arcticwolf Posted April 22, 2020 Report Share Posted April 22, 2020 My substrate has stopped buffering in my blue bolt tank .... not checked ph in about 2 weeks ... always been great .... it is now reading about 7 instead of the normal 6 to 6.5. This is my 10gal blue bolt planted tank .... had good breeding. Likely will need also to be changing the 30gal cbs before much longer as well. Need to know the safe way to do it. Have heard that a big substrate change can cause quick ammonia and nitrite spikes from loss of the beneficial bacteria. Also thinking i do not want the new substrate to do a real fast ph change and loose any of my shrimp or the week olds. In case someone knows about the substrate types i replacing the old shrimp stratum with Brightwell Aquatics FlorinVolcanit Rio Escuro-F. Seen reviews of this one working better and lasting longer, plus does real well with plants.kh 0gh 4tds 130 Thinking i need to change only a small part at a time perhaps over a few days .... but how much should i siphon out and replace at a time. 1/4 or less. Once a day, every other day. Once a week? No clue how fast substrate buffers. I know long term shrimp keepers have to change out substrate to keep active buffering. I can find no info about how to change it out. Only people saying it will need replaced when it quits buffering. Quote Link to comment Share on other sites More sharing options...
