**Aquarium Safe Epoxy Resin - MAX ACR A/B 96 Ounce Kit for Coating, Casting, Sealing & Fiberglassing - Freshwater & Saltwater Safe - Ideal for DIY Plywood Aquariums, Koi Ponds & Concrete Sealant - Perfect for Home Aquariums, Fish Tanks & Water Feature Projects**

I have ordered over $1000 of this epoxy along with their aquarium safe epoxy adhesive for my 750 gallon plywood aquarium build and had almost zero problems. I went overboard with multiple coats of resin and fiberglass. The only issue is alligatoring pattern when applying over fiberglass. This can be corrected with some sanding and heavy coats of the epoxy or "omitting the fiberglass" which is suggested. I really needed the extra strength of the fiberglass so I was willing to use more epoxy than needed. It mixes well with colorants and mica powders. Use of gram scales down to the hundredths of a gram is recommended when mixing 2 to 1 ratio. If you want really knowledgeable info on their products call their website. They make superb products! Pictures to come when nearing completion!
