  1. Hello. Been some time since I followed up. I just want to say- the super peat & driftwood in my tank has worked amazingly well. PH stays low and stable. And i just use sand as a substrate. CRS are breeding like crazy.
  2. Hmm. I think you are right. 1. I only added a small amount of pellets, hence the small drop. I may add more, but I wanted to go slow and steady. I’ve used a fair amount peat pellets without co2 in my tap water (7.2 ph) and gotten to around 6.0. As far as I can tell, my tap has basically 0 kh. 2. So active substrates stop the ph from dropping too low? The keep it at a specific number? That is really helpful to know if true. 3. Regarding adding kh- you are definitely right that adding kh will cause the peat to exhaust faster, because the two are working agains
  3. Good point!! I’ll do some experiments out of the tank to figure out the ph with only SS gh added. I will likely try to shoot for a KH of 1 to provide some buffering capacity. May even mix a little gh/Kh into the SS gh to get there if I need. I was running co2 for a while, and had the peat. KH was 0, and the ph swings were wild. I imagine that was a due to the lack of a buffer with co2 turning on and off. Not going back there!
  4. Not a bad idea to put buffering substrate in the filter as media; probably in a mesh bag for easy changes. I already have the peat. So I’ll use it til it’s gone. It does provide other benfits- releases humic and fulvic acids (like alder cones and almond leaves) and lowers KH and gH if you have a enough pellets. It aldo removed heavy metals from the water (or sonthe box says). My LFS guy swears by it. I did put a small bag back in my filter yesterday. Lowered ph from 6.8 to 6.6 and kh from 3ish to 1ish. All is stable now.
  5. Thanks for the reply— I think the strength/duration of the peat pellets is based upon the water one uses it in and how much you add. Since my water is soft to begin with, I’m fairly certain the pellets will last a lot longer. In hard water, they become exhausted more quickly. I used them in the past in a planted tank, and it kept a very low ph (bottom of my liquid test kit chart) for many months. The pellets also release humics and fulvics, which I understand to be beneficial to shrimp— part of the reason ppl use Alder cones and capata leaves, etc. so, I guess my ques
  6. Hi all, Question regarding Sera Super Peat Pellets. It is a suitable alternative to a buffering substrate? In the past, I have placed the pellets in my canister filter. It reliably lowers PH (as well as kh) over long periods. Does the substrate offer other benefits? I ask because I am interested in moving from neos to Cardinia species, but I’d rather not tear down my tank. So the pellets seem like a good option. Current tank parameters without peat pellets, using Salty Shrimp gh/kh. PH: 6.7 GH 7 KH: 2 TDS: 210
