I just bought some coconut coir fiber to use with some terrariums I'm making and I'm wondering if I can use some in my aquarium filter instead of peat, to lower my PH a bit and soften the water?
It takes a lot of tannins to lower the pH to neutral side assuming the KH is high. Then again, pH is not something to look out for but the KH.One of the advertised 'benefits' of coconut choir is the closer to neutral ph in comparison to the acidity of peat, I doubt it would hurt anything assuming it was processed for live animals, however it may not do what you are hoping for.
Beyond my scope - no experience here as to KH, I have dealt with foreign objects in coco fiber before though and after numerous emails back and forth with the folks who produce bed-a-beast and eco-earth I've come to know that the addition of unwanted extras (plastic, metal pieces, unidentifiable garbage) is a battle the processors are always fighting, I've found a lot more garbage in coco fiber as compared to peat over the years, tho it sems to be getting better - or I've just gotten a bit luckier. Always a good plan to do a once over before use regardless.It takes a lot of tannins to lower the pH to neutral side assuming the KH is high. Then again, pH is not something to look out for but the KH.
I don't think that is an issue. You're fine without having to add peat, coco fiber, etc.OK maybe you can help me understand this a bit better lupin. my PH is 7 but I want it around 6.5 or 6.8 since I have south Asian fish. I thought they like soft water but maybe Im not really understanding what the difference between soft water and low Ph is. lol I'll admit to being a aquarium chemical noob.erv:
