What is PolypLab One?
PolypLab One is engineered from two forms of acetate and hydroxide salts. When dosed, the calcium magnesium ions are freely available for uptake by corals, clams, and many other reef organisms. The acetate ions are metabolized by bacteria to create biologically available biocarbonate. The hydroxide salts provide further buffering capabilities.
- Does not elevate salinity.
- Does not contain calcium carbonate.
- Phosphate and silicate free.

Q
Should I use this product if my alkalinity level is where I want it to be but my calcium level is not?
Will it raise my alkalinity level too high if I dose my tank and only my calcium level is low? Or if my magnesium level is low?
No, this product will effect alkalinity and magnesium in your tank in addition to calcium. It is designed to maintain the big three; calcium, alkalinity and magnesium in one solution. If you already are maintaining alkalinity with a different supplement, consider using a calcium only product such as the Brightwell Calcion.
CONS
there is something else in there (what else can I say)...

Well, I really liked the idea of doing a three part. Unfortunately, it didnt work out. There was something in my system and in the product which created a weird reaction. Big clots of gelatinous masses (looked like snot) developed in my sump. It was disgusting. Fortunately, no animals were harmed. I dont know what created the problem but I am back on good old Kalk. I didnt really need the Mg anyway.Hide
I've been using polylab lab for 10 days already my coral are happy and fluffy. Easiest way to dose your tank! Yeah it does does cloud your water temp but I does at night so it really doesn't bother me .
PROS
very convenient, only need to dose 1 time and no waiting 20+ minutes between mag, calcium, & alk supplements like other brands.
CONS
can cause too large of swings in a smaller tank
REVIEW
This seemed very convenient for my mixed reef. I dosed 1/2 of the suggested amount and started to experience browning on my rainbow montipora. I was using a brand that rhymes with med lee. I wanted this to work for my reef badly and maybe someone else will have better success with a larger tank...Read More
This seemed very convenient for my mixed reef. I dosed 1/2 of the suggested amount and started to experience browning on my rainbow montipora. I was using a brand that rhymes with med lee. I wanted this to work for my reef badly and maybe someone else will have better success with a larger tank than can absorb fluctuations better than my 8 gallon tank.Hide
Been Using this for two weeks now and I feel like I am getting great growth with my softies and everything seems to expand when I first add this to the tank. Does make the tank cloudy, but I do this first thing in the morning before I leave for work. Make sure you shake well before each use.
