Hydrospace, an innovator in microbial products for aquarium and aquaculture applications, is
excited to announce additional expansions of its product offerings with the introduction of one-gallon sized PNS ProBio™ and PNS Deep Cycle™, as well as an upgraded, more user-friendly PNS HomeGro™ kit.
These developments come in response to increasing consumer demand for upsized alternatives to Hydrospace’s trusted microbial solutions. Both the new/improved PNS ProBio and PNS HomeGro contain the ‘Big 3’ purple nonsulfur bacteria (PNSB) of the aquaculture world: Rhodopseudomonas palustris, Rhodospirillum rubrum, and Rhodobacter sphaeroides. Deep Cycle was likewise upsized to meet increasing demand for that product's beneficial, reef-indiginous microbes.

For those simply looking for larger versions of the PNS ProBio™ and PNS Deep Cycle™ they are already familiar with, the new one-gallon size (treats around 3,200 gallons) will be a welcome addition. Previously only offered in a 16-ounce bottle, the larger options provide a more cost-effective and environmentally friendly solution for aquaculturists and hobbyists alike. Packaged in a rigid HDPE slant handle jug paired with a sturdy 38/400 ribbed polypropylene cap and F217 liner, it is exceedingly simple to pour, re-seal, and store.

For those with the time, space, and desire to cultivate even larger quantities, PNS HomeGro™
offers an excellent opportunity to grow the ‘Big 3’ PNSB efficiently and sustainably at home. Previously available exclusively through Hydrospace, this kit is now easier than ever for hobbyists to access from an array of reputable online and brick-and-mortar stores. In addition to sturdier and more attractive packaging, this upgraded version of the kit features several add-ons such as an adhesive digital thermometer and a detailed instruction sheet.

The new one-gallon PNS ProBio™, one-gallon PNS Deep Cycle™, and the upgraded PNS HomeGro™ kit are all available from Hydrospace through its growing network of retailers. Wholesale inquiries are best directed to Aquarium Supply Distribution (ASD) at https://aquariumsupplydistribution.com.
