 2.5 Molar (10%) Sodium Hydroxide solution. You definitely don't want that near anyone or anything that corrodes easily you care for.
I hope those bottles all come with safety instructions attached not just an orange danger triangle on the back. Because, with a product like that you should be prepared for dealing with spillage and appropriate first aid measures.
All the faff of DIY might actually help people understand what they are dealing with and take proper precautions. Instead of buying an off the shelf product in a fancy and safe looking bottle.
I mix myself, I don't go higher than 1M (2%).
I use a lab coat, eye protection and gloves. When switching out pHplus bottle, those wouldn't be such a bad idea either.
I don't use Reef Zlements , but I have been dosing in this pH-dependent manner for several years now.
I do have the KH dosing programmed to my pH on a Profilux. It works fantastically well. When I started working from home a lot during Covid my tank got into trouble with very low pH. This way of dosing ended up saving it.
I've tried all the pH raising techniques.
The pH-dependent dosing seems complicated but I find it much easier to tune and deal with than anything using kalkwasser.
My tanks always used to use 1.2 to 1.5 KH per day. The pH-dependent dosing took it to 2.6 KH per day.
A downside I noticed now I'm allying it to a new tank, is that you need a certain level of KH consumption to give you the room to tune your pH. I went from a 230L system to 900L. It uses now about 1 KH per day, for this tank that is too little to be able to really choose a pH.
In the basis I just use the Original Balling recipe. That is entirely based on using a 1 meq/L KH solution, so easy to calculate with.
I make Sodium Hydroxide, Sodium bicarbonate and Calcium chloride solutions myself. The Balling part C (Mag/NaCl free salt) I buy off the shelf. For traces I add the Fauna Marin Trace 1-3 bottles to the KH and Calcium mixes. Cheap and works perfectly.
So, yes, I'm also a fan of that way of dosing!
But it is interesting how do you know what pHplus has in it and you don't even use it - my guess is that you might be wrong but, then again I'm not going to argue with you because there is no point in doing so, and will lead nowhere productive
That's a good point, you do need a critical coral mass in order for dkh consumption be sufficiently large and allowing one to add sufficient amount of PH raising solution. If DKH consumption is near or below 1DKH per day - it would be a complete waste of time (and money).
Nowadays my tank is at 3 DKH a day - and I manage to floor PH at 8.1 at night, this raises 8.5-8.6 towards the end of the day. I mainly dose high PH solution during night hours, during the day it's sodium carbonate, still PH raising but less potent.
I have seen your tank on UR and I must say if you have 3dKH of consumption something is wrong, perhaps you have some precipitation going on because, doesn't look like your corals consumption would be 3dKH. But, again is my opinion without having measured it and only by seeing pictures of it.
Anyway, I think the 3 of us are in agreement that managing ph in this manner is actually a very successful way to do it and if you want to DIY your solutions fill your boots as, I'm defo not doing it
